An honest, in-browser chroma-key tool — upload a green/blue-screen video, click the background with the eyedropper, tune the key, and download. No sign-up, no watermark, and your video never leaves your device. (This is real chroma keying, not AI magic — and we say so.)
or click to browse — MP4, WebM, MOV work best. Everything runs on your device.
WebM export = your keyed video over the chosen background (transparent preview shown as checkerboard). PNG still = one transparent frame, always reliable. Export size reframes to 16:9, 9:16, 1:1 or 4:5 — padding stays transparent (it takes your background color only in the WebM-over-color export). Audio is carried over when the browser provides it.
Three steps. No account, no upload, no waiting room.
Drop a green/blue-screen MP4, WebM or MOV. It loads straight into your browser — nothing is sent anywhere.
Hit the eyedropper and click your background, or pick the green/blue preset. Slide tolerance, edge softness and spill reduction until the preview is clean.
Export a WebM video over your chosen background color, or grab a transparent PNG still of any frame. Free, no watermark.
Built to beat the old "free*" background removers on the things that actually matter.
No 5-second limits, no 360p paywall, no "sign up to continue". If your device can play it, KexCut can key it.
Every frame is processed locally with canvas. There is no server, no account, no upload — your footage never leaves your device.
Sample the exact background color from your own frame, instead of guessing. Uneven lighting? The tolerance slider has you covered.
Green fringes on hair and edges get neutralized with the spill-reduction slider — the detail the toy keyers skip.
No footage handy? One click loads a sample green-screen clip so you can try every control immediately.
This is chroma-keying for green/blue screens — we never pretend it's AI segmentation of arbitrary backgrounds.
The old free tier of unscreen.com gave you 5-second clips at 360p with a watermark — then it moved behind Canva's paywall. Here's the honest comparison.
| KexCut | unscreen.com (now Canva) | unscreen.io | |
|---|---|---|---|
| Price | Free forever | Freemium (5s / 360p free) | Free + paid tiers |
| Sign-up | Never | Required for more than 5s | Not required |
| Watermark | None | Yes, on free | Small, on free |
| Privacy | 100% in-browser | Uploads to their servers | Local processing |
| Method | Chroma key (honest label) | AI (paid) | AI |
| Key controls | Eyedropper + tolerance + spill | Automatic only | Automatic only |
Straight answers, no marketing fog.
Yes — free forever. No account, no watermark, no clip-length or resolution paywall. The only limit is what your own device can process smoothly.
No, and we won't pretend otherwise. KexCut is a chroma-key (green screen) remover: it removes green or blue screen backgrounds you filmed. True AI subject-segmentation of arbitrary backgrounds can't run privately in a browser — any tool claiming "AI" here is uploading your video to a server.
Never. Your file is read by your browser and every frame is keyed locally on a canvas. There is no backend, no analytics on your footage, nothing to leak.
Chroma green and chroma blue presets are built in, and the eyedropper can sample any color from your frame. Even, well-lit backgrounds key the cleanest; the tolerance slider handles uneven lighting and the spill slider kills green fringes.
The Download WebM button exports your keyed video composited over your chosen background color (or over transparency in the experimental alpha build). The PNG still button always gives you one fully transparent frame — perfect for thumbnails. The Export size control reframes the output to 16:9, 9:16, 1:1 or 4:5; any padding around the video stays transparent (in the WebM-over-color export it takes your chosen color).
Your subject probably contains the key color (green shirt on a green screen is a classic). Lower the tolerance, raise edge softness, or re-pick the key color from the darkest corner of the background with the eyedropper.
