Trim Video lets you cut a clip down to a single start and end point — perfect for grabbing the best few seconds of a longer recording or removing dead air at the top and tail. Everything happens in your browser using FFmpeg.wasm, so your footage never gets uploaded and the trim is ready to download in seconds.
Drag an MP4, MOV, WEBM, MKV or AVI file onto the page, or click to browse. It loads straight into the editor — no upload.
Drag the two handles on the timeline, or type exact start and end timecodes, to keep only the part you want.
Choose a format, add optional fades, and export. Your trimmed clip downloads instantly to your device.
Only minimally. Where the cut points allow, we keep the original stream; otherwise the clip is re-encoded once at high quality.
MP4, MOV, WEBM, MKV and AVI are all supported as input, with MP4, MOV or WEBM available as output.
The free tier handles files up to around 250MB, which covers most clips. Larger files are supported on Premium.
No. This tool runs entirely in your browser — your file is processed on your own device and never leaves it. The only network request is an anonymous usage counter.
