Video Trimmer
Trim a video to the section you want by start/end time. Uses stream copy so it's fast and lossless. Runs in your browser.
⚡ Runs entirely in your browser via ffmpeg.wasm. The engine (~30 MB) downloads on first use; large files are slow and limited by your device's memory. Nothing is uploaded.

Frequently asked questions
Does trimming re-encode the video?＋
It cuts to your start and end time without re-encoding where possible, which is fast and preserves the original quality.
Will the cut be frame-accurate?＋
Cuts without re-encoding snap to keyframes, so the start may shift slightly to the nearest keyframe.
Are my videos uploaded?＋
No — trimming happens locally in your browser.
