C2PA Supported Devices & Software: Complete Reference
Every camera, smartphone, AI generation tool, and editing application that supports C2PA Content Credentials, with signer types and verification details.
This page is a living reference of every device and application that signs content with C2PA Content Credentials. When you verify an image with any of these signers, the AttestTrail API returns a deterministic decision class based on the signer type.

Cameras
Camera-level C2PA signing provides the verified_camera_origin decision class -- cryptographic proof that a physical device captured the image. For technical details on how hardware signing works, see C2PA Cameras & Phones 2026.
| Manufacturer | Models | Secure Element | C2PA Since |
|---|---|---|---|
| Leica | M11-P, M11, Q3, SL3 | Firmware-integrated | October 2023 (M11-P) |
| Nikon | Z9, Z8, Zf | Secure Processing Unit (SPU) | 2024 (firmware update) |
| Canon | EOS R1, EOS R5 Mark II | Hardware secure element | 2024 |
| Sony | a9 III, a1 | Tamper-resistant element | 2024 (firmware update) |
All camera manufacturers listed above have certificates that chain through the Content Authenticity Initiative's trust infrastructure.
Smartphones
Smartphone C2PA signing also produces the verified_camera_origin decision class, using the same hardware security model as dedicated cameras.
| Manufacturer | Models | Secure Element | C2PA Since |
|---|---|---|---|
| Samsung | Galaxy S25 series | Qualcomm Snapdragon 8 Elite SPU | Early 2025 |
| Pixel | Tensor security core / Qualcomm SE | 2025 |
Smartphone C2PA is currently limited to flagship devices. Mid-range and budget models from these manufacturers do not yet support C2PA signing.
AI Generation Tools
AI tool signing produces the verified_synthetic decision class -- cryptographic proof that the image was generated by an AI model. This is the primary signal for EU AI Act Article 50 compliance.
| Provider | Products | Digital Source Type | C2PA Since |
|---|---|---|---|
| Adobe | Firefly, Photoshop (generative fill) | trainedAlgorithmicMedia | 2023 |
| OpenAI | DALL-E 3, ChatGPT image generation | trainedAlgorithmicMedia | 2024 |
| Imagen, Veo | trainedAlgorithmicMedia | 2024 | |
| Microsoft | Copilot image generation, Bing Image Creator | trainedAlgorithmicMedia | 2024 |
These providers sign every generated image with C2PA manifests. The trainedAlgorithmicMedia IPTC digital source type assertion explicitly marks the content as AI-generated.
Editing Software
Editing software that supports C2PA preserves the provenance chain when modifying signed images. The original manifest becomes an ingredient in the new manifest, maintaining the full editing history.
| Application | C2PA Capability | Notes |
|---|---|---|
| Adobe Photoshop | Creates new manifests with ingredient references | Full action recording (crop, color, retouch, generative fill) |
| Adobe Lightroom | Creates new manifests with ingredient references | Non-destructive editing actions recorded |
| Adobe Premiere Pro | Video manifest support | Extends C2PA to video editing workflows |
Applications that do not support C2PA -- including Affinity Photo, GIMP, Capture One, and most mobile editors -- will strip C2PA manifests when saving. The provenance chain breaks at that point. See what happens when you edit a camera-signed image for mitigation strategies.
Platforms Preserving C2PA
A growing number of platforms preserve or display C2PA Content Credentials on uploaded content, rather than stripping them during processing.
| Platform | Capability |
|---|---|
| Preserves and displays Content Credentials on uploaded images | |
| Truepic | Full C2PA verification and credential display |
| Cloudflare Images | Preserves C2PA manifests through image processing pipeline |
Most social media platforms (Instagram, X, TikTok, Facebook) still strip C2PA metadata during re-encoding. This is the largest ecosystem gap. Perceptual fingerprint matching can recover original provenance for stripped images.
Verification Tools
| Tool | Type | Cost |
|---|---|---|
| AttestTrail API | REST API with trust list, fingerprint recovery, decision classes | Free tier + $0.01/request |
| AttestTrail C2PA Viewer | Web-based verification tool | Free |
| c2patool | CLI tool from Content Authenticity Initiative | Free (open source) |
| Adobe Content Credentials | Web-based viewer at contentcredentials.org | Free |
How to verify any supported device
Upload an image from any device or tool listed above to the C2PA Viewer to see its full provenance report. For programmatic verification in your own application, use the AttestTrail API.
The API returns a structured report including:
- •
decision_class--verified_camera_origin,verified_synthetic,unverified_high_risk, orunverified_low_risk - •Signer identity -- the organization and certificate behind the signature
- •Trust status -- whether the signer is on the curated trust list
- •Credential chain -- the full provenance history including ingredients
