What is the Video Trimmer?

A video trimmer online lets you cut unwanted parts off the beginning or end of a clip without installing any software. You load your own video file, pick the exact start and end points on a preview player, and download just the segment you want — perfect for removing awkward silences before you start talking, cutting off the moment you reach for the camera, or snipping the highlight out of a longer recording.

Everything happens locally in your browser. Your footage is never uploaded to a server, so a multi-gigabyte recording trims just as fast as your connection-free computer allows, and nobody else ever sees your private video. The tool plays your clip back for you, shows the total duration, and offers a preview button that plays only your selected segment so you can confirm the cut is exactly right before downloading.

This trimmer works by re-encoding your chosen segment, which keeps the tool compatible with MP4, WebM and MOV files in any modern browser. The honest trade-off is that the download is a silent WebM file — video only, re-encoded at your clip’s resolution — rather than your original container. For best results, keep your trims short: the tool is designed for quick clips (under a few minutes), where the re-encode is fast and the quality stays high.

How to use the Video Trimmer

  1. Drop your video file onto the upload box (or click to browse). MP4, WebM and MOV files are supported.
  2. Watch your clip in the preview player. Note the total duration shown underneath.
  3. Enter the start and end times in seconds — or pause the video at the exact moment you want and press ‘Use current time’ to fill each box precisely.
  4. Press ‘Preview segment’ to play just your selection and check the cut feels right.
  5. Press ‘Trim & download’ to re-encode that segment and download it as a WebM file.

Video Trimmer use cases

Cutting dead air from recordings

Most home recordings start a few seconds early and end late. Trim the silence off both ends and the clip is instantly tighter and more watchable — the single easiest edit you can make to any video.

Snipping highlights for social media

Record a long gaming session or event, then pull out just the 15-second moment worth sharing. Trimming the segment first means you upload a small, fast file instead of a giant raw recording.

Preparing clips for presentations

Trim a demo or testimonial down to the seconds that matter before dropping it into slides. A tight clip keeps your audience’s attention instead of making them watch you fumble with the camera.

Trimming footage before sending

Sharing a video with friends or family? Cut the boring parts first so the file is smaller and the message is clearer. The trimmed WebM plays in any modern browser or media player.

Tips

  • Use the ‘Use current time’ buttons rather than guessing seconds — pause at the exact frame you want and the time fills itself in.
  • Trim conservatively: leave half a second of breathing room at each end so the cut never feels chopped mid-gesture.
  • Keep clips short. The tool re-encodes video in your browser, so trimming a 30-second segment is quick while a 20-minute one is not.
  • Remember the output has no audio. If you need sound, trim for timing first, then extract the matching audio segment with the audio extractor on this site.

Frequently asked questions

How do I trim a video online with this tool?
Load your video, enter the start and end times (or pause at the moment you want and use the 'Use current time' buttons), preview the segment, then press 'Trim & download'. The tool re-encodes just that segment and downloads it — no software to install.
What format is the trimmed video?
The download is a WebM file at your clip's original resolution. This is an honest trade-off of the browser-based method: you get a universally playable file, but it is a re-encoded silent WebM rather than your original MP4 or MOV container.
Why does the output have no sound?
This tool records the picture through your browser's canvas and that path carries video only, not audio. If you need the sound too, use the audio extractor tool on this site to pull the audio from the same time range as a WAV file.
Is my video uploaded anywhere?
No. Your file never leaves your device — trimming happens entirely in your browser with local processing. There is nothing to sign up for and no server ever sees your footage.
Does trimming reduce video quality?
Re-encoding always involves a small quality cost, but this tool encodes at a generous 8 Mbps bitrate and your clip's full resolution, so short clips look essentially identical to the source. Keeping trims short is the best way to protect quality.
Can I trim on my phone?
Yes, on a recent mobile browser — pick the file from your gallery, set the times, and download the result. Keep trims short on phones, since re-encoding a long clip can be slow and drain battery.
What video formats can I upload?
MP4, WebM and MOV files work in any modern browser. Very unusual codecs or DRM-protected recordings may not play in the browser preview and cannot be trimmed here.
Is this video trimmer really free?
Completely free with no signup, no watermarks and no limits on how many clips you trim. It runs entirely on your device, so there are no server costs to pass on to you.
