Verification
Verify a signed document
Add the signed PDF and we’ll confirm whether it is authentic and unchanged since it was signed. No account needed, and nothing to type.
Your document is never uploaded.
Verification happens entirely in your browser. Your PDF is fingerprinted on your own device and only that fingerprint — never the file, and never its contents — is sent to us.

That’s all we need — the file identifies itself.
Have a verification code instead?
A code on its own confirms a document was signed. It cannot confirm that any particular file is the unaltered one — only the PDF can do that.
