Green Screen Tool
Choose a local video and tune the key color and tolerance to preview transparent background removal in your browser.
A QUICK WALKTHROUGH
How to use this tool
- Choose a video within the stated limits.
- Select green or blue and adjust tolerance.
- Play the video to inspect the local chroma-key preview.
Local chroma key preview
The browser draws decoded video frames to a canvas and makes pixels near the selected green or blue key color transparent. It is a preview, not a promise of a finished edited video.
Limits and privacy
The selected video stays in this browser. Files are limited to 100 MB and 1280×720 preview dimensions; no upload, account, or remote processing is used.
Keying limitations
Lighting, shadows, spill, motion blur, hair, and colors close to the key color can produce artifacts. Tune tolerance and inspect the whole clip.
GOOD TO KNOW
Common questions
Does it export a transparent video?
This version provides a live canvas preview only. A finished video export requires a separately defined codec, container, and audio contract.
Is the video uploaded?
No. Decoding and preview happen locally in this browser.
Can it remove any background?
No. It keys pixels near one selected green or blue color and may leave artifacts.
