Sometimes a plain PDF needs to look and feel like an official copy before you hand it over - a signed offer letter, a certificate, a report going to a client. This tool adds page numbers, a footer with your organization name and the date, an optional new cover page, and an optional QR verification stamp - all drawn directly onto the document. The QR stamp is described honestly here for exactly what it is: a self-contained fingerprint of the file (its own SHA-256 hash, computed the moment it's stamped, and printed under the QR too), not a connection to any database or lookup service, and not a legal notarization or certification. Anyone who wants to confirm the document hasn't changed since it was stamped can re-hash their own copy of the original file and compare it to the value printed under the QR - no account or lookup needed on either end.
How to use this tool
- Choose what to add - page numbers, a footer, a date stamp, a QR verification stamp, and/or a new cover page.
- Fill in an organization name, a cover title, and a reference ID if you want one (leave the reference ID blank and one is generated automatically).
- Drop in your PDF, sign in, and download the stamped copy.
Frequently asked questions
Is the QR stamp a legal notarization?
No - this tool never claims that, and it's worth being direct about it: the QR stamp is a plain, self-contained tamper-evidence fingerprint of the file's own bytes at the moment it was stamped, not a notarization, certification, or a connection to any lookup service. Treat it as a way to let someone confirm a copy hasn't been altered since it was stamped, nothing more.
How does someone actually verify the QR stamp?
They scan it (or read the SHA-256 hash printed underneath it) and compare it against a fresh hash of their own copy of the ORIGINAL, unstamped file - entirely offline, with no account or database on this site involved. If the hashes match, that copy of the original file is identical to the one that was stamped.
Is stamping a document free?
Your first stamp on this site is free. After that it's a flat, small credit charge per document - there's no separate free "scan" step for this tool since there's nothing to scan for; you're choosing what to add, not fixing something that was found.
