Quick answers about faxing, signing, 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 ($0.99) — 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 and Canada fax numbers are fully supported. International destinations are not available yet.
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.
Sending a Fax
How do I receive a fax?
The Receive plan ($2.99) gives you a temporary US fax number valid for 24 hours. When a fax arrives, we email you a PDF download link instantly.
Signing PDFs
Is 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.
Signing 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.
Signing 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.
Signing PDFs
Can I delete pages from my PDF?
Yes. In the editor, each page has a delete toggle. Deleted pages are excluded from the final download and fax.
Signing 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.
Credits & Pricing
What are fax credits?
Credits are a pre-paid alternative to per-fax card payments. Each credit sends one fax of up to 15 pages. Credits are cheaper per fax than paying individually and 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 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 and signing work without any account. Signing in (via Google or email) lets you save documents, use credits, manage contacts, and get a dedicated fax number.
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.
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. Busy lines or slow recipient machines can take longer. 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.
