About
Green Screen Remover is a single-purpose web tool: drop in a video or a photo shot against a green or blue screen, and get the subject back with the backdrop removed — as a transparent PNG, a PNG sequence or a transparent WebM.
Who runs this site
This site is run under the name Green Screen Remover. It is an independent, single-page tool site — not a studio, an agency or a media company. What it publishes is the tool itself and the handful of pages that explain it.
What the tool actually does
The whole job happens in your browser tab. When you drop a file in, the page:
- reads the backdrop colour from the border of the frame, so you rarely have to pick it by hand;
- converts every pixel to YCbCr and measures the distance from the key colour in the Cb/Cr plane only — which is why a shadow falling across the screen still keys out;
- switches to a luminance key when the backdrop has almost no colour in it, the one case a chroma key cannot separate a white wall from a white shirt;
- pulls the green light that bounced off the screen back out of hair, skin and light clothing;
- hands you the result as a transparent PNG, a ZIP of PNG frames, or a transparent WebM recorded from the keyed canvas.
Why it is free
There is no server doing the work, so there is no per-file cost to recover and nothing to charge per export. The site is supported by advertising instead. That is the entire business model: your file never leaves your machine, and the page pays for itself with ads.
What it deliberately does not do
- It does not upload your file. There is no server-side processing and no render queue.
- It does not ask for an account, an email address or a payment.
- It does not stamp a watermark on the result.
- It does not pretend to have a manual brush or a rotoscope tool. Colour is the only lever this key has, and the page says so rather than showing you a button that does nothing.
- It does not keep your file. Close the tab and it is gone.
How it is built
One HTML file, one stylesheet, one script. No framework, no build step, no CDN and no web fonts. The tool works offline once the page has loaded, which is the honest test of whether the processing really is local.
