C2PA Viewer is a free online tool for viewing and verifying C2PA Content Credentials, positioned as a way to check provenance credentials for digital images and videos. Users can upload files, paste a URL, or drag in up to 10 files at once for batch inspection. The site emphasizes that files are processed in the browser via WebAssembly, with no server uploads, no tracking, and no account required.
Functionally, it not only reports the C2PA verification status, but can also display the full Manifest output and raw JSON, including information such as the signer, certificate chain, software usage records, AI-generated labels, action history, and timestamps. The main page states that the web tool supports JPEG, PNG, TIFF, WebP, MP4, and MOV, and the homepage also mentions a maximum single-file size of 500MB. Compared with the more consumer-oriented verify.contentauthenticity.org, C2PA Viewer stands out by providing the Raw Manifest, making it more suitable for technical analysis, debugging, and fact-checking.
In terms of pricing, the pages repeatedly state that it is free, requires no account, and has no cost; there is no paid plan or enterprise edition mentioned. As for the ecosystem, it is built around the C2PA standard. The documentation lists devices and platforms that support C2PA or SynthID, including Adobe, Google, OpenAI, Sony, Leica, Nikon, YouTube, LinkedIn, and Cloudinary, and presents c2patool CLI, browser extensions, and the official Content Authenticity verification site as complementary tools. The site itself does not disclose any API, SDK, self-hosting, or open-source information.
Its strengths are a low barrier to use, clear privacy-oriented design, no installation or login requirement, and the ability to inspect raw JSON, making it useful for developers, journalists, content moderation, and provenance research. The documentation is also solid, covering C2PA concepts, the verification process, metadata inspection, and the limitations of the standard. The drawbacks are also clear: it can only verify an existing C2PA Manifest and cannot prove that the content itself is true; the absence of C2PA data does not mean a file is fake; the web version supports fewer formats than c2patool CLI; and there is no information about team collaboration, APIs, or commercial support.
It is well suited to news editors, fact-checkers, developers, and content safety teams that need to quickly verify the provenance of images or videos. It is also useful for users learning about the C2PA standard. The source text does not provide information about access from China, so it is not possible to determine whether it can be reached directly. Payment is not an issue, since current information indicates that it is free. If access is restricted, local c2patool CLI or other C2PA verification tools can be considered as alternatives.
