About

C2PA Lab is a free online inspector for C2PA Content Credentials and digital provenance. C2PA parsing and verification run locally in your browser through WebAssembly, so media files are not uploaded for inspection. See verification state, the provenance timeline, ingredient references, and signer and issuer details as recorded in the manifest. A dedicated Manifest Viewer exposes the manifest store, claims, assertions, and JSON for developers, while the Metadata Inspector presents selected fields in a structured table. A Proof Card can be rendered locally as a shareable 1200×630 PNG summary. Nine practical guides explain C2PA, Content Credentials, verification, camera support, and watermarking. Supports JPEG, PNG, WebP, AVIF, MP4, and MOV. Free, no ads, no signup.
