Frequently Asked Questions
Learn more about Gemini Watermark Remover technology and safety
How does this Watermark Remover work?
Unlike generic AI inpainting tools that guess what's behind a watermark, our tool uses a specific mathematical approach called 'Reverse Alpha Blending'. Since we know the exact pixel values of the Gemini watermark pattern, we can mathematically subtract it from the image to restore the original pixel colors with high precision.
Is it safe / private?
Yes, absolutely. The tool runs completely within your web browser. Your images are processed locally on your device and are never uploaded to our servers or any third party. You can even disconnect your internet after loading the page and it will still work.
Is it really free?
Yes, this tool is 100% free to use. It is an open-source initiative designed for educational purposes and to help the community.
Does it reduce image quality?
No. The removal process is lossless for the non-watermarked areas. For the watermarked areas, it restores the original colors as mathematically close as possible, avoiding the blurriness often seen with other AI removal tools.
Which image formats are supported?
We support all common web image formats including JPG, PNG, and WebP. The tool automatically detects the format and processes it accordingly.
