About FaxSeal
FaxSeal is an internet fax service built for moments that matter — sending a document to a doctor's office, court, insurer, government agency, or employer, and being able to prove it arrived.
What we do
Most fax services hand you a confirmation and move on. FaxSeal generates a Certified Delivery Receipt — a cryptographically linked record that ties your exact document (via SHA-256 hash) to a carrier-confirmed delivery timestamp. It's verifiable, tamper-evident, and permanently accessible via a public URL.
No account is required to send a fax. Pay per transmission. No subscription, no monthly fees, no lock-in.
Who we are
FaxSeal is an independent software company based in Santa Clara, Utah. We're a small team focused on making fax delivery reliable, transparent, and provable for individuals, small businesses, and professionals who need documentation they can stand behind.
We use SignalWire for fax transmission, Stripe for payments, and Cloudflare R2 (US infrastructure) for encrypted document storage. We don't read your documents, sell your data, or run ads.
