A free tool to inspect C2PA Content Credentials, provenance, digital signatures and recorded actions directly in your browser without uploading files.

Overview

The C2PA Lab homepage

C2PA Lab is an independent browser-based tool for checking C2PA Content Credentials and understanding digital provenance. It lets users inspect manifests, verify signatures, and review provenance timelines and ingredients directly in their browser using WebAssembly, with no file uploads. The tool supports images, videos, audio files and PDFs up to 200 MB. It helps ordinary people read what credentials say and helps developers inspect underlying manifest data. C2PA Lab reports evidence rather than verdicts: a verified signature proves the manifest is intact and bound to the file, but does not prove every recorded claim is true or detect unrecorded edits.

Buyer questions

What is C2PA?

C2PA (Coalition for Content Provenance and Authenticity) defines an open technical standard for attaching cryptographically signed provenance data to media files.

What are Content Credentials?

Content Credentials are the user-facing expression of C2PA provenance data: recorded actions, ingredients, and signer information embedded in a file.

Does C2PA prove that a file is authentic?

No. A verified signature proves the manifest is intact and bound to the file. It does not prove every recorded claim is true, and it cannot detect unrecorded edits.

Does C2PA Lab upload my files?

No. Inspection runs entirely in your browser using WebAssembly. File contents never leave your device, and analytics records only non-sensitive inspection metadata such as a coarse file class or result status.

Which file types are supported?

JPEG, PNG, WebP, AVIF, HEIC/HEIF, SVG, MP4, MOV, MP3, WAV, and PDF files up to 200 MB are supported after format-specific validation in modern browsers.
