LoopSliceLoop, slow-mo & export any video, anywhere.
A Chrome extension that drops pro trim controls onto every HTML5 video — Reddit, X, YouTube, anywhere. No uploads, no account, no servers. Try the real controls right here 👇
Works on Chrome & Chromium browsers • Manifest V3
Everything, on every video
Loop, Boomerang & Reverse
Set an A–B window and repeat it forward, ping-pong, or backward — one mode is always live.
Speed 0.05×–5×
Slow a move down to study it or speed through the boring bits. 1× sits centered on the slider.
Zoom into any region
Draw a box on the video to crop and magnify — the page’s player is never touched.
One-click export
Record a single loop cycle to MP4 (WebM fallback). No uploads, no watermark.
PiP & fullscreen aware
Float the loop in a corner, or keep the controls above fullscreen video.
Optional private mode
Passphrase-encrypt your exports on-device. Off by default — you never have to use it.
Runs entirely on your machine
LoopSlice has no backend and collects nothing. Your videos, your loops, and your exports never leave your browser. Private mode is optional and off by default.
