Keep the subject. Dream up the scene.

The main subject is detected automatically and kept untouched; describe a new setting and a diffusion model paints it behind them, matching the light at the edges.

How it works

An on-device segmentation model (ISNet) finds the person, pet or product. Everything else becomes the area to regenerate, and SD-Turbo — running on your graphics card with WebGPU — paints the new scene from your prompt. The subject's pixels are never altered, and the new background is placed on its own layer.

Great uses

  • Product photos: marble counters, linen, studio sweeps, outdoor lifestyle scenes.
  • Profile pictures: a clean studio backdrop or a soft outdoor blur.
  • Social posts and thumbnails: travel, seasonal or themed backdrops.

Prompts work best when they describe the place and light: “a sunny beach with palm trees, shallow depth of field”.

When to use something else

For a plain white or transparent background, use Change Background — it's instant and doesn't need a graphics card. For a real photo of your own as the backdrop, Change Background's Image option keeps it exact.

FAQ

AI Background Generator questions

Is the AI background generator free?

Yes. It runs on your device with no credits, sign-up or watermark.

Does it change my product or person?

No. The detected subject's pixels are kept exactly; only the background is generated.

Are photos uploaded?

No. Both the subject detection and the generation run in your browser.

Why is the background a bit soft?

Scenes are generated at about 512 pixels and fitted to your photo, which often reads like a natural shallow depth of field. Tick the AI upscaler for more detail.

What do I need?

A recent Chrome or Edge with WebGPU; the first use downloads about 2.6 GB.
