Inspect Image
See what an image says about itself: Content Credentials, IPTC, EXIF, XMP and generator traces, checked separately and explained in plain language.
How SynthOff inspects an image
Content Credentials (C2PA)
Validates signed C2PA manifests with the official SDK and shows the signer, edit actions and any AI-generation claim.
IPTC, EXIF and XMP
Reads the IPTC Digital Source Type, camera and software fields, editing history and generator parameters, and explains what each one means.
Private by design
The file is read inside your browser. Nothing is uploaded, and a strict security policy blocks connections to other servers.
Frequently asked questions
How can I tell if an image is AI-generated?
Inspect Image reads what the file declares: Content Credentials, the IPTC Digital Source Type, editing history and generator parameters. That shows whether a tool marked the image as AI-generated. It can't judge the pixels themselves, and no metadata doesn't prove an image was made without AI.
Why did Facebook label my image “AI info”?
Meta says it looks for industry-standard signals such as C2PA Content Credentials and IPTC metadata, as well as invisible watermarks. Inspect Image lists which of those signals are in your file and explains each one.
What are Content Credentials (C2PA)?
A signed record embedded in the file that describes who made an image and how it was edited, including whether AI was used. SynthOff validates the signature with the official C2PA SDK, in your browser.
Can SynthOff detect SynthID?
Not on your device. Google's SynthID detectors run only on Google's servers. The SynthID section links to Google's official checker, where you can upload the image yourself and record the result.
Is the image uploaded?
No. Every file is processed inside your browser tab. SynthOff has no upload endpoint, and its security policy blocks connections to any other server, so your images never leave your device.
