AI watermark checker
This checks the metadata layer: C2PA manifests, XMP generation tags, PNG text and AI related EXIF. If a marker is there, you will see the field and its value.
It does not detect invisible pixel watermarks, and this page explains why no metadata tool can.

Two different things
Metadata markers versus pixel watermarks
| Metadata markers | Pixel watermarks | |
|---|---|---|
| Where it lives | Container blocks beside the image | Inside the pixel values |
| Examples | C2PA, XMP tags, PNG text | SynthID and similar schemes |
| Survives a screenshot | No | Designed to |
| Survives recompression | Usually not | Designed to |
| Can we detect it | Yes | No |
| Can anyone remove it | Yes, cleanly | Not without damaging the image |
Pixel watermarks are embedded as tiny statistical adjustments across the image. Detecting them requires the detector that matches the scheme, and those are not generally public. Removing them means altering pixels, which this tool deliberately never does.
Be sceptical of removal claims
Any tool advertising invisible watermark removal is either heavily re-encoding your image and hoping the signal breaks, or overstating what it does. Neither is worth the quality you would pay for it.
What to conclude
Reading a clean result honestly
- Markers found. The file declares AI involvement. Removing them addresses most platform labels.
- Nothing found. The metadata layer is clean. That is not proof the image is not AI generated, and not proof no watermark exists.
- Still labelled after cleaning. The cause is visual: a classifier, or a pixel watermark. No metadata tool changes that outcome.
Questions
Frequently asked questions
›Can you detect SynthID?
No. SynthID is embedded in pixel values and detecting it requires Google's own detector. We check the metadata layer and say so plainly rather than guessing.
›Can you remove an invisible watermark?
No, and we would not want to claim it. Removing a pixel watermark means altering pixels, which is the one thing this tool is designed never to do.
›Then what is this checker for?
Finding out whether your file carries metadata markers, which is what most platform labels actually read. It answers that question precisely instead of answering a harder question vaguely.
›If nothing is found, is my image safe to post?
The metadata layer is clean. Whether a platform labels it also depends on visual classification, which no file inspection can predict.
