Is this for removing other people’s watermarks?
No. It is meant for images you generated or own. Removing a watermark from someone else’s work can infringe their rights.

AI Watermark Remover (Experimental)
AI Watermark Remover is an experimental browser tool for images you created with AI generators. It can rebuild a whole image to test against invisible watermarks from GPT-image or Nano Banana, restore the visible Gemini sparkle mark, repair small marked areas with local inpainting and strip metadata. Everything runs on your device, and removal of invisible watermarks is not verified.
What it does
- Experimental whole-image reconstruction with adjustable strength and resolution
- Restoration of the visible Gemini sparkle mark
- Local AI inpainting for small marked areas
- Metadata cleaning
- Device, timing, PSNR and before/after comparison
- Export as WebP at the original dimensions
How to use it
-
Step 1
Upload a PNG, JPG or WebP image and choose the processing mode.
-
Step 2
Choose GPU or CPU, the working resolution and the strength, then run it.
-
Step 3
Compare the result with the original and check the quality figures, then export WebP.
Limits and notes
- Up to 25 MB, 12 megapixels and 8192 px per side.
- The first reconstruction downloads about 32 MB; local inpainting about 40.8 MB.
- An inpainting selection must cover less than 25% of the image.
- Reconstruction changes fine detail. There is no detector, so removal of SynthID or other invisible watermarks cannot be confirmed.
- Metadata cleaning does not remove watermarks that are part of the pixels.
Privacy
Images stay on your device. Processing uses your browser’s WebGPU or CPU; there is no server and no API key.
Questions
Does it really remove SynthID?
That is not verified. The tool has no SynthID detector, and the PSNR value only measures how much the pixels changed.
Can it use my GPU?
Yes, through WebGPU in supported browsers, with automatic fallback to the CPU.
