About

Drop a video file, mark start and end times, and download the trimmed clip. Uses ffmpeg compiled to WebAssembly, so the whole thing runs locally — no upload, no waiting in a queue. First load is heavy (~30 MB) because the encoder has to come down once.

How to use

Drop a video file (MP4, MOV, WebM, etc.).
Pick start and end times.
Download the trimmed video.

FAQ

Why does the page download a chunk on first load?+

It's pulling ffmpeg.wasm — the video engine that runs in your browser. After the first load it's cached, so subsequent visits are fast.

What file size can I handle?+

Up to roughly 1 GB on a typical laptop. Browser memory is the limit. For huge files, use desktop ffmpeg.
