Watermark Remover
Remove watermarks from images in your browser. Auto-detects and losslessly reverses Gemini-style AI watermarks; brush over any other watermark to erase it. No upload — 100% private.
Watermark Remover is a free browser-based tool that erases visible watermarks from images. It losslessly reverses known semi-transparent AI watermarks (such as Gemini's) using exact math, and repairs any other watermark you brush over — entirely on your device, with no upload.
What is a watermark remover?
A watermark remover erases logos, text overlays, or stamps from an image. This tool uses two techniques: exact reverse alpha blending for known watermark patterns (pixel-perfect on PNG), and inpainting — reconstructing hidden pixels from their surroundings — for everything else. After a one-time model download, brush repairs use the MI-GAN neural network for realistic results on complex backgrounds.
How to remove a watermark
- 1
Upload an image
Drop or select an image. Known watermarks (e.g. Gemini) are detected and removed automatically and losslessly.
- 2
Brush over the watermark
If no known pattern is found, paint over the watermark with the brush. Use undo or the eraser to refine your selection.

Remove and download
Click Remove watermark. Enable AI Enhance once to download the model — after that, removal automatically uses the MI-GAN neural network. Download the result as PNG (lossless), JPEG, or WebP.
