What watermarks can be removed?

This tool removes the visible watermark in the bottom-right corner of images generated by Google Gemini (Nano Banana). Both 48x48 and 96x96 watermark sizes are supported. Invisible watermarks like SynthID cannot be removed with this tool.

Are images sent to a server?

No. All image processing happens 100% in your browser. Images are never sent to or stored on a server. The tool works without an internet connection (after the page loads).

What is the removal quality?

Because we use Reverse Alpha Blending mathematical inverse operations, theoretically 100% lossless restoration is possible. Unlike AI inpainting, we recover original pixels through precise calculation, not guesswork.

Can I process multiple images at once?

Yes, you can drag & drop multiple images simultaneously or select multiple files at once. All images are processed sequentially, and you can save them all at once with the Download All button.

What image formats are supported?

You can upload JPEG, PNG, and WebP format images. Results can be downloaded in PNG (lossless) or JPEG format.

Is watermark removal legal?

This tool is intended for removing watermarks from AI images you have generated yourself. Removing watermarks from others' copyrighted works may violate copyright law. Please use at your own legal responsibility.
