For Gemini & Nano Banana images
Remove the Gemini watermark from images you created yourself — one at a time or a whole batch, free, unlimited, and entirely in your browser.
Your files never leave your device. No upload. No account. No limits.
Use the original, watermarked file you downloaded from Gemini. Screenshots, crops, resized or re-saved copies may fail: the mark may not be found, or a trace may be left behind. Check the zoomed corner before you download.
What’s different
There’s no server behind this page that could receive a picture. That one fact changes everything else on the list.

| Where your image goes | Uploaded to a server for processing | Stays in your browser |
| How many you can do | Credits, or a daily cap | As many as you like |
| Batch processing | Usually a paid feature | Included, and free |
| How the mark comes off | Often AI inpainting that repaints the area | The blend is reversed exactly |

Check it yourself
Local processing is easy to claim. Here’s how to check this one in about ten seconds.
To be exact: the page itself loads over the network like any website — our code and styles. What you won’t find is a single request carrying your image. How to check the network yourself.
How the Gemini Watermark Remover works
Gemini adds its mark by mixing white into your pixels at a fixed strength. A fixed mix can be undone exactly — no AI needed to imagine what was there.
Gemini places it at a fixed size — 48 or 96 pixels — a set distance from the bottom-right corner.
Each pixel under the mark is solved back to its original value. Everything else is copied through untouched.
Compare the corner up close before you download. You make the call, not a score.

This Gemini watermark remover clears the visible corner mark from images you generated in your own Gemini account. The processing runs on your own device, inside your browser — your images are never uploaded, stored, or seen by us.
We only target the visible corner mark. We make no attempt to detect, alter, or remove SynthID, Google's invisible AI watermark.
There is no account, no free trial that expires, and no daily quota. Most Gemini watermark remover sites meter you because every image they process costs them server time. This one runs on your own hardware, so there is nothing for us to meter and nothing to charge for.
That also means this Gemini watermark remover does not get slower when more people use it. Your device is the only machine doing the work.
Because the repair is arithmetic rather than reconstruction, the surrounding image is never touched, re-rendered, or smoothed. The only pixels that change are the ones the watermark was drawn over.
Results download as PNG on purpose. Re-encoding as JPEG would compress the freshly repaired area a second time and add blocky artefacts exactly where you just cleaned up. Lossless output keeps the repair intact.
One honest caveat: the reversal assumes the watermark pixels are unchanged. A file straight from Gemini satisfies that. A screenshot, a resized copy, or a re-saved JPEG does not, so the result may keep a faint outline.
People call it different things — the Gemini logo, the star, the sparkle, the ✦ in the corner. It is all the same mark, drawn the same way, so this tool works as a Gemini logo remover in exactly the sense people mean: it takes that corner logo off images Gemini generated for you.
What it does not do is remove logos in general. A brand logo you placed in a design, or a logo that is part of the scene Gemini drew, is not an overlay with a known opacity, so there is nothing to reverse. The engine leaves those pixels alone.
This Google Gemini watermark remover is built for one job: images generated in Gemini that still carry the sparkle in the bottom-right corner. That includes pictures made with Nano Banana, Google’s image model inside Gemini, at every output size the app currently produces.
Start from the file Gemini gave you, with the mark still on it. The engine looks for the watermark at the exact size and position Gemini draws it, so a screenshot, a cropped or resized copy, or an image that never had the mark may not process correctly. If a result looks off, go back to the original download and try again.
Switch the tool above to Batch, or simply drop several images at once, and the whole set is cleaned in one pass. Files are processed one at a time, in order, and each reports its own result — a file that fails does not stop the rest.
Strictly one at a time is deliberate. A single 8000×8000 image needs roughly 244 MB just to hold its pixels; several at once is enough for a mid-range phone to kill the browser tab without warning. Each image releases its memory as soon as it is done, so the size of the batch is not what limits you.
PNG, JPEG, and WebP, from 80×80 up to 8000×8000 pixels, and up to 30 MB per file. There is no file count limit and no daily quota.
Works in Chrome and Edge 90+, Firefox 105+, and Safari 16.4+, on desktop and mobile. Older browsers are told so directly rather than failing silently.
The engine recognises one specific watermark pattern: the visible corner mark Google Gemini adds to generated images. It cannot process anything else, and it is not built to.
Free and unmetered only means something next to what the alternatives ask for. This is what each tool states on its own public pricing page — where a page does not say whether batch processing is gated, we do not guess.
| Tool | Free tier | Batch | Account |
|---|---|---|---|
| This tool | Unlimited, no credits | No cap on file count; ZIP splits every 50 files or 200 MB | Not required |
| dewatermark.ai | 3 credits per day, 1 credit per image | Up to 50 images at once, listed as a paid-plan feature | Required |
| PixelBin | 10 credits on sign-up, then from $15/month for 250 credits | Up to 50 images at once | Required |
Checked 10 September 2026 against each vendor’s public pricing page. Prices and limits change, so verify before relying on them. PixelBin’s pricing page does not state whether batch editing is restricted to paid plans, so we make no claim either way.
Common questions

This tool is designed for processing images you created yourself in your own Gemini account, or content you are authorized to modify. We do not support or enable removing watermarks from content that belongs to someone else.
No. Your images are processed on your own device, inside your browser. The image data is never sent to us — there is no upload step, and no server on our side that could receive it. To be precise: the page itself does load over the network, like any website — our code, styles, fonts and the sample images. So you will see some network activity in Developer Tools. What you will not see is any request carrying your image. The clearest way to check: once the page has finished loading, turn off your Wi-Fi and process an image. It still works, because nothing needed to leave your device in the first place.
No. Our engine is built to detect one specific watermark pattern used by Google Gemini. It does not work on stock library watermarks — technically, not just as a matter of policy. Removing watermarks from licensed or third-party content may violate copyright law, and we do not support it.
No. SynthID is Google's invisible AI watermark, embedded during image generation. This Gemini watermark remover only targets the visible corner mark — it makes no attempt to detect, alter, or remove SynthID, and we do not offer that as a feature. One thing worth knowing: saving a cleaned image writes a new PNG file, so metadata attached to your original file — including C2PA Content Credentials, if it had any — is not carried over. That is a side effect of re-encoding the image, and it applies to almost any image editor.
PNG, JPEG, and WebP. Images must be at least 80×80 and at most 8000×8000 pixels. There is no file count limit and no daily quota — because processing runs on your own device, it costs us nothing.
No. Unlimited, free, no account required. Other tools cap you because every image costs them server time. Ours runs on your device, so there is nothing to meter.
Yes. Switch to Batch, or drop several images onto the tool, and they are processed one after another in your browser. There is no cap on file count; the practical limit is your device, since a long queue of very large images simply takes longer on a phone than on a laptop.
Only that image is affected. It is listed with the specific reason — no watermark found, too large, unsupported format — and the queue carries on. Keep the tab open until the batch finishes: all the work happens in this page, so closing it ends the queue. Your original files are never modified either way.
