AI Object Remover

Paint over an unwanted object, person, or text in your photo and let AI fill in what's behind it naturally. Free, runs entirely in your browser.

Whether you're removing a stranger from a vacation photo, cleaning up a distracting sign or watermark, or erasing a timestamp from an old scan, the AI model downloads once to your browser and then reconstructs the painted-over area locally — your photo is never sent anywhere to be processed.

How it works

  1. Upload your photo. JPG, PNG, or WEBP — drag & drop or click.
  2. Paint over the unwanted object. Cover the person, object, or text you want gone.
  3. AI fills in the background naturally. Download the result in a few seconds.

Frequently Asked Questions

Is it free?
Yes, no account needed.

Does my photo get uploaded anywhere?
No, object removal runs entirely in your browser.

Which formats are supported?
JPG, PNG, and WEBP, up to 15MB.

Do I need to sign up?
No.

Can it remove large objects too?
You can adjust the brush size to cover larger areas, but very large or complex areas may look less natural in the result.

How long does object removal take?
After the AI model finishes downloading (once per session, then cached), removing an object typically takes a few seconds to under a minute, depending on your device.

What happens to my photo after I download the result?
Nothing — since everything runs in your browser, once you close or refresh the tab both your original photo and the result are gone from memory; nothing is stored on our end.

Which browsers and devices does it work on?
Any recent version of Chrome, Firefox, Safari, or Edge, on desktop or mobile — no extra software needed, though a device with WebGPU support processes images noticeably faster than one relying on the WebAssembly fallback.
