A real Gemini watermark, removed by this tool. Drag the slider to compare.
This exact before/after pair was produced by the engine running in this site — no retouching.
How it works
Three steps, entirely in your browser.
Upload an image
Choose or drag in a Gemini-generated JPG, PNG, or WebP image.
Auto-detect and remove
The engine matches known Gemini output sizes, locates the watermark, and reverses the alpha blend that produced it.
Download the clean image
Compare before/after with the slider, then copy or download the restored file.
Built for Gemini's visible watermark
A mathematical approach, not a guess.
Lossless restoration
Uses reverse alpha blending to solve for the original pixel values instead of AI inpainting — the result is exact, not guessed.
Runs entirely on-device
Nothing leaves your browser. There is no upload step and no server processing your images.
Automatic detection
Matches your image against known Gemini output dimensions to predict watermark size and position automatically.
Batch support
Select multiple images at once and process them together with the same one-click workflow.
Video support
Gemini and Veo 3 video watermarks are supported too — see the video tool.
Open pipeline
The detection and restoration engine is open source, based on the original Reverse Alpha Blending research.
FAQ
Common questions about removing Gemini watermarks.
Does this upload my images anywhere?
No. Every step — decoding, detection, and restoration — runs locally in your browser tab.
Will this work on any watermarked image?
It targets Gemini's visible bottom-right watermark on known output sizes. Unsupported sizes or watermark styles may be skipped rather than guessed at.
Does it remove SynthID or other invisible watermarks?
No — this only removes the visible logo overlay. Invisible/steganographic watermarking is a separate mechanism this tool does not touch.
Is it really free?
Yes. The processing engine is open source and runs on your device, so there's no per-image cost.
