C2PA REPORT AREA
Content Credentials Results
After uploading a file, mdremove shows whether Content Credentials were found and summarizes the manifest, validation status, source signals, actions and ingredients.
What mdremove checks in a C2PA file
C2PA is not the same as ordinary EXIF metadata. It is provenance data designed to show who signed a file, what tool touched it, and whether signed information still validates.
Validation signals
Review valid, warning, issue or unavailable states in plain language so the result is easier to understand.
AI source declaration
Check whether the file declares an AI-related source type or generator inside Content Credentials.
Actions and ingredients
Inspect recorded edits, exports and source materials when this information exists in the manifest.
How to read the result
Use the result as a provenance signal, not as a final truth test. A file can be authentic without C2PA, and a signed file still needs context.
| Status | Meaning inside mdremove |
|---|---|
| Verified credentials found | A manifest was found and no blocking validation issue was returned by the verifier. |
| Credentials with issues | The file contains C2PA data, but the report includes warnings, invalid data, missing trust details or other problems. |
| No Content Credentials | No readable C2PA manifest was found. This does not prove the file is fake. |
| Marker found | The file contains C2PA/JUMBF markers, but the manifest could not be fully verified in the current check. |
Useful for publishers, creators and teams
mdremove helps you quickly inspect provenance before publishing, archiving, approving or sharing a sensitive file.
Newsrooms
Check whether a photo or document includes a provenance trail before it enters an editorial workflow.
Brands
Review creator, tool and edit signals before approving campaign assets or public media.
Photographers
Inspect signed capture or export information when sharing original work with clients or platforms.
AI review
Look for AI-related source declarations when a file includes Content Credentials from supported tools.
Supported C2PA file types
You can try common file types that may carry Content Credentials. Support depends on whether the creator tool actually embedded a C2PA manifest.
Images
JPG, JPEG, PNG, WEBP, GIF, TIFF, TIF, HEIC, HEIF, AVIF, SVG
Documents
PDF and other files may expose C2PA data when signed by compatible software.
Video
MP4, MOV, M4V and WEBM can be tested for provenance metadata.
Audio
MP3, WAV and M4A can be checked when provenance data is present.
C2PA Viewer FAQ
Answers written for mdremove users who want to understand Content Credentials without technical confusion.
What can mdremove C2PA Viewer check?
It checks whether Content Credentials exist, then shows readable details such as manifest status, source declarations, signer/generator signals, actions, ingredients and a JSON report.
Why does a file show no Content Credentials?
The file may have been created without C2PA data, exported by unsupported software, compressed by another app or shared through a platform that removed metadata.
Can C2PA tell if an image is AI-generated?
Only when the file contains a relevant source declaration or generator information. If there is no manifest, C2PA alone cannot confirm whether an image was AI-generated.
Can EXIF and C2PA show different things?
Yes. EXIF usually stores camera and technical fields, while C2PA focuses on signed provenance. A file can have EXIF without C2PA, C2PA without useful EXIF, both, or neither.
Should I trust a file only because it has C2PA?
No. C2PA is helpful evidence, but it should be combined with source checks, context, visual review and editorial judgment.
