Trim Video Online – Cut Out the Part You Want to Keep

Remove the shaky start, the long ending or everything except the moment that matters. Your video is cut on your own device and keeps its original format.

How to trim a video

  1. Add your video. Drop an MP4, MOV, M4V, WebM or MKV file onto the box above, or tap to choose one.
  2. Mark the part to keep. Drag the start and end handles of the slider, type the times into Start and End, or pause the video and press Set start to current position and Set end to current position.
  3. Pick a cutting method. Fast takes seconds and keeps the original quality; Precise starts on the exact frame but takes longer.
  4. Press Trim video and download. Watch the trimmed clip on the page, check its new length and size, then download it.

Features

  • Three ways to set the cut: a two-handle slider, typed times in seconds or minutes:seconds, and buttons that take the current position of the player.
  • Live preview. Moving a handle jumps the player to that moment, and the tool shows how much of the video you are keeping.
  • Fast, lossless cutting that copies the streams without re-encoding – ideal for long recordings.
  • Frame-accurate cutting when you need the clip to start on an exact moment.
  • Same format out as in. MP4, MOV, M4V, WebM and MKV files are saved back in their own format.
  • Size before and after, a preview of the result and a Cancel button while it works.

Why use Fileora to trim videos

A video cutter shouldn't need your video on its server. Fileora trims the file inside your browser, so a clip from your phone, a screen recording or a lecture never leaves your device. There's no upload queue, no watermark on the result, no account and no limit on how many videos you cut.

It works in current versions of Chrome, Edge, Firefox and Safari, on computers and on phones.

Choosing between Fast and Precise

Start with Fast. For most jobs – cutting a long recording down to the part you want, dropping a boring intro, or splitting off the end of a clip – a start that is a second early doesn't matter, and Fast is finished almost instantly without any loss in quality. Use Precise when the first frame matters, for example when a clip must start exactly on a word or a beat. Precise encodes every frame of the clip on one processor core, so for HD video it runs several times slower than real time: a 30-second 1080p clip can take a few minutes.

Trimming is also the best first step before other edits. A shorter clip is quicker to compress and ends up smaller. If you want to share the clip without its sound, you can mute the video next, and to save the soundtrack as audio, use MP4 to MP3.

Frequently asked questions

How do I trim a video?

Add the video, then drag the two handles of the slider to mark the part you want to keep – or type the start and end times, or play the video and press Set start to current position and Set end to current position. Choose Fast or Precise and press Trim video.

What is the difference between Fast and Precise?

Fast copies the video and sound exactly as they are, so it finishes in seconds and the quality doesn't change at all. The catch is that it can only start a clip on a keyframe, a full picture that videos store every few seconds, so your clip may begin up to a few seconds before the start you chose. Precise re-encodes the clip so it starts on the exact frame, which is slower and very slightly lowers the quality.

Why does my trimmed clip start a little early?

That's the Fast method snapping to the nearest keyframe before your start time. Most phone videos have a keyframe every one or two seconds, so the difference is usually small. If you need the cut to be exact, choose Precise and trim again.

Will the video keep its format and quality?

Yes, the trimmed file uses the same format as the original: an MP4 stays an MP4, a MOV stays a MOV, and WebM and MKV stay WebM and MKV. With Fast the picture and sound are untouched. With Precise the clip is re-encoded at high quality – H.264 and AAC for MP4, MOV and MKV, VP8 and Opus for WebM.

Is my video uploaded?

No. The video plays and is cut inside your browser using a WebAssembly build of FFmpeg. Nothing is sent to a server, so private recordings stay on your device and there is no upload wait.

Why is there no preview of my video?

Some browsers can't play every format – Safari, for example, doesn't play MKV files. You can still trim the video: type the start and end times (leave the end empty to keep everything to the end) and the tool cuts it all the same.

How precise can the start and end times be?

You can type times in seconds, such as 12.5, or in minutes and seconds, such as 1:05.5, down to a tenth of a second. The slider moves in tenths of a second too, and dragging it jumps the preview to that moment so you can see where you are.
