What VeriPDF does today
One native binary that renders, annotates, seals, and verifies — entirely on your machine. Everything below ships in the current build unless it carries a coming soon chip.
VeriPDF 1.1 · early access · Windows / macOS / Linux
01 / audit trail
A sealed PDF proves its own history
Sealing starts a hash chain inside the document: every entry records the fingerprint of the state before it, signed with Ed25519 on your device. The file carries its own evidence — no server holds the truth for you.
