Trim a Video Online
Cut off the beginning, the ending, or both. Drag the handles to pick exactly what you keep — it all happens in your browser.
Drop a video or audio file
MP4, MOV, WEBM, MKV, AVI, MP3, WAV — up to 500.0 MB.
Trimming happens in your browser. The file is never uploaded.
Trim the Start or the End, Exactly Where You Want
Drop a video in and it plays immediately. Drag the left handle to cut off an intro, drag the right handle to cut off an ending, or move both to pull one section out of the middle. Set a point from the playhead while you watch, or type the timecode if you already know it.
Start, End, or Both
Move one handle to trim just the beginning or just the ending. Move both to keep a section from the middle.
Instant and Lossless
Trimming an ending copies the original stream with nothing re-encoded, so it finishes in moments at the original quality.
Stays on Your Device
The trim runs in your browser with WebAssembly. The video is never uploaded.

Frequently Asked Questions
How do I cut just the start of a video?
Drag the left handle to where you want the video to begin and leave the right handle at the end. Everything before your start point is removed.
How do I cut just the end?
Drag the right handle back to where you want it to stop. Because the clip still starts at the beginning of the file, this trim is lossless and near-instant — the original video stream is copied straight across without being re-encoded.
Will trimming re-encode my video?
Only when it has to. A cut that starts at the beginning is copied without re-encoding. A cut that starts partway in usually lands between the video's keyframes, which a stream copy cannot begin on, so that range is re-encoded to land on exactly the frame you chose. The tool shows which one it will use before you run it.
Is there a size limit?
The browser tool handles files up to 500MB. Above that, use the /api/trim-video endpoint, which takes the same start and end values.
Can I trim audio as well as video?
Yes — MP3, M4A, WAV, FLAC, OGG and Opus. Audio trims are always lossless, whatever the start time.
