Verificador C2PA

C2PA (Coalition for Content Provenance and Authenticity) is an open technical standard developed by Adobe, Microsoft, Intel, and other major companies. It embeds verifiable information about how digital content was created, edited, and distributed. Content Credentials are the tamper-evident metadata embedded using C2PA standards.

Simply upload your image to our C2PA Checker above. The tool will instantly analyze the file and display any embedded C2PA data, including the claim generator (software used), signature information, creation date, and whether the image was created by AI tools.

Yes! When AI tools that support C2PA (like Adobe Firefly, OpenAI DALL-E, ChatGPT, Google Imagen, or Midjourney) create images, they embed metadata indicating the image was AI-generated. Our checker can detect this and show you exactly which AI tool was used to create the image.

C2PA metadata includes: the claim generator (software that created/edited the image), digital signatures, creation timestamps, action history (what edits were made), ingredient sources (for composite images), and AI generation markers. All this data is cryptographically signed to prevent tampering.

Yes, our C2PA Checker is completely free to use. There are no limits on the number of images you can verify. Simply upload your image and get instant results.

C2PA supports JPEG, PNG, TIFF, WebP images, as well as MP4 and MOV video files. Our checker currently supports image verification. The C2PA data is embedded within the file's binary structure using the JUMBF (JPEG Universal Metadata Box Format) specification.

The absence of C2PA data doesn't automatically mean an image is fake or has been tampered with. It simply means provenance hasn't been recorded using C2PA standards. This could be because the creation tool doesn't support C2PA, the feature was disabled, or the metadata was stripped during sharing.

Yes! Google's Nano Banana image generator embeds C2PA content credentials signed by Google LLC. When you upload a Nano Banana image, our checker instantly identifies the digital source type as trainedAlgorithmicMedia — confirming it was fully AI-generated. You'll also see details like the Google C2PA Core Generator Library version and creation timestamp.

Images generated by Google Gemini (including Gemini Pro and Ultra) include C2PA metadata signed by Google LLC. Simply upload the image here — our C2PA checker will display the issuer, AI tool identification, digital source type (trainedAlgorithmicMedia), actions performed, and the exact signature timestamp. This works for all Gemini-generated images including those from Google Search, Bard, and the Gemini app.

Absolutely! Midjourney now embeds C2PA content credentials in its generated images. Our checker verifies the Midjourney signature and shows the AI generation details. For images without C2PA data (e.g., older Midjourney versions), use our full AI Photo Check which uses 17 forensic detection methods including GAN fingerprinting — specifically designed to detect Midjourney's unique generation patterns.

OpenAI embeds C2PA content credentials in all DALL-E and ChatGPT-generated images. Upload the image to our C2PA checker — it will detect the OpenAI signature, display the AI tool used (DALL-E 3, ChatGPT, etc.), the digital source type, and generation timestamp. If C2PA data was stripped, our full analysis tool can still detect DALL-E images using ML detection and frequency analysis.

trainedAlgorithmicMedia is a C2PA digital source type that means the content was fully generated by an AI model trained on data — such as DALL-E, Midjourney, Stable Diffusion, Google Nano Banana, or Adobe Firefly. When our checker finds this type, it's definitive proof that the image was AI-generated. You may also see compositeWithTrainedAlgorithmicMedia, which means a human-created image was edited or enhanced with AI tools.

Not all AI-generated images contain C2PA metadata — it depends on the generator and platform. Older Midjourney versions, some Stable Diffusion interfaces, and images shared on social media may lack C2PA data. In that case, use our comprehensive AI Photo Check which combines 17 forensic detection methods — including ML detection, PRNU sensor analysis, GAN fingerprinting, texture analysis, and more — to identify AI images even without any metadata.

Yes, some social media platforms (Facebook, Twitter/X, Instagram) strip C2PA metadata when they re-compress uploaded images. For best results, always check the original image file before sharing on social media. If the C2PA data has already been stripped, our full analysis tool can still detect AI generation through 17 independent forensic methods that don't rely on metadata.
