Getting the remover ready
Reading your file
No Gemini watermark found
This file doesn't carry the visible Gemini sparkle in a place we recognise, so nothing was changed.
- Use the original download, not a screenshot or a copy sent through a chat app.
- Cropped, resized or already cleaned files may no longer show the mark.
That didn't work
How it gets the picture back
The Gemini sparkle is a semi-transparent white shape laid over your picture. Because we have measured exactly how see-through it is at every pixel, CleanClip can reverse it and recover what was underneath, instead of smudging over it.
- Find it. The sparkle is located in each image or video frame.
- Reverse it. The overlay is subtracted pixel by pixel, in the same colour space the file was made in.
- Check it. Drag the slider and zoom in. Save when you are happy.
How do I remove a Gemini watermark from an image?
- Choose, drop or paste the original image from Gemini.
- CleanClip finds the star and removes it, usually in well under a second.
- Drag the slider and zoom into the corner to check it.
- Tap Save image, or Download on a computer. JPG stays JPG; PNG and WebP save as PNG.
Does this work for Nano Banana images?
Yes. CleanClip is calibrated on Nano Banana images in portrait and landscape. It also handles images edited from an already marked image, where the star is stacked several times; those corners are rebuilt from the surrounding texture, so check them closely. Images whose star sits somewhere unusual may not be recognised.
Can I remove the star without cropping?
Yes. The image keeps its exact size and only the corner with the star changes. There is no crop and no blur over the image.
Which image formats and sizes work?
JPG, PNG and WebP, up to 40 megapixels. JPG results are saved as high-quality JPG, PNG and WebP as PNG. Animated images, HEIC, SVG and GIF are not supported. Image metadata is not carried over.
Is the image uploaded or stored?
No. The remover runs inside your browser, so CleanClip never receives your image. Closing the page clears the result, so save it first.
Why is an outline still visible?
A screenshot, a resized copy or a file sent through a chat app no longer matches the original star exactly, so a faint outline can remain. Start with the original download and do not clean the same file twice.
How do I save the image on my phone?
On a phone, Save image opens the share sheet, where you can choose Save Image or your gallery app. On a computer the image downloads.
Need to clean a video instead?
Just drop it in the same box. Videos keep their original sound and save as MP4. There is also a page for the Gemini video watermark remover.
