Document check

Verify a Pakto document

Attach a signed contract or a PDF with photo evidence (or its tmark.json). Pakto re-checks the ECDSA signatures, content hashes and the integrity of embedded photos right in your browser — nothing is uploaded.

Drop a PDF or JSON here

or click to choose — .pdf, .json

The file never leaves your device — it is read and verified locally in your browser. Nothing is uploaded to our servers.
