How to Verify a PDF Document
To verify a PDF you need a way to confirm it is genuine and has not been changed since it was finalised. If the PDF was sealed by PDF Verified, its SHA-256 fingerprint and a QR code are embedded, so verification is instant. For any other PDF, upload it and the forensic checker inspects its structure, metadata and revision history to give you a verdict.
Step by step
- Open the free checker at /verify.
- Scan the QR code on the document, or paste its short verification code.
- No code? Upload the PDF file directly.
- Read the verdict — authentic, modified, expired, revoked, or unsigned — and open the audit trail if available.
What to look for
- An embedded SHA-256 fingerprint that still matches the file
- A QR code and short code that resolve to a public verification page
- A clean revision history with no edits after signing
- Intact metadata consistent with the producer software
Frequently asked questions
Is it free to verify a pdf?
Yes. Upload the PDF to the PDF Verified checker and get a verdict for free — no account needed. The file is analysed and not shared.
Do I need the original to compare against?
No. If the document was sealed by PDF Verified, the SHA-256 fingerprint is embedded and checked automatically. For any other PDF, the forensic checker inspects the file's own structure, metadata, and revision history.
Is my document kept private?
The file is processed only to produce the verdict and is not published or shared. Verification of a PDF Verified document can also be done with just the QR code or short code — without uploading the file at all.
How do I get a PDF verified?
Sign or seal the PDF in PDF Verified — it embeds a SHA-256 fingerprint, a QR code and a public verification link automatically. Anyone can then verify it for free by scanning the code or uploading the file at /verify.
How do you verify a PDF is genuine?
Scan its QR code or upload it at /verify. PDF Verified checks the document’s fingerprint and structure and returns a clear authentic-or-altered verdict, with an audit trail where available.
