How it works

Three steps to a clean image

01
Upload or drop your image
Drag and drop, click to browse, load from a URL, or paste from your clipboard. JPEG, PNG, WebP, and AVIF formats all work.
02
Click the remove button
The tool applies reverse alpha-blending using a reference map of the Gemini logo to mathematically reconstruct original pixel values beneath the watermark.
03
Download the clean image
The result is rendered in the right panel. Download your watermark-free image as a lossless PNG in one click. Nothing is sent to any server.
FAQ

Common questions

What exactly is the Gemini watermark?▾
Google's Gemini image generation models embed a small, semi-transparent logo — colloquially known as the "nano banana" — in the bottom-right corner of every image they generate. It is a C2PA-standard watermark identifying the image as AI-generated content.
Is this tool completely free?▾
Yes. No account, no subscription, no hidden payment. It is part of the free tools collection on malikarsalan.com, built by the same team behind ScanQR.org, which serves over 1.8 million users per month.
Does my image get sent to a server?▾
No. All processing runs locally in your browser using the HTML5 Canvas API. Your image never leaves your device. There are no analytics attached to the tool itself and no file storage of any kind.
What image formats are supported?▾
You can load any image format your browser supports — JPEG, PNG, WebP, GIF, or AVIF. The output is always exported as a lossless PNG file to preserve maximum quality after the removal pass.
How does the removal algorithm work?▾
The tool uses reverse alpha-blending. It holds a reference alpha map of the Gemini watermark logo and for each pixel in the watermark region it solves the blending equation backwards: given the watermarked value and the known logo alpha, it calculates what the original background pixel must have been. The result is mathematically recovered — not inpainted or guessed.
Will it work on other types of watermarks?▾
This specific tool is designed exclusively for the Gemini AI watermark (nano banana logo). It uses a hard-coded reference of that particular watermark. For other types of watermarks, a different approach — such as the AI Watermark Remover tool also available on this site — would be needed.
About this tool

Remove Gemini AI watermarks from images online

The Gemini Watermark Remover on malikarsalan.com is a free browser-based tool that strips the semi-transparent Gemini AI logo from images generated by Google's Gemini models — without uploading your files anywhere, without creating an account, and without paying anything.

It is built and maintained by Malik Arsalan, a tech entrepreneur from Muzaffarabad, Azad Kashmir — the same person behind ScanQR.org, which serves over 1.8 million users every month, all through organic search with zero paid advertising.

The removal algorithm is a port of the open-source gemini-watermark-remover project. It uses reverse alpha-blending — rather than smearing surrounding pixels (inpainting), it mathematically recovers original pixel values using a reference copy of the known Gemini logo's transparency map. Results are typically clean with no blotchy artefacts.

The tool handles both small (48×48 px) and large (96×96 px) watermark variants, automatically choosing the correct configuration based on your image dimensions. Images larger than 1024×1024 px use the large logo reference; all others use the small one.
