Yes, the visible Gemini watermark can be removed, and here it can be done in your own browser without uploading the image anywhere. What cannot be removed is SynthID, the invisible pattern Google embeds in the pixels — our tool does not touch it, and neither should anything claiming to.
The twelve questions below are the ones that come up most often, including several where the honest answer is "it depends on your file".
About the mark itself
1. What exactly am I trying to remove?
A white sparkle logo in the bottom-right corner of the image. It is drawn on with ordinary alpha compositing, which is what makes it reversible. It is not encoded into the file's metadata and it is not part of the picture's content — it is an overlay.
2. Is the watermark and SynthID the same thing?
No, and this is the single most common misunderstanding. The visible watermark is the logo you can see. SynthID is an invisible signal woven into the pixel data itself. Removing one has no effect on the other. Our tool removes the visible mark only, and says so on the page rather than implying otherwise.
3. Can I just avoid the watermark instead of removing it?
Yes, if you have not generated the image yet. Gemini has a Media watermark setting that stops the visible mark being added. The catch is that it only applies to new generations — it cannot clean up images you already have. The official-route write-up covers where the setting lives.
About your file
4. Why do screenshots come out worse than originals?
Because the arithmetic needs the original pixel values. A screenshot is a re-rendering: the image has been scaled, possibly re-compressed, and the colours around the logo may have shifted slightly. The reverse blend is exact only when it is working on the same numbers Gemini wrote. Use the file Gemini gave you, not a screenshot of it, wherever you can.
5. Which formats work?
PNG, JPEG and WebP, one image at a time. You get the cleaned file back as a PNG or a JPEG, written by your browser.
6. Is there a file size limit?
Yes, one: 60 megapixels. That is a pixel count, not a byte count — there is no cap on how large the file is. An image above the limit is refused with a message suggesting you export a smaller copy.
7. Does it work on video?
No. This tool handles still images only, and we would rather say that plainly than let you upload a video and find out. Video watermarks are a genuinely different problem, and they are not what this page solves.
About the output and your privacy
8. Where does my image go when I use this?
Nowhere. The file is read by your own browser, the calculation runs on your own device, and the result is written by your browser. Nothing is uploaded, nothing is stored, and there is no server-side copy to delete. That is a design constraint rather than a marketing line — the privacy page states it and the method page explains how it can work locally.
9. Do I need an account, or is there a daily limit?
Neither. There is no sign-up, no login, no payment and no per-day cap. Run it as many times as you like.
10. Does the tool leave anything behind in the cleaned file?
Only the pixels outside the watermark box, copied unchanged from your original, plus the recomputed pixels inside it. SynthID and C2PA metadata are untouched — we do not strip them, and we do not add anything of our own.
11. What if the result looks wrong?
It usually means the template does not match the image. Gemini has shipped two watermark geometries, and the tool scores both, but a heavily cropped or rescaled picture can defeat that. Try pinning the other template by hand, or nudge the watermark box — it can be dragged directly on the preview. Adjusting the watermark strength is the other lever: lower it if the cleaned area comes out too dark, raise it if a ghost of the logo remains.
12. Is removing the watermark allowed?
Google's published policy does not prohibit taking the visible mark off, and since August 2026 the company has shipped a setting that stops it being added at all. What the rules do care about is misrepresenting where an image came from. That distinction is the whole subject of our write-up on the legality question — and none of this is legal advice.
