What is chromakeyremover.com?
chromakeyremover.com is a free online tool that removes green (or any solid color) backgrounds from images. It runs entirely in your browser — no image is ever uploaded to a server, no account is needed, and there is no usage limit. You drop in an image, adjust the threshold and edge settings, and download a transparent PNG.
Why was it built?
Most online green screen removers either require an account, impose daily limits, add watermarks, or upload your images to a server where you lose control of them. This tool was built to be the opposite of that: completely free, completely private, and completely unlimited. If you need to remove a green screen from an image, you should be able to do it in seconds without signing up for anything.
How does it work?
The tool uses the browser's Canvas API to read pixel data from your image. It converts each pixel from RGB to YCbCr color space, then compares the chrominance (Cb/Cr) values against the key color you selected. Pixels that fall within the threshold range are made transparent. Edge feathering smooths the transition, and spill removal reduces green color bleeding on the subject's edges. All of this happens on your device — the code is open and inspectable in your browser's developer tools.
Who runs it?
