GeminiErase is a free Gemini watermark remover that works entirely in your browser. No upload. No AI guessing. Whether you need to remove the Nano Banana logo or the Gemini 4-pointed star overlay, our reverse alpha blending algorithm restores your original pixels in under 2ms.

THE TOOL

Clean Your Image mathematically.

The Math Behind the Magic

01

We Detect It

We detect the visible watermark region quickly and accurately, then prepare it for clean pixel restoration.

What is GeminiErase?

GeminiErase is a free, browser-based tool that removes the visible watermark from images generated by Google Gemini. It uses a reverse alpha blending algorithm to mathematically reconstruct the original pixels under the watermark, requiring no server upload, no account, and no AI model inference. Processing completes in under 2 milliseconds.

Common Questions

Yes, this works on Gemini images that contain the visible watermark. Upload the original image file (not a screenshot or resized copy) for best results.
No. All processing happens entirely in your browser using JavaScript. Your image never leaves your device, and we have no server-side processing or storage. This ensures complete privacy and security.
The visible watermark is the 4-pointed star logo you can see. SynthID is an invisible, imperceptible watermark embedded at the pixel level. This tool only removes the visible watermark. SynthID remains untouched.
Yes. GeminiErase is free forever for everyone.
The watermark uses partial transparency (alpha blending). On very light or very dark backgrounds, the contrast of the restored pixels might differ slightly from surrounding areas. The pixels are mathematically correct, but human perception varies.
The watermark removal process itself is free and unrestricted. However, you must comply with Google's Gemini terms of service regarding image usage. Always check the license of AI-generated content before commercial use.
AI inpainting guesses what pixels should be there. We use mathematics to calculate the exact original values. Our method is deterministic, accurate to 99.9%, and completes in under 2ms. No model inference required.
The 4-pointed star watermark is a visible logo Google adds to every image generated by Gemini. It appears in the bottom-right corner of the image and is separate from SynthID, which is Google's invisible watermark. GeminiErase removes this visible mark mathematically.
Yes. The Nano Banana watermark is the same visible Gemini star logo applied to images generated by Nano Banana (Gemini Flash Image). GeminiErase detects and removes it using the same reverse alpha blending process.
Removing the visible watermark is generally permitted for personal use. You must still comply with Google's Gemini terms of service regarding how you use the generated images. GeminiErase processes everything locally in your browser and does not store or transmit your images.
The Gemini watermark is composited onto images using alpha blending, a known mathematical formula. Because we know the formula and the watermark's alpha values, we can solve the equation in reverse and calculate the exact original pixel values underneath. This is why results are pixel-accurate, not AI-guessed.
