Tip: click anywhere on the preview to sample that color as the key color.

A green screen background remover strips the solid backdrop out of your shot and leaves a transparent cut-out. From there you can drop your subject onto a new background — a virtual set, a photo, a solid color, anything. (In video terms this is chroma key: green or blue is the "key" color being pulled out.)

How it works

  1. Open your image or video above.
  2. The tool measures how close each pixel is to the key color. Pixels that match become transparent; everything else stays.
  3. Fine-tune with Similarity threshold, Edge shrink, and Edge smoothing, then export a transparent PNG or WebM.

Background remover vs background editor

"Remover" gives you the transparent cut-out. An editor is the next step: you place that cut-out onto a new backdrop. This tool does the removing; you can composite the result in any editor (or just leave it transparent for overlays and thumbnails).

Diagram: image exports as transparent PNG, video as transparent WebM or PNG sequence, both on-device
Image becomes a transparent PNG; video becomes a transparent WebM or PNG-sequence zip — neither is uploaded.

What to do with the transparent result

Green halo left? raise Edge shrink. Fine hair chewed away? lower shrink and raise Edge smoothing.
