How it works
UnmarkAI reads the pixels directly above the watermark strip, flips and blends that texture over the mark, then feathers the edges so the repair disappears into the background. Skies, studio backdrops and gradients — where corner stamps almost always sit — come out seamless.
Prefer to trim instead? Crop edge off cuts the marked strip away entirely, which is handy when the mark overlaps detail or you were cropping for composition anyway.
Private by design
Every step runs locally in this page. There is no upload step to trust, no queue to wait in, no copy of your image on someone else’s server. Batch a whole folder — the tool processes each image the moment it loads and hands you a Download all button.
Use it responsibly
The mark on an AI image identifies how it was made. Clean marks from your own generations freely; do not strip marks from other people’s work to misrepresent it. Platforms grant usage rights to your outputs — removing the stamp from your own file does not change what you may do with it.
More ways to clean your images
Is UnmarkAI free?
Completely — every mode, batch included. No account, no watermark of our own, no limits.
Are my images uploaded?
No. All processing runs inside your browser tab. You could disconnect from the internet after loading the page and it would still work.
Which marks can it remove?
Corner stamps from AI image generators — the Gemini family bottom-right mark, and any similar corner placement via the position and size controls.
Will the fix be visible?
On skies, gradients and blurred backgrounds the blend is invisible. On busy detail use Crop mode instead.
Can I process screenshots or scans?
Yes — any PNG, JPG or WebP with a corner mark works. The position controls cover all four corners at three sizes.
How fast is batch mode?
Each image processes the moment it loads — a folder of thirty typically finishes before you have switched back to the tab.
