Gemi Eraser
한국어
Pick an image. That's it.
Gemi Eraser finds the watermark and removes it on its own. There's nothing to set up. You can check the result side by side with the original.
Take the sparkle off
your Gemini images
Gemi Eraser is an Android app that removes the visible watermark — the sparkle logo in the bottom-right corner — from images made with Google Gemini, entirely on your phone, without uploading them. It's free with ads and has no daily limit; a one-time lifetime purchase removes the ads and unlocks batch processing.
Get it on Google Play
What Gemi Eraser does
Pick an image and Gemi Eraser finds the logo in the corner and removes it. It all happens on your phone. Nothing gets uploaded.
Processed on your phone
Detection and removal both happen on your device, and your images are never uploaded. That also means it works without an internet connection.
Share straight in, or clean a batch
Share an image from another app to Gemi Eraser and it gets cleaned right away. Picking several images and cleaning them in one go is a Premium feature.
Restored, not painted over
Because the logo's shape and transparency are known, Gemi Eraser reverses the blend to recover the original pixels underneath. Only the watermark area changes. Results are saved as lossless PNG, and your original file stays untouched.
Compare results, or fine-tune by hand
Not quite clean? Tap View other results to zoom in and compare candidates, then use Adjust to set the position, size and strength yourself.
History
Cleaned images collect in History, where you can save, share or copy them again later. It keeps 100 by default (or unlimited, if you choose), and you can turn History off if you'd rather not keep anything.

Gemi Eraser is a good fit if you
- want to use a Gemini image in slides, a blog post or on social media, but the sparkle in the corner gets in the way. Just pick the image on your phone.
- don't want to upload your images to someone else's server. Everything is processed on your phone.
- want the original picture back, not a smudge where the logo was. Gemi Eraser reverses the blend instead of painting over it, and saves lossless PNG.
Gemi Eraser isn't for you if you
- need to remove something other than Gemini's sparkle logo. It can't remove other services' logos or watermarks, text or objects in photos, or watermarks on videos.
- only have a screenshot or a cropped or resized copy. If it isn't the original Gemini file, the watermark may not be detected or may not come off completely.
- want to erase every sign that an image was made with AI. Gemi Eraser removes only the visible logo; SynthID, the invisible watermark, stays in the image.

Questions people ask
How do I remove the Gemini (Nano Banana) watermark on my Android phone?
Use Gemi Eraser. It removes the semi-transparent sparkle logo in the bottom-right corner of images made with Gemini, right on your phone. Pick an image and it finds and removes the watermark on its own; there's nothing to set up. It runs on Android 10 and later.
Is there a free Gemini watermark remover with no daily limit?
Gemi Eraser is free and has no daily limit. In return, an ad plays before the result when a watermark is found, and there are ads in the app. The ad before the result only comes the first time each day: watch it to the end and the rest of the day's results show right away, but if you close it early, that result is canceled. Cleaning several images at once is a Premium feature.
How much does it cost to remove the ads? Is it a subscription?
It's a one-time purchase, the Ad-free Lifetime Pass, not a subscription. It's US$1.99 in the US, and prices vary by region. It removes all ads and unlocks batch processing.
Why does it say "No watermark detected"?
Usually because the image isn't an original Gemini file. Gemi Eraser only removes the sparkle logo Gemini adds to its images, so there's nothing to find on other services' logos or on regular photos. Even with a Gemini image, a screenshot, a cropped or resized copy, or a file re-saved by another app may not be detected. Try the original image exactly as you downloaded it from Gemini.
Part of the watermark is still there. What can I do?
On the result screen, tap View other results to zoom in and compare other candidates. If traces remain, use Adjust on that screen to set the position, size and strength by hand. Leftover traces usually mean the image isn't the original file.
Are my images uploaded? Does it work offline?
No. Your images are processed on your phone and never uploaded. That's why image processing works without an internet connection. The app does go online for ads, anonymous usage stats and crash reports, checking for app updates, and verifying purchases through Google Play.
Does it need access to my photos?
No. Gemi Eraser doesn't ask for permission to read your photos or storage. It only gets the images you pick with Android's photo picker or share to it from another app. It doesn't use accessibility access either.
Will my image lose quality? Where are results saved?
Only the pixels in the watermark area change; the rest stays as it was. When you save or share a result, it's stored as a lossless PNG in Pictures/GeminiEraser on your device, and your original file isn't changed. Very large images, over about 18.9 megapixels, are scaled down before processing.
Does it remove SynthID too?
No, SynthID stays in the image. Gemini images carry both the visible logo and SynthID, an invisible watermark; Gemi Eraser removes only the visible logo.
Can I remove watermarks from several images at once?
Yes, with Premium. On the free plan, you clean one image at a time. Select several images and they're cleaned one after another; Android's photo picker sets how many you can select at once. Sharing several images from your gallery or another app also starts a batch.
Is there an iPhone version? Does it work on videos?
No. Gemi Eraser is for Android 10 and later, and there's no iPhone version. It works on images only, so it can't remove watermarks from videos, such as those made with Flow.
What happens to my History when I switch phones?
Images in History are stored only inside the app and are deleted when you uninstall it. Save the ones you want to keep first; saved images are in Pictures/GeminiEraser on your device. There's no account or sign-in.
