Yes, completely free. No signup, no login, no usage limits - forever. The tool runs entirely in your browser, so there are no server costs to pass on to users.

Does it work with Nano Banana (Google AI Studio) images?

Yes. This tool removes the Gemini sparkle watermark from all Gemini-generated images, including those made via Nano Banana, Nano Banana Pro, and Google AI Studio.

Are my images uploaded to a server?

No. All processing happens 100% in your browser using Web Workers technology. Your images never leave your device. You can verify this by opening Chrome DevTools -> Network tab and confirming zero image data is sent to any server.

Is the watermark removal lossless?

Yes. The tool uses reverse alpha blending - the mathematically exact inverse of how Gemini applied the watermark - to restore the original pixels precisely. Only the watermark area is touched. The rest of the image is pixel-perfect.

Does removing the Gemini watermark also remove SynthID?

No. This tool removes the visible sparkle watermark only. The invisible SynthID watermark embedded in pixel values by Google DeepMind is not affected and cannot be removed without degrading image quality.

What image formats are supported?

The tool accepts PNG, JPG (JPEG), and WebP images up to 20MB. Gemini images are typically downloaded as PNG or JPG - both work perfectly. The output is always a clean PNG for lossless quality.

What is the Gemini sparkle watermark (✦)?

The Gemini sparkle watermark is a small four-pointed star symbol (✦) that Google automatically adds to the bottom-right corner of every image generated by Gemini, Nano Banana, or Google AI Studio. It signals that the image was created by Google AI. It appears on Free and Pro tier images; Google AI Ultra subscribers get watermark-free images by default.

Can I remove the Gemini watermark on mobile (iPhone or Android)?

Yes. This tool works in any modern mobile browser - Chrome, Safari, Firefox, Edge. Open the tool on your phone, upload your Gemini image, and download the clean version. No app installation required.

Is it legal to remove the Gemini watermark?

Under Google's terms of service, you retain rights to use images you generate with Gemini for personal and commercial purposes. Removing the visible sparkle watermark from images you generated is generally acceptable. The invisible SynthID watermark remains intact, which continues to identify the image's AI origin. Always review Google's current Terms of Service for your specific use case.

Why do Gemini images have a watermark?

Google adds the sparkle watermark as part of its AI transparency commitment. According to Google's official policy: "In addition to SynthID, we will maintain a visible watermark (the Gemini sparkle) on images generated by free and Google AI Pro tier users, to make images even more easy to detect as Google AI-generated." This is part of broader AI content disclosure regulations like the EU AI Act.

Does the tool work on Google Workspace AI-generated images?

Yes. Any image with the Gemini sparkle watermark - whether generated through the Gemini app, Google AI Studio, Google Workspace features, or any other Google AI product - can be processed by this tool.
