Verify Document

Check document authenticity and integrity

Verify a PDF — confirm a document is authentic

Check whether a signed PDF is genuine and unaltered. Upload a file or enter a verification code to confirm authenticity against the original. Free for everyone.

How does PDF verification work?

Every document signed on VersoPDF gets a SHA-512 hash and a verification code. We re-hash your uploaded file and compare it to the original to confirm it wasn't altered.

Is verification free?

Yes. Verifying a document by file or code is free for everyone, including recipients without an account.
