BitProof Archive

Public web capture with screenshot, HTML, PDF, and Bitcoin proof.

Archive a public page in one evidence bundle.

BitProof timestamps the bundle hash on Bitcoin so anyone can later verify what the page showed.

Works for public posts on X, Reddit, Facebook, LinkedIn, and more. Install Firefox add-on →
Private or app-only content?

For stories, DMs, or in-app feeds, take a screenshot on your phone and timestamp the file instead.
