Erase anything from a photo
AI watermarks
The ✦ sparkle that Gemini, Nano Banana and other generators stamp on images — found and erased automatically.
Objects & clutter
Power lines, signs, trash cans, a stray hand — brush over anything you wish weren’t in the frame.
People & photobombers
Wipe a stranger out of the background of an otherwise perfect shot.
Text, logos & captions
Stock-photo overlays, captions, brand marks and stamps lift cleanly off the image.
Dates & timestamps
Erase the orange camera date burned into old photos.
Blemishes & spots
Dust, sensor spots and small skin blemishes disappear into the background.

A watermark remover that respects your image
Private by design
Images are processed locally with WebGPU and WebAssembly. They never leave your browser and nothing is stored.
Actually free
No sign-up, no credits, no daily caps. Because everything runs on your device, there are no server bills to pass on.
Studio quality
A MI-GAN inpainting model rebuilds real texture behind whatever you erase, instead of smearing a blur over it.
Questions, answered
- Is Unmark free?
- Yes. Unmark is completely free with no sign-up, no credits and no daily limits. Because everything runs on your own device, there are no server costs to pass on.
- Can Unmark remove objects and people, not just watermarks?
- Yes — Unmark is a full magic eraser. Brush over any object, person, sign, text or blemish and the model reconstructs the background behind it. Detecting and removing the AI watermark is just the one-tap default.
- Are my images uploaded anywhere?
- No. Every image is processed locally in your browser using WebGPU and WebAssembly. Your photos never leave your device and nothing is stored on a server.
- What watermarks can Unmark remove?
- The visible sparkle that Gemini, Nano Banana and other AI generators stamp on images, plus logos, text, captions, timestamps and small unwanted objects.
- Does Unmark remove invisible watermarks like SynthID?
- No. Unmark only removes visible marks. It does not detect or strip invisible provenance watermarks such as SynthID, and it should not be used to misrepresent AI-generated images.
- What image formats and sizes are supported?
- PNG, JPG and WebP up to 4096 pixels on the longest side. Cleaned images are saved as PNG.
- Can I use it on any image?
- Use Unmark only on images you own or have the rights to edit. Removing watermarks or content from other people’s copyrighted work may be illegal.
