Green Screen Studio
Remove green or blue screens, refine edges, and put your footage anywhere. All video processing stays on your device. Export availability depends on your browser.
Your original stored data has been preserved. Download a raw copy before resetting it. Automatic saving is paused until you choose Reset.

Playback & trim
Keyboard: focus the preview, press Space to play/pause, or Left/Right to step by 0.1 seconds.
Trim defines the section exported, not a destructive edit. Exports are limited to 120 seconds per segment for browser reliability.
Export video
MediaRecorder support is advisory: export can fail at runtime if the device has insufficient resources. Exports are processed in real time, and switching tabs cancels the operation. A 200 MB browser memory safeguard stops unusually large recordings.
Video format is selected from your browser's supported recording codecs (typically WebM, sometimes MP4). No lossless alpha video is promised. Export runs in real time, so keep this tab visible. Optional audio requires browser support and should be checked in the finished file.
How green screen editing works
PixelOkay compares every video pixel with your selected key color, adjusts edge transparency and composites the subject over your new background. Unlike AI background removal, this requires a reasonably uniform colored backdrop. Uploads are processed in browser memory and aren't sent to PixelOkay servers.
Does it remove any background automatically?
No. This is a chroma key editor for green, blue, or other approximately uniform colored backgrounds. It does not segment people from complex backgrounds.
Why is my export WebM instead of MP4?
Your browser determines which MediaRecorder codecs are supported. The editor checks support before export and downloads the actual recorded format. MP4 output is not guaranteed.
Can I export a transparent background?
Use Transparent mode and Save PNG to get a transparent still. Browser video recording generally does not provide a portable alpha channel, so choose a solid, gradient or image background before exporting video.
Will my video be saved when I close the browser?
No. Effects/settings may be saved in this browser, but original video and background-image files stay only in your current tab session. Export settings and finished media to keep a backup.
