How it works
- 1
Load an image generated by Google Gemini that shows the logo watermark in the bottom-right corner.
- 2
Click Remove watermark. The tool detects the watermark profile and reverses the alpha blend to restore the pixels underneath.
- 3
Download the clean image. If no watermark is detected you’ll be told instead of getting a silently altered file.
Frequently asked questions
Are my images uploaded to a server?
No. Every tool on this site runs entirely in your browser using the HTML canvas. Your images never leave your device, which also makes processing instant — there is no upload or download wait.
How does it work?
Gemini composites its logo over the image with known transparency values. Using calibrated alpha maps of that overlay, the original pixel values are recovered by reversing the blend equation — no AI inpainting, no invented pixels.
Does it remove the invisible SynthID watermark?
No. Only the visible corner logo is removed. Google’s invisible SynthID marking, which identifies AI-generated content, remains intact.
Why does it say no watermark was found?
The image may have been cropped, resized, or re-compressed since generation, which shifts the watermark off its known position, or it may not be a watermarked Gemini image at all.
