✂️ Video Trimmer

Trim a video to the exact part you need. Fast mode copies the streams and cuts near keyframes; accurate mode re-encodes so the cut lands exactly where you set it.

Runs entirely in your browser with FFmpeg.wasm. No upload, no account, no video stored anywhere, and no watermark added by this site.

Supported formats and limitations

Your video never leaves your device. Processing runs in your browser with FFmpeg.wasm; there is no upload, no account and no server copy.
The video engine (about 32 MB) is downloaded only after you choose a file and press Process — never automatically when the page loads.
There is no artificial usage limit and no account. Real speed and maximum size depend on your device and browser: large or long videos are slower and may run out of browser memory. A warning is shown for very large files, but no file is hard-blocked for size alone.
Fast mode is a stream copy, so the cut point may snap to the nearest keyframe, usually within a second or two of your chosen time.
Accurate mode re-encodes and is slower, but the cut is exact.
No artificial usage limit: capacity depends on your device and browser. Large or long videos are slower and may run out of browser memory.

Frequently asked questions

Why is my fast trim slightly off?

Stream-copy trimming can only cut at keyframes. Switch to accurate mode when the exact frame matters.

Does trimming change the rest of the video?

No. Only the selected range is kept; everything outside it is removed from the output file.
