Verify

Is this the document that was signed?

Upload a PDF you received from Accordify. We check its cryptographic seal. Any change after signing, even one character, makes verification fail.

  1. 01

    Upload the PDF

    It is checked in memory and never stored.

  2. 02

    We check the seal

    PAdES signature, whole-file coverage and the RFC 3161 trusted timestamp.

  3. 03

    We compare to our records

    The hash must match the sealed envelope on the Accordify ledger.

No account needed. Verification is free.
