How to
Remove Content Credentials from a file
Content Credentials are a signed record attached to a file describing how it was made. The standard is C2PA, and you will find these manifests on output from ChatGPT and Sora, on images from Adobe tools, and on files from several cameras. This page covers how to remove one, and, just as importantly, what removing it does and does not achieve.
Removing one
Open the Images tab for a photo, or Files for a PDF or document, drop the
file in, and press Clean. The C2PA manifest is removed as part of a normal clean, along
with XMP provenance fields and any generator tags. You get back
name.cleaned.jpg; your original is never modified.
Check it worked rather than assuming. Drop the cleaned file into the Metadata tab: a file with no manifest reports none. That round trip takes a few seconds and is the only way to actually know.
What removal actually does
A verifier will report the file as having no credential. That is the same state as the overwhelming majority of files on the internet, because most software never writes one. It is not the same as forging a credential that says something untrue, which would need the signer's private key and is not possible by editing the file.
So removal makes a file unremarkable. It does not make it look camera-original to anything doing a serious check.
Reasons people remove them
- The manifest can carry a signer identity you did not mean to publish.
- It can name internal tooling or a workflow you would rather not share.
- It can record an edit history that is nobody else's business.
- On a personal photo it is simply one more block of data travelling to a stranger.
What survives it
If the file came from a generator that also embeds a watermark in the pixels, removing the manifest does nothing to that. Google's SynthID in particular is unaffected by any metadata operation, because it lives in the picture rather than beside it. There is a fuller explanation here.
Content Credentials are also fragile in the other direction: re-encoding an image, screenshotting it, or passing it through software that does not understand C2PA usually discards the manifest without anyone intending to. That fragility is a known property of the design, and it is part of why some vendors pair C2PA with a pixel watermark.
If you want the background rather than the procedure, what a Content Credential actually records covers what is inside a manifest and what it proves.
Common questions
How do I remove C2PA Content Credentials?
Drop the file into the Images tab, or Files for a PDF or document, and press Clean. The C2PA manifest is removed as part of a normal clean, along with XMP provenance and generator tags. Your original file is never modified.
What happens when you remove a Content Credential?
A verifier reports the file as having no credential, which is the same state as most files on the internet. It does not forge a credential saying something untrue, since that would require the signer's private key.
Does removing C2PA remove the AI watermark?
No. If the generator also embedded a watermark in the pixels, such as SynthID, that is unaffected by any metadata operation because it lives in the picture rather than beside it.
