How does the Gemini Watermark Remover work?

The tool uses reverse alpha blending, a mathematical method to restore the original pixel values. Since the Gemini watermark is a semi-transparent white logo, the original color can be calculated.

Are my images uploaded to a server?

No, all images are processed 100% locally in your browser. No image data leaves your device. The tool only requires a brief connection for usage verification.

Are invisible watermarks (SynthID) also removed?

No, this tool only removes the visible Gemini watermark. Invisible watermarks (SynthID) remain in the image and cannot be removed. SynthID is a watermark developed by Google DeepMind that is embedded in the image data and is not visible to the human eye.

Which image formats are supported?

The tool supports PNG, JPG, JPEG and WebP. The maximum file size is 10 MB per image.

Why does my image look slightly different after processing?

In areas where the watermark was very strong, the reconstruction cannot be perfect. This is because information is irretrievably lost at high transparency levels.
