What is a green screen remover / chroma key tool?

A green screen remover (chroma key, chromakey, chrome key, green screen chroma key) makes a solid green or blue background transparent so the subject can sit on any new backdrop. People search for “remove green screen”, “green screen removal”, “chroma key green”, “chroma key background green screen”, “green chroma key color”, “chroma green key”, “image keying”, and even “convert green” when they have a flat key color and need a transparent PNG. This tool keys by color distance with tolerance and soft edges entirely in the browser. For click-to-erase arbitrary colors see /make-image-transparent; for messy non-green photo backgrounds see /remove-background-image.

Tips for cleaner chroma keys

Better green screen removal results.
  • 01

    Light the screen evenly

    Uneven green needs higher tolerance — watch that hair does not disappear.

  • 02

    Avoid green wardrobe

    Switch to blue screen when the subject wears green.

  • 03

    Use softness on fine edges

    Hair and semi-transparent props benefit from a soft falloff.

    Sample your exact paint

    Paste the backdrop hex if it is not pure #00ff00.
