How Video Trimmer works
Trim in three steps
Upload a video (MP4, MOV, MKV, WebM, AVI, or any format from the list below). Drag the handles on the timeline to set in and out points. Click Trim — processing runs in your browser via WebAssembly, no upload to servers. Download the cut clip; the original file stays on your device.
Why use this trimmer
Frame-accurate cutting without installing software. Supports H.264, H.265, VP9, AV1 and common containers. No file size limits beyond your device; no watermarks or sign-up. Same quality on output as input — we only cut, we don't re-encode the whole file.
Supported Video Formats
MP4, WebM, MOV, MKV, AVI, FLV, M4V, MPG, MPEG, TS, M2TS, VOB, OGV, ASF, WMV, MTS, M2T, GIF
