Prove any document is real — forever
Upload a document and it's sealed with a tamper-proof fingerprint and timestamp. Share a link or QR code — anyone can confirm it's authentic and unaltered, free, in seconds.
How it works
1 · Upload
Sign in and upload a document with a short description. It's stored encrypted — only you and people you share with can see it.
2 · Seal
We record a tamper-proof fingerprint and exact timestamp — a permanent proof the file existed, unchanged, at that moment.
3 · Verify
Share the link or QR code. Anyone can confirm it's authentic and unaltered — instantly, and always free.
Under the hood
Each document is fingerprinted with SHA-256 and the file is kept in encrypted storage. The fingerprint and timestamp are written to a permanent verification registry, so the proof stands on its own and can be checked by anyone, forever — without exposing the file itself.
