Remove backgrounds.Keep the shadows.
Flat backgrounds vanish completely — shadows, glass and glow stay exactly as they were, so the result drops cleanly onto any new background. The matting runs on real pixel data, right inside your browser.

Shadows, glass and glow survive
Most tools flatten your image into a hard cutout. This one models transparency properly: soft shadows keep their falloff, translucent objects keep their colour, and glowing edges stay clear of dark halos.

Questions people actually ask
Are my images uploaded?
No. The engine runs in a Web Worker on your device. The server only receives the background colour, the image size and a one-time challenge — never pixels.
Which formats are supported?
Input: PNG, JPEG, WebP, AVIF. Output: PNG, PNG-8, WebP, AVIF, JPEG and ICO. PDF merge accepts PDFs and images.
Is it really completely free?
Yes. Unlimited background removals, no signup, and your images never leave your device — everything runs locally in your browser.

A drop shadow is background colour multiplied down, which is why most cutters delete it with the background. Here is the luminance model that keeps it, and where that model stops working.

Green fringing: where it comes from and how to kill it
Anti-aliased edges are a mix of foreground and background colour. Keep them and you get a green halo; delete them and the outline gets thinner. Unmixing is the only way out.
