Free Video Trimmer

Cut a video down to the part you want, right in your browser. Scrub to find your moment, set start and end, trim.

What this does: cuts your video to a start and end time, entirely in your browser using a WebAssembly build of FFmpeg. It is free, with no signup and no server upload: the file never leaves your device. The first run downloads a ~31MB engine (cached afterward, instant on later visits); because it runs single-threaded in the tab, it is slower than a desktop app, especially on large files or mobile.

Frequently asked questions

Is this video trimmer free, and is my video uploaded anywhere?

Yes, it is 100% free with no signup, and no, your video is never uploaded. Trimming runs entirely inside your browser tab using a WebAssembly build of FFmpeg, so the file never leaves your device.

Why does the first trim take longer to start?

The first time you use this tool, your browser downloads a ~31MB WebAssembly video engine (FFmpeg compiled to run in the browser). It is cached afterward, so later visits and later trims start instantly.

Does trimming re-encode the whole video, and is that slow?

This tool first tries a fast, lossless cut that copies the video without re-encoding. If that is not possible for your file, it automatically falls back to re-encoding the trimmed section. Either way, processing runs single-threaded in the browser tab, so it is slower than a native desktop app, especially on large files or mobile devices.
