WatermarkWipe
How to Remove the Gemini Watermark from Your AI Images
A small white star sits in the bottom-right corner of every image Google Gemini generates. Here is exactly what that watermark is, why it is there, and the cleanest way to take it off without losing any image quality.

The fastest way: 10 seconds in your browser
If you just want it gone, the entire process takes about ten seconds and runs entirely on your device. Your images never leave your browser.
- Open the tool. Visit watermarkwipe.com on any phone or computer. Nothing to install, no account required.
- Drop your Gemini image. Drag and drop, click to browse, or paste from your clipboard. You can drop several images at once.
- Download the clean PNG. The tool finds the star, reverses the watermark blend, and gives you back the original pixels. A before/after slider lets you verify the result.
What is the Gemini watermark?
When you generate an image with Google Gemini, including with the image models internally referred to as Nano Banana, a small four-pointed star is composited into the bottom-right corner of the result. It is the same shape Google uses across its AI products, painted in white with partial transparency. The size and exact margin change depending on the output resolution, but the position is always anchored to the bottom-right corner.
This is the visible watermark. There is also a separate, invisible watermark called SynthID that Google embeds across the entire image. The two are different things and only the visible one is in scope here.
Why does Google add a watermark to Gemini images?
The watermark is part of Google's content-provenance push. As AI-generated imagery becomes harder to distinguish from real photos, Google labels its outputs so people can tell where the image came from at a glance. This is a reasonable goal, but for personal projects, mockups, social posts and creative work on your own images, the watermark in the corner is just an artefact that needs to come off.
Using the tool on images you created yourself is fine. Using it to misrepresent AI-generated images as photographs, or to strip attribution you are required to keep, is not. WatermarkWipe also does not touch the invisible SynthID signal, so AI-detection tools that look for it will still flag the image.
Why "AI inpainting" tools give worse results
Most free watermark removers online use generic AI inpainting: they detect a region, throw it away, and ask a model to invent plausible pixels in its place. That works for unknown logos, but it has three big downsides on a Gemini image:
- It hallucinates pixels. The corner of the image becomes a guess, not the truth. Faces, hands, text or fine textures behind the watermark often come back distorted.
- It re-compresses the whole image. Even areas that did not need editing get blurred or smoothed by the model's output.
- It uploads your image. Most of these tools run on a server, which is slower and means a copy of your image now exists on someone else's hardware.
The Gemini watermark is a known shape applied with a known blend, in a known position. That means the math is reversible. Instead of guessing what was under it, the tool peels the blend back off and the original pixels return exactly as Gemini drew them, with no AI inpainting, no guessing and no quality loss.
What sizes are supported?
WatermarkWipe ships with calibration data for every official Gemini output resolution, including:
- 1024 × 1024 (square)
- 1248 × 832, 1408 × 768 (landscape variants)
- 832 × 1248, 768 × 1408 (portrait variants)
- 1184 × 880, 880 × 1184 (newer 4:3 / 3:4 variants)
Resized copies of any of these are detected automatically: the tool scales its internal watermark templates to match. Cropped images are not supported, because once the corner is cut off, the watermark position can no longer be located.
Supported file types: PNG, JPEG and WebP. Output is always a clean PNG so no further compression is added on top.
Common questions
Will the image still be detected as AI-generated?
Probably yes. Google embeds an invisible signal called SynthID across the whole image, not just in the corner. WatermarkWipe does not remove SynthID and does not claim to make any image undetectable.
Does this work on photos that I edited inside Gemini?
Yes, as long as the corner of the image was not cropped after Gemini finished. Whatever Gemini outputs ends up with the same watermark in the same place.
Can I batch-process many images?
Yes. Drop a folder, or select multiple files at once. Each image gets its own result card and you can download everything at the end as a single ZIP.
Is the output really the same as the original?
Yes. Outside of the watermark area, every pixel is untouched. Inside the watermark area, the blend is reversed mathematically. You can verify it yourself with the before/after slider on each result.
Does the tool cost anything?
No. It is free, runs in your browser, has no sign-up, and there are no usage limits.
