What is Change Background?
Change Background swaps what's behind a person or product for white, studio blue, a custom colour, a gradient, your own picture, a blur of the original or transparency. Subject masking runs in your browser with U²-Net-P — your photo is not uploaded for AI cutout. Auto starts on a white studio background; refine edges with erase/restore, then download at original resolution.

How it works

- Download PNG, JPG or WebP at the same resolution. For advanced retouch, continue in Photo Studio Pro.
FAQ
Is my photo uploaded?
No — subject masking runs in your browser. Background pictures you pick also stay on this device. Nothing is sent for AI cutout.
Can I make a white or blue background?
Yes — white is the Auto default; studio blue and custom colours replace the real background behind the subject, not just empty canvas corners.
Does it lower the resolution?
No. The result is rendered from your original photo at the same width and height.
Can I get a transparent PNG?
Yes — choose Transparent and download PNG or WebP.
Does blue only fill empty corners?
No — with a real subject mask, studio blue (and other colours) replace the background behind the person or product.
