Web-based tools

Content Credentials Verify

FreeWeb

The official verification tool maintained by the Content Authenticity Initiative. Upload any file or paste a URL, and it displays the complete Content Credentials chain - signer, tool, timestamp, edit history, and trust validation. This is the standard reference implementation and the tool most commonly linked by news organisations and platforms.

Strengths

Most complete credential display. Validates against the official C2PA Trust List. Supports images, video, audio, and documents. URL-based verification (no download needed for public content).

Limitations

Processes files client-side (slower on large videos). No batch processing. Can't sign content - verification only.

C2PA Viewer

FreeWeb

An independent web tool focused on manifest inspection. While the official Verify site presents credentials in a polished, consumer-friendly format, C2PA Viewer exposes the raw manifest data - including JSON output and detailed assertion breakdowns. Particularly useful for developers, researchers, and anyone who wants to see the full technical detail.

Strengths

Raw manifest JSON display. Detailed assertion-level breakdown. WebAssembly processing (files stay in browser). Published articles and guides alongside the tool.

Limitations

Less polished UI than official Verify. Uses interim trust list - may show different trust results than official tool.

Adobe Content Authenticity (Beta)

FreeWeb

Adobe's standalone web app for Content Credentials. Unlike the other tools listed here, Adobe Content Authenticity can both inspect and attach credentials. Creators can upload finished work and sign it with their Adobe identity, even if the work was created in non-Adobe software. Also includes the Inspect function for verification.

Strengths

Both verify and sign. Connect social accounts for identity verification. Works with art from any software. Clean, creator-focused interface.

Limitations

Requires Adobe account. Currently in beta - features may change. Signing uses Adobe's certificate (not your own).

New tools and updates

We update this page when new verification tools launch or existing ones change significantly.

Browser extensions

Digimarc Content Credentials Extension

FreeChrome Extension

A Chrome extension that automatically checks images on web pages for C2PA manifests as you browse. When an image has Content Credentials, the extension overlays the "CR" icon. Click it to view the credential details without leaving the page. Built on the open-source c2pa-js library.

Strengths

Passive verification - works as you browse. No upload needed. Shows credentials in context. Open source (GitHub).

Limitations

Chrome only (no Firefox, Safari, Edge). Can only check images served with C2PA data intact - most platforms strip it. Performance impact on image-heavy pages.

→ Available on the Chrome Web Store (search "Digimarc Content Credentials")

Developer tools

c2patool (CLI)

Free / Open SourceCLI

The official command-line tool from the Content Authenticity Initiative, built on the c2pa-rs Rust library. Can read, validate, and create C2PA manifests. The most powerful tool for developers and anyone comfortable with the terminal. Supports batch processing, JSON output, and custom manifest creation.

Strengths

Full read and write capability. Batch processing. Scriptable (JSON output). Cross-platform (macOS, Windows, Linux). Reference implementation - always up to date with the spec.

Limitations

Requires terminal comfort. No GUI. Signing requires a certificate (test certs included for development).

c2pa-js

Free / Open SourceJavaScript

The JavaScript/WebAssembly SDK for reading C2PA manifests in the browser. If you're building a web application that needs to verify Content Credentials client-side (no server upload), this is the library. Powers the Verify site, C2PA Viewer, and the Digimarc extension.

Strengths

Client-side processing (privacy - files don't leave the browser). Well-documented API. Active development. Powers the major web verification tools.

Limitations

Read-only (no signing in browser). WebAssembly bundle adds to page weight. Some advanced validation requires server-side processing.

Enterprise and platform tools

PixelStream

Platform

A commercial end-to-end C2PA platform. PixelStream handles the full lifecycle - capture, signing, editing, distribution via CDN, and display to end users. Aimed at enterprises and media organisations that need a managed solution rather than building on the open-source SDKs themselves.

Strengths

Full lifecycle management. CDN with credential preservation. Enterprise support. Simplifies the credential-stripping problem for web distribution.

Limitations

Commercial pricing. Lock-in risk with proprietary distribution layer. Overkill for simple use cases.

Which tool should you use?

If you just want to check a single image: Content Credentials Verify. Upload the file, get the result. Done.

If you want to see the raw technical data: C2PA Viewer. It shows the full manifest JSON and assertion details that the official tool summarises.

If you're a creator who wants to sign your work: Adobe Content Authenticity (Beta). It's the only free web tool that both inspects and signs.

If you want passive verification while browsing: Digimarc Chrome Extension. Install it and forget about it - it checks automatically.

If you're a developer integrating verification: c2pa-js for browser-based apps, c2patool for server-side or CLI use, the SDKs (c2pa-rs, c2pa-node, c2pa-python) for application integration.

If you're an enterprise building a full content authenticity pipeline: Start with the open-source SDKs. Evaluate PixelStream if you need managed infrastructure. See our Developer Guide for implementation details or our consulting services for hands-on help.
