C2PA Lab

> C2PA Lab is a free, privacy-first web tool for inspecting C2PA Content Credentials and digital provenance in images and videos. > C2PA parsing and verification run locally in your browser through WebAssembly — media files are not uploaded to the server for inspection. > The evidence view shows whether the file carries a C2PA credential, the verification status of its manifest and asset binding, the recorded provenance timeline, ingredient references, and signer and issuer information. Everything shown comes from the manifest itself, never inferred from file names or heuristics. > Developers get a dedicated Manifest Viewer that exposes the raw manifest store, active manifest, claims, assertions, and JSON, plus a Metadata Inspector that lays out signer identities, timestamps, recorded actions, and source disclosures in a structured table. Any inspection result can also be exported as a locally rendered Proof Card — a 1200×630 PNG summary. > The site's Guides section covers what C2PA and Content Credentials are, how to check them, how verification works, camera support, and how C2PA compares to watermarking approaches like SynthID — always with an honest account of what credentials can and cannot prove. > Supported formats include JPEG, PNG, WebP, AVIF, MP4, and MOV. All tools are free to use, with no ads and no signup required.
