Green Screen Software — free, in your browser

Green screen software turns a solid-color backdrop into a transparent cut-out or a swapped background. The right tool depends on your workflow: heavy video edits want a desktop suite, while a quick one-off cut-out is better done in a browser with no install.

Types of green screen software

Desktop video editors. Premiere Pro, DaVinci Resolve, and Final Cut Pro ship chroma-key effects (Ultra Key, Delta Keyer, Keyer) built for multi-track timelines — the deep option for full productions.
Photo editors. Photoshop keys a solid backdrop via Color Range, which is great for stills.
Online & browser tools. No install, runs on any device, and ideal for a single cut-out — like the tool on this page.
Mobile apps. Phone apps offer clip-on backdrops and keying filters you can use on the go.

What to look for in green screen software

Real chroma key — a true color key, not just a fuzzy background blur.
Transparent export — PNG for images, WebM or a PNG-sequence for video.
No watermark on the free tier.
Privacy — client-side processing means your files never leave the device.
Price — free options exist for light use, so you don't pay for a one-off task.

For a quick cut-out, skip the download: drop your file above, keep the green preset, adjust Similarity threshold, and export a transparent result. Images become a transparent PNG; video becomes a transparent WebM or PNG-sequence zip. Everything runs on your device.

Diagram: image exports as transparent PNG, video as transparent WebM or PNG sequence, both on-device — Image becomes a transparent PNG; video becomes a transparent WebM or PNG-sequence zip — neither is uploaded.

Image or video?

Still image? You get a transparent PNG. Video? You get a transparent WebM or a PNG-sequence zip. Both are processed on your device — nothing is uploaded.

Tips for a clean edge

If a green halo remains, nudge Edge shrink up by 1–2 px.
If hair or fine detail gets chewed away, lower Edge shrink and raise Edge smoothing.
You can click the preview to sample any color as the key — handy for uneven or lit backdrops.

Diagram: green halo fix is raise edge shrink; chewed hair fix is lower shrink and raise smoothing — Green halo left? raise Edge shrink. Fine hair chewed away? lower shrink and raise Edge smoothing.

Common questions

What is the best free green screen software?

For quick, private cut-outs, a client-side browser tool (like this one) is hard to beat: no install, no watermark, no upload. For full video production with timelines and effects, a desktop suite is the deeper option.

Is there a green screen app?

Yes — mobile apps and browser tools both qualify. A browser tool is the flexible pick because one link works on phone, tablet, or desktop.

Are my files uploaded?

No. Everything runs in your browser; we never receive your media.
