Is this watermark remover free?

Yes. The tool is completely free with no sign-up, no watermarks added, and no usage limits. There is nothing to install.

Are my images uploaded to a server?

No. All processing happens locally inside your web browser using JavaScript. Your images never leave your device, which keeps them completely private.

What kind of watermark can it remove?

It is designed for the semi-transparent Gemini AI watermark that appears in the bottom-right corner of Google Gemini generated images. It uses a mathematically exact reverse alpha-blending method rather than AI guesswork, so the result is lossless on supported images.

Which image formats are supported?

You can upload PNG, JPEG, and WebP images. The cleaned image is provided as a PNG download.

Does removing the watermark reduce image quality?

No. The tool reverses the exact alpha blending Gemini used to apply the watermark, restoring the original pixels. Only the watermarked region is touched and the rest of the image is untouched.
