Video Trimmer

Cut your video down to the exact moment

The Video Trimmer lets you keep only the section of a video you want and discard the rest. It is ideal for clipping a highlight out of a longer recording, removing dead air at the start or end, cutting a sample to share, or grabbing a single scene without opening heavy editing software. You set a start and end time, and the tool produces a new, shorter video containing just that range.

Everything is processed locally in your browser using FFmpeg compiled to WebAssembly, so your video is never uploaded to any server and stays completely private. To keep trimming fast and lossless, the tool copies the existing audio and video streams directly rather than re-encoding them, which means the cut is quick and the picture quality of the kept section is identical to the original.

How to trim a video

Drag a video onto the upload area or click to browse and select one (MP4, WebM, MOV, and AVI are supported). The video loads into an in-page player, and once its metadata is read the tool fills in the total duration and sets the end time to the full length. Scrub through the preview to find your in and out points.

Enter the Start Time and End Time in seconds; the tool shows the resulting trim length so you can confirm the selection. Click Trim Video and watch the progress bar. When it finishes you can preview the trimmed clip directly in the page and download it as an MP4. If you change your mind, use the Remove link to load a different video.

Tips and things to know

Because the trimmer copies streams without re-encoding, it is extremely fast even on long videos, but cuts can only land on keyframe boundaries. If a trim fails or the start point feels slightly off, nudge the start and end times by a fraction of a second and try again. The output is always saved as an MP4, which plays on virtually any device. Since processing happens in your browser's memory, very large files may be slower to load and trim on low-memory devices.
