Change an image's background for another photo

Replace a photo's background with another image using AI, directly in your browser.

Processed on your device via WebAssembly. Nothing is sent to any server.

or click to select it

Replace a photo's background with another image: the AI cuts out the subject and composites it onto the background you choose, directly in your browser.

Computes the subject's transparency mask with a segmentation model (U²-Net) via WebAssembly, then composites both images on a canvas: the new background is scaled "cover"-style and the cut-out subject is drawn on top.

Use cases

  • Giving a studio background to a photo taken at home.
  • Changing the setting of a product photo.
  • Compositing a montage onto a themed background (landscape, texture, brand color).

How it works

  1. 1

    Upload the main photo

    The one with the subject you want to keep. Click "Remove background": the first time it downloads a model (~19 MB).

  2. 2

    Upload the background image

    It's automatically scaled to cover the whole frame, cropping the excess centered.

  3. 3

    Download the result

    Get the final photo with the new background, in PNG.

Frequently asked questions

What if the new background has a different aspect ratio?

It's scaled to cover the whole frame and the excess is cropped centered, like CSS's "object-fit: cover" — it's never distorted and never leaves empty strips.

Can I try several backgrounds without redoing the cutout?

Each new background recomposes the image, reusing the same already-decoded subject; to start over with a different subject photo, upload it again.
