Green screen remover
Drop a photo or a short clip shot on green or blue, tune the key, and export a transparent PNG or a WebM with alpha. It all runs on your device.
Free, no sign-up. Runs in your browser.
A sample frame. Add your own below, then click the screen to pick its exact color.
How it works
Three steps
01
Add a photo or clip
PNG, JPG, MP4 or WebM. Video is best kept under a minute.
02
Tune the key
Click the screen to sample its color, then set strength, edge softness and spill so hair and edges stay clean.
03
Export
Images save as transparent PNG. Video records to WebM with alpha in Chrome and Edge, or onto a solid color anywhere.

FAQ
Questions
Still stuck? The guides cover installing, agents and licensing in more detail.
Read the guidesIs my video uploaded?
No. Each frame is keyed on a canvas in your browser, so the file never leaves your device and there is no size limit beyond your machine.
Which browsers export video with transparency?
Chrome and Edge record WebM (VP9) with an alpha channel. Safari and Firefox record without alpha, so pick a solid background color there.
How do I get rid of the green fringe on edges?
Raise Spill to pull green out of the edge pixels, then a touch of Softness. Even, bright lighting on the screen helps more than any setting.
Can I put the cut-out on a website?
Yes. A transparent WebM plays on a page like any video. The Cutout Float Hero skill builds a landing hero around a cut-out subject, ready for your agent to install.
