Gemini Logo Remover — Remove Gemini & Veo 3 Watermarks

Drop in an image from Gemini, Nano Banana, or Veo 3, and this Gemini logo remover erases the small sparkle watermark and gives you a clean, lossless copy back — processed entirely on your device. No uploads, no accounts, no waiting on a server.

This exact before/after pair was produced by the engine running in this site — no retouching.

How it works

Three steps, entirely in your browser.

1

Upload an image

Choose or drag in a Gemini-generated JPG, PNG, or WebP image.

2

Auto-detect and remove

The engine matches known Gemini output sizes, locates the watermark, and reverses the alpha blend that produced it.

3

Download the clean image

Compare before/after with the slider, then copy or download the restored file.

Built for Gemini's visible watermark

A mathematical approach, not a guess.

Lossless restoration

Uses reverse alpha blending to solve for the original pixel values instead of AI inpainting — the result is exact, not guessed.

Runs entirely on-device

Nothing leaves your browser. There is no upload step and no server processing your images.

Automatic detection

Matches your image against known Gemini output dimensions to predict watermark size and position automatically.

Batch support

Select multiple images at once and process them together with the same one-click workflow.

Video support

Gemini and Veo 3 video watermarks are supported too — see the video tool.

Open pipeline

The detection and restoration engine is open source, based on the original Reverse Alpha Blending research.

FAQ

Common questions about removing Gemini watermarks.

Is this a Gemini logo remover?

Yes. Whether you're looking for a Gemini watermark remover, a Gemini logo remover, or just a Gemini remover, this is that tool: it targets the small sparkle logo Gemini adds to generated images and removes it losslessly and for free, right in your browser.

Does this upload my images anywhere?

No. Every step — decoding, detection, and restoration — runs locally in your browser tab.

Will this work on any watermarked image?

It targets Gemini's visible bottom-right watermark on known output sizes. Unsupported sizes or watermark styles may be skipped rather than guessed at.

Does it remove SynthID or other invisible watermarks?

No — this only removes the visible logo overlay. Invisible/steganographic watermarking is a separate mechanism this tool does not touch.

Is it really free?

Yes. The processing engine is open source and runs on your device, so there's no per-image cost.

Does this work on Nano Banana images?

Yes. Nano Banana is the nickname for Google's Gemini image generation feature, and it stamps the same sparkle watermark as other Gemini outputs — this tool detects and removes it the same way.

Can I remove watermarks from multiple images at once?

Yes. Select or drag in multiple images and they're processed as a batch, each with its own before/after preview and download.

Will it work on watermarks from other AI tools, not just Gemini?

This tool is purpose-built for Gemini's specific watermark pattern and calibrated alpha maps, so it won't reliably remove watermarks from unrelated AI image generators.
