Quick answers about sending faxes, receiving faxes, editing PDFs, credits, and more
Sending a Fax
Do I need an account to send a fax?
No. FaxSeal requires zero signup. Upload your PDF, enter the recipient fax number, pay, and your fax is sent. Nothing else.
Sending a Fax
What file types can I fax?
PDF files only, up to 20MB. If your document is a Word file or image, convert it to PDF first — most browsers have a built-in "Print to PDF" option.
Sending a Fax
How many pages can I send?
Quick Send ($1.29) — up to 5 pages. Standard ($1.99) — up to 15 pages. Pro ($3.49) — up to 30 pages. The right plan is selected automatically based on your document's page count.
Sending a Fax
What countries can I fax to?
US, Canada, and international fax numbers are all supported. US/CA numbers can be entered as (555) 123-4567. International numbers must use E.164 format with the country code (e.g. +44 20 7946 0958 for UK). International destinations are billed at 2–3× the standard rate depending on the destination country.
Sending a Fax
Will I get a delivery confirmation?
Yes. Enter your email at checkout and we'll send a receipt once your fax is confirmed delivered. No account is created.
Receiving a Fax
How do I receive a single fax?
The 24-Hour Fax Number plan ($2.99) gives you a temporary US fax number valid for 24 hours. Share the number with whoever needs to fax you. When the fax arrives, we email you a PDF download link instantly. Your card is only charged if a fax actually arrives.
Receiving a Fax
What is a dedicated fax number?
A dedicated fax number is a permanent US number that belongs to your account as long as you subscribe. Every fax sent to it lands in your inbox as a PDF, with text automatically extracted so you can search it. Four plans are available: Receive-Only ($2.99/month, inbound only), Personal ($4.99/month, send + receive), Business ($14.99/month, high-volume), and Enterprise ($49.99/month).
Receiving a Fax
What is the difference between fax number plans?
All plans give you a permanent dedicated fax number with a searchable inbox and OCR. Receive-Only ($2.99/month) is inbound-only — no sending. Personal ($4.99/month) adds outbound sending and caller ID. Business ($14.99/month) is built for high-volume offices — 1,000 pages/month included, $0.01/page overage. Enterprise ($49.99/month) covers 5,000 pages/month.
Receiving a Fax
Can I search inside received faxes?
Yes. FaxSeal automatically reads the text from every fax you receive using AI text recognition. You can then search your entire inbox by keyword — patient name, case number, invoice ID, or any word that appears inside the document. Results show the matching passage highlighted in context.
Receiving a Fax
How long does text extraction take?
Typically 15–30 seconds after the fax arrives. The extracted text appears automatically in your inbox — no action needed. While extraction is running you will see "processing…" on the fax card.
Receiving a Fax
Can I forward a received fax by email?
Yes, two ways. Manual: each fax in your inbox has a Forward button — enter any email address and we send the PDF plus the full extracted text. Automatic: use the Auto-Forward setting on the fax number page to have every inbound fax emailed to up to 5 addresses instantly (limit depends on your plan), without logging in.
Receiving a Fax
Can I download the extracted text as a file?
Yes. Faxes with completed text extraction show a TXT button alongside the View PDF button. Clicking it downloads a plain-text file of the extracted content, including the sender number, page count, and date at the top.
Receiving a Fax
Can I delete received faxes?
Yes. Each fax card has a delete button (×). You will be asked to confirm before it is removed. You can also clear your entire inbox at once using the "Clear all" option at the top of the inbox. Deleted faxes and their stored PDFs are permanently removed.
Receiving a Fax
What happens if I receive a lot of faxes on the Personal plan?
The Personal plan includes up to 200 inbound pages per calendar month. Faxes that arrive after the limit is reached are stored in your inbox as blocked stubs — you can see who sent them and how many pages — but the PDF is not delivered until you upgrade. You will also receive an email notification for each blocked fax. The Business plan includes 1,000 pages/month — additional pages are billed at $0.01/page. Enterprise includes 5,000 pages/month with the same $0.01/page overage.
Receiving a Fax
Can incoming faxes be automatically emailed to me?
Yes — this is called Auto-Forward. On any dedicated number plan you can add email addresses under Settings on the fax number page. Every inbound fax is automatically emailed to those addresses as a PDF attachment the moment it arrives — no inbox login needed. Receive-Only plans support 1 address, Personal supports 2, and Business/Enterprise support up to 3. This is ideal for offices that want faxes to land directly in an email inbox without anyone needing to log in.
Edit & Sign PDFs
Is editing and signing a PDF free?
Your first sign each day is free — no account or credit card needed. A sign is counted when you tap "Done" in the editor and the signature is applied, not when you download. If you need to sign more PDFs the same day, additional signs are $0.99 each. Re-editing a document you already signed today is free. Downloads never have watermarks.
Edit & Sign PDFs
What can I do in the PDF editor?
The editor supports: draw or type a signature, add text annotations, add dates, remove pages, rotate pages, and merge multiple PDFs. All tools are free with no account required. You can also fax the edited document directly from the editor.
Edit & Sign PDFs
Can I sign on mobile?
Yes. The signature pad and editor are touch-optimized. Draw your signature with your finger, drag annotations into position, and tap the edit or delete buttons.
Edit & Sign PDFs
Can I type my signature instead of drawing it?
Yes. On the signature pad, switch to the "Type" tab to type your name and pick a handwriting-style font.
Edit & Sign PDFs
Can I edit text or date annotations after placing them?
Yes. Tap the blue pencil button (✎) on any text or date annotation to edit it inline. On desktop, double-clicking also works.
Edit & Sign PDFs
Can I merge multiple PDFs?
Yes. In the editor you can add multiple PDF files and reorder, rotate, or remove individual pages before downloading or faxing the combined document.
Send as Email
What is "Send as Email"?
Send as Email lets you upload a PDF and deliver it as a professional email attachment directly to any recipient's inbox — no fax machine needed. It uses the same credit as a standard fax (1 credit per send) and includes your optional note in the email body.
Send as Email
How is Send as Email different from a regular fax?
A fax is transmitted over the phone network to a fax machine or fax number. Send as Email delivers your PDF as an attachment directly to an email address — faster, no fax machine required on either end. Both cost 1 credit.
Send as Email
What is the file size limit for Send as Email?
PDFs up to 10MB can be sent as email. This is lower than the 20MB fax limit because most email providers (Gmail, Outlook) reject attachments over 10MB on the receiving side.
Send as Email
Does the recipient need a FaxSeal account?
No. The recipient gets a standard email with your PDF attached. They do not need FaxSeal or any special software.
Send as Email
Will I get a confirmation when my document is delivered?
Yes. You receive an email confirmation once the document is sent. If delivery fails for any reason, your credit is automatically restored.
Send as Email
Do I need credits to use Send as Email?
Yes — Send as Email costs 1 credit per send and requires a signed-in account. Credits never expire and can be purchased from the Credits page.
Fax by Email
What is Fax by Email?
Fax by Email lets you send a fax from any email app — Gmail, Apple Mail, Outlook, anything. Compose an email, attach a PDF, and address it to the recipient's fax number followed by @faxseal.com (e.g. [email protected]). FaxSeal faxes the PDF automatically.
Fax by Email
Who can use Fax by Email?
You must have a FaxSeal account and the email you send from must match your account email exactly. If you sign in with [email protected], you must send from that same address. FaxSeal looks up your account by sender email to verify credits.
Fax by Email
What format should the To address be?
Use the full fax number (with country code) followed by @faxseal.com. Examples: [email protected] or [email protected]. The number must be a valid fax number reachable via the phone network.
Fax by Email
Does my email subject and message get included?
Yes. If you include a subject or message body, FaxSeal automatically prepends a cover page to your fax with the date, recipient number, your email address, subject, and message — just like a traditional fax cover sheet.
Fax by Email
What happens if something goes wrong?
FaxSeal replies to your email in every error case: unrecognised sender (no account), no PDF attached, PDF too large, insufficient credits, or storage failure. Your credits are never charged unless the fax is successfully queued.
Fax by Email
I sent an email but got "no account found" — why?
The email address you sent from is not registered as a FaxSeal account. Sign up at faxseal.com using that same email address, add credits, and try again. FaxSeal identifies you by your sender email — it must match your account exactly.
Fax by Email
I got "no PDF attachment found" — why?
FaxSeal only processes PDF files attached to the email. Forwarded emails, inline images, Word documents, and emails with no attachment are not supported. Attach a PDF file directly and resend.
Delivery Receipts
What is a certified delivery receipt?
Every fax delivered through FaxSeal generates a certified delivery receipt — a tamper-evident PDF that records the job ID, delivery timestamp, sender and recipient numbers, page count, and a SHA-256 hash of the exact document transmitted. It is included as a download link in your delivery confirmation email. Free on every fax.
Delivery Receipts
What is a SHA-256 hash and why does it matter?
A SHA-256 hash is a 64-character fingerprint of the document. If even one character in the document changes, the hash changes completely. By comparing the hash on the receipt to the hash of your file, you can prove the exact bytes you sent were the ones that were transmitted — no alterations possible.
Delivery Receipts
How do I verify my receipt?
Open the verification page linked in your delivery email (faxseal.com/verify/[jobId]). Then hash your copy of the PDF using: macOS/Linux: shasum -a 256 yourfile.pdf — Windows: certutil -hashfile yourfile.pdf SHA256. Compare the output to the hash shown on the page. A match proves the document was not altered.
Delivery Receipts
Can I use this as legal proof of transmission?
The certified receipt provides strong evidence of fax transmission — a delivery timestamp, sender/receiver numbers, and a cryptographic hash of the transmitted document. Courts and healthcare regulators routinely accept fax transmission records as evidence. For the highest level of legal certainty, consult your attorney about whether a third-party timestamping authority (RFC 3161) is required for your jurisdiction.
Delivery Receipts
Where can I find my receipt after delivery?
The receipt download link is included in the delivery confirmation email FaxSeal sends when your fax is delivered. You can also go directly to faxseal.com/verify/[jobId] where [jobId] is the job ID shown in your email.
Delivery Receipts
Is there a charge for the certified receipt?
No. Certified delivery receipts are generated automatically on every successfully delivered fax at no extra charge.
Credits & Pricing
Where can I see all pricing in one place?
Visit faxseal.com/pricing for a full breakdown — send tiers, credit packs, 24-hour temp numbers, and dedicated number plans (Receive-Only, Personal, Business, Enterprise) all in one page.
Credits & Pricing
What are fax credits?
Credits are a pre-paid alternative to per-fax card payments. Credit cost depends on page count: 1–5 pages = 1 credit, 6–15 pages = 2 credits, 16–30 pages = 3 credits (US/Canada). International destinations multiply that: ×2 for Europe, AU, JP and major markets; ×3 for the rest of world. One credit also delivers a PDF as an email attachment (Send as Email). Credits never expire.
Credits & Pricing
How do I buy credits?
Sign in, then visit the Credits page. Packs start at $12.99 for 10 credits ($1.30 each). The Pro Pack pack ($24.99 for 30 credits) is most popular.
Credits & Pricing
Do credits expire?
No. Credits never expire and carry over indefinitely.
Credits & Pricing
Can I schedule a fax to send at a specific time?
Yes — credit users can schedule a fax up to 30 days in the future. On the send page, use the "Schedule for later" picker above the Send button to choose your date and time. The fax is queued immediately and sent automatically at the scheduled time. Scheduling is available on the credits path only; pay-per-fax sends are immediate.
Credits & Pricing
What is Broadcast Fax?
Broadcast Fax lets you send one PDF to multiple recipients at the same time — up to 500 recipients per broadcast. Go to Dashboard → Broadcast, upload your PDF, then paste fax numbers (one per line) or import a CSV. Credits are deducted upfront based on page count and destination per recipient — see "How are credits calculated for a broadcast?" below. All recipients share the same document; each gets their own certified delivery receipt and track link.
Credits & Pricing
How are credits calculated for a broadcast?
Broadcast cost = per-recipient credit cost × number of recipients. Per-recipient cost (US/Canada): 1–5 pages = 1 credit; 6–15 pages = 2 credits; 16–30 pages = 3 credits per recipient. International recipients cost 2–3× more. Example: a 3-page fax to 50 US recipients = 50 credits total. The exact total is shown before you confirm and deducted atomically on submit — if your balance is insufficient, the broadcast is rejected and no credits are taken.
Credits & Pricing
Can I import a list of fax numbers for a broadcast?
Yes. On the Broadcast page, click "Import CSV" and upload any plain-text file with one fax number per line (commas and semicolons also work as delimiters). Numbers are added to the recipient textarea where you can review and edit them before sending. US, international, and E.164 formats are all accepted.
Credits & Pricing
Can I use credits to sign and fax a PDF?
Credits apply to the standard fax flow (/send). The sign-then-fax flow currently uses per-fax card pricing. Signing itself is always free.
Credits & Pricing
Is payment secure?
Yes. All payments are processed by Stripe. FaxSeal never stores your card details.
Account & Privacy
Do I have to create an account?
No. Faxing, editing, and signing work without any account. Signing in (via Google or email) lets you save documents, use credits, manage contacts, get a dedicated fax number, and create or join a team workspace.
Account & Privacy
Is my document stored permanently?
No. Files are stored only long enough to transmit your fax, then deleted automatically. Signed-in users can optionally save documents to their account; those are kept until you delete them.
Account & Privacy
Does FaxSeal sell my data?
Never. Your documents and fax numbers are used only to deliver your fax. See our Privacy Policy for full details.
Teams
What is a team workspace?
A team workspace lets multiple people share a fax inbox, contacts, documents, and a credit pool under one account. Create a team from your dashboard, invite colleagues by email, and everyone works from the same shared space.
Teams
How do I create a team?
Sign in, go to your dashboard, and click "Create Team" (or visit /dashboard/org/new). Give your team a name — you become the owner automatically. Then invite teammates by email from the team management page.
Teams
How do I invite a teammate?
From the team page, enter their email address and choose a role (Member or Admin). They receive an email with an invite link valid for 48 hours. If they don't have a FaxSeal account, they'll create one when accepting.
Teams
What is the difference between Owner, Admin, and Member?
Owner can do everything including delete the team and manage all members. Admin can invite and remove Members but cannot manage other Admins or the Owner, and can manage the team's anonymous inbox handle and fax number. Member can use all shared resources (inbox, contacts, documents, credits) but cannot manage team membership, the fax number, or the inbox handle.
Teams
How do shared credits work?
Credits purchased while in team context are added to the team pool, not your personal wallet. Any team member can spend from the pool when they send a fax in team context. The credit log shows who spent what.
Teams
Can I switch between personal and team context?
Yes. Use the workspace switcher in the top-left of your dashboard to toggle between "Personal" and any teams you belong to. Your personal documents and credits are always separate from team resources.
Teams
Can I belong to multiple teams?
Yes. You can be a member of multiple teams and switch between them freely. Each team has its own inbox, contacts, documents, and credit pool.
Teams
How do I leave a team?
Go to the team page and click "Leave" next to your name. If you are the sole owner, you must transfer ownership to another member first before leaving.
Partner API
What is the FaxSeal Partner API?
The Partner API lets software companies embed fax capability directly into their products. You provision dedicated US fax numbers per user via API, receive webhooks when faxes arrive (with OCR text and AI-extracted structured data), and send outbound faxes from your users' numbers. Your end-users never see FaxSeal — it is invisible infrastructure inside your platform.
Partner API
How do I get a partner API key?
Go to faxseal.com/partners/apply. Enter your company name and billing email, verify your address, and your API key (sk_partner_...) is issued instantly. Read the full API reference at faxseal.com/docs/partner before integrating.
Partner API
What is the partner portal and how do I access it?
The partner portal is a dedicated dashboard at faxseal.com/partner that gives your team visibility into your partner account — active numbers, credit balance, usage stats, billing status, API key, and webhook settings. Access is granted by your FaxSeal account manager. Once assigned, a "Partner Portal" button appears in your standard FaxSeal dashboard. You must have an existing FaxSeal account to be added as a member.
Partner API
What are the partner portal team roles?
There are four roles: Owner (full access including team membership management), Admin (operational access, no membership changes), Billing (billing status and credit balance only), Developer (API key, webhook settings, usage stats — no billing or team management). Only one owner can exist at a time; transferring ownership atomically demotes the previous owner to admin.
Partner API
How does partner billing work?
You are invoiced monthly via Stripe for each active provisioned fax number. Invoices go to the billing email on your account. Overdue invoices trigger a grace period (configurable by your account manager) before API access is suspended. Access reinstates automatically when payment is received. Outbound faxes deduct from your prepaid credit balance — credits never expire.
Partner API
Can partner users send outbound faxes?
Yes. POST /api/partner/fax with a PDF (upload or URL) and the externalUserId of the sending user. The user's provisioned fax number is used as caller ID automatically. Credits are deducted from your partner balance. Status webhooks (fax.sending, fax.delivered, fax.failed) fire to your configured endpoint. Returns 422 if the user has no provisioned number, 402 if credits are insufficient.
Partner API
Do my users need FaxSeal accounts?
No. FaxSeal uses shadow user records keyed to your own externalUserId. Your users never interact with FaxSeal directly — fax numbers, inboxes, and webhooks are all managed through your platform using your API key.
Enterprise & SSO
What is the Enterprise Organization Plan?
The Enterprise Organization Plan ($199/month per organization) adds SSO, automatic team provisioning, and priority support to your workspace. It is billed per organization — not per seat. Upgrade from your organization settings in the dashboard.
Enterprise & SSO
What is SSO and why does my organization need it?
SSO (Single Sign-On) lets your team sign in to FaxSeal using your existing company credentials — Okta, Microsoft Entra ID (Azure AD), Google Workspace, or any SAML 2.0 / OIDC identity provider. Instead of managing individual FaxSeal passwords, your IT team controls access centrally. Deactivating an employee in your IdP blocks new FaxSeal logins immediately; use "Remove & Revoke" in Organization Settings to also terminate any existing active sessions.
Enterprise & SSO
Which identity providers are supported?
FaxSeal SSO supports any SAML 2.0 or OIDC provider, including Okta, Microsoft Entra ID (Azure AD), Google Workspace, OneLogin, PingFederate, and JumpCloud. If your IdP supports SAML 2.0, it works with FaxSeal.
Enterprise & SSO
How do I set up SSO for my organization?
Upgrade to the Enterprise Organization Plan from your org settings in the dashboard. Then go to Organization → SSO Settings and enter your SAML connection ID from your identity provider. Once saved, anyone who signs in to FaxSeal with a matching company email domain is routed through your IdP automatically.
Enterprise & SSO
Do my teammates need to be invited individually?
No. With SSO enabled, any user whose company email matches your organization's domain is automatically added to your workspace as a Member on their first sign-in. No invite emails, no manual provisioning. You can still invite users with different email domains manually if needed.
Enterprise & SSO
Can I prevent team members from signing in with Google or a magic link?
Yes. When Enterprise SSO is active for your domain, FaxSeal automatically blocks magic-link (email) sign-in for addresses on that domain and redirects them to your IdP. Google sign-in is not blocked at the FaxSeal level — enforce that restriction in your Google Workspace admin console if needed.
Enterprise & SSO
How do I offboard an employee immediately?
Two steps for complete offboarding. (1) Deactivate them in your IdP (Okta, Azure AD, etc.) — this blocks any new FaxSeal login attempt via SSO, but their existing session stays valid for up to 30 days. (2) Go to Organization Settings → Members, find the user, and click "Remove & Revoke" — this removes them from your workspace and immediately invalidates all active sessions. Do both for instant, complete access removal.
Enterprise & SSO
What happens if our Enterprise plan lapses or is cancelled?
If the Enterprise plan is cancelled or payment fails, SSO logins for your domain are suspended — affected users will see a sign-in error until the plan is restored. Existing accounts and data are not deleted. You can reactivate the plan at any time from your organization settings.
Troubleshooting
What if my fax fails?
If the recipient line is busy, unreachable, or rejects the fax, the status shows "failed" and your payment authorization is automatically released — your card is never charged. You can retry or contact support.
Troubleshooting
How long does a fax take to deliver?
Most faxes deliver within 1–3 minutes once transmission begins. Busy lines or slow recipient machines can take longer. During high platform load, faxes are queued in order received and may wait briefly before transmission starts. The Track page shows live status.
Troubleshooting
My PDF failed to upload — what should I try?
Make sure your file is a valid PDF under 20MB. Encrypted or password-protected PDFs are not supported. Try opening the PDF in your browser and re-saving it.
Troubleshooting
I received a fax but the text extraction shows "processing…" — what should I do?
Text extraction usually completes within 30 seconds. If it still shows processing after a few minutes, try refreshing your inbox. If it remains stuck, contact support — we can manually trigger re-extraction.
Automation & AI
Can I send faxes from Zapier or Make?
Yes. Create an API token at faxseal.com/dashboard/api-tokens, then use it as the Bearer token in any Zapier or Make HTTP action. You can trigger faxes from Google Sheets, HubSpot, Airtable, or any app that supports webhooks — no code required.
Automation & AI
Can I send faxes from ChatGPT?
Yes. Open the FaxSeal GPT at chatgpt.com and sign in with your FaxSeal account. You can then send faxes, check delivery status, and check your credit balance just by chatting — no token copy-paste needed.
Automation & AI
Can I send faxes from Claude?
Yes, via the FaxSeal MCP server. If you use Claude Code, run: claude mcp add faxseal -e FAXSEAL_API_KEY=your_token -- npx faxseal-mcp. After that, you can send faxes by natural language directly inside Claude. Your token is available at faxseal.com/dashboard/api-tokens.
Automation & AI
Can I send faxes from my own code or scripts?
Yes. Use any HTTP client with Authorization: Bearer your_token on every request. The full API reference with code examples in curl, JavaScript, and Python is at faxseal.com/docs/api.
Anonymous Inbox
What is the Anonymous Inbox?
The Anonymous Inbox gives you a public link — like faxseal.com/inbox/yourname — that anyone can use to send you a PDF document. The sender never sees your fax number or email. The document is faxed directly to your dedicated FaxSeal number. It is ideal for journalists, lawyers, doctors, HR teams, or anyone who needs a secure public-facing submission link.
Anonymous Inbox
How do I set up my inbox handle?
Go to Dashboard → Inbox Link. Choose a handle (3–30 characters, letters, numbers, and hyphens). Once saved, your public link is live immediately. You must have a dedicated fax number on your account — the document is faxed to that number when someone submits.
Anonymous Inbox
Does the sender need a FaxSeal account?
No. Anyone with your link can submit a document — no account, no login, no payment. They just upload a PDF and optionally include their name, email, and a message. That is it.
Anonymous Inbox
Where does the document go when someone submits?
The document is faxed directly to your dedicated FaxSeal fax number. It arrives in your regular fax inbox just like any other received fax — with a cover page showing the sender's name and message if they provided one. You also receive an email notification with the sender's details the moment the submission arrives.
Anonymous Inbox
What does a submission cost?
Each inbox submission costs the same as sending a standard fax: 1 credit for 1–5 pages, 2 credits for 6–15 pages, 3 credits for 16–30 pages (US/Canada). Credits are deducted when the fax is queued for delivery, not when it is delivered.
Anonymous Inbox
Can I pause or delete my inbox handle?
Yes. From Dashboard → Inbox Link you can pause your handle at any time — submissions will be declined while paused, but your handle URL is preserved. You can also delete the handle entirely, which frees up the name immediately.
Anonymous Inbox
Is the submission truly anonymous?
Yes from the sender's perspective — your fax number and email are never disclosed. Senders can optionally include their name and email if they want a reply, but both fields are optional. If they leave everything blank, their submission arrives with no identifying information.
Anonymous Inbox
Why do I need a dedicated fax number to use the inbox?
The inbox routes submitted documents to your fax number so they arrive as real faxes — with a certified delivery receipt, just like any other inbound fax. Without a dedicated number there is nowhere to deliver the document.
Anonymous Inbox
Can a team workspace have its own inbox handle?
Yes. When you switch to a team workspace in your dashboard, the Inbox Link page manages a handle that belongs to the team — not any individual member. Submitted documents are faxed to the team fax number, credits are drawn from the team pool, and all team owners and admins receive email notifications on every submission. Only owners and admins can create, change, or pause the team inbox handle.
Anonymous Inbox
Can I receive inbox submission notifications via webhook?
Yes. Any API token with a webhook URL configured will receive an inbox.submission event payload the moment a document is submitted — before the fax is even sent. The payload includes the handle, sender name, sender email, message, page count, and the fax job ID. For team inboxes, only tokens belonging to owner or admin members receive the webhook.
