How to trim video online

  1. 1

    Upload your video

    Choose a file from your device or drag it into the trimmer. A visual timeline and filmstrip preview help you see where the clip should begin and end.

  2. 2

    Set the start and end points

    Drag the trim handles or use the playhead controls to select the exact section you want to keep. This makes it easy to cut a longer recording down to a shorter clip for sharing or editing.

  3. 3

    Trim and download

    Export the selected section and download the trimmed video when it is ready. The process runs in your browser, so you can cut video online without sending the full file to a remote service.

Understanding the settings

If the output format stays the same as the input, trimming can often use stream copy, which is much faster and avoids re-encoding the video. That is the best option when you only want to remove extra footage without changing quality. If you switch formats, the video must be re-encoded, which gives more exact control but takes longer. Trimming is often the first step before compressing, especially when the easiest way to reduce file size is simply to remove the part you do not need.

Best settings for common goals

Fastest trim with no quality loss

Keep the output format the same as the input whenever possible.

That allows stream copy, which is dramatically faster and avoids re-encoding the media.

Cleaner social clip

Trim the clip first, then run compression only if the exported segment is still too large.

Removing unused footage before compression usually saves more time and produces a better final result than compressing the entire original first.

Practical guidance

Trim before you optimize

Trimming is often the smartest first step because it removes content you never wanted to keep. That usually reduces file size, processing time, and later editing complexity all at once.

  • Use trim first for highlights, teasers, reels, and support clips.
  • Use copy mode when speed matters more than frame-perfect precision.
  • Re-encode when the start and end points need to feel cleaner to the viewer.

Compatibility, privacy, and limitations

Keyframe accuracy

Lossless stream-copy trims are fast, but they align to nearby keyframes rather than every exact frame. If you need more precise cuts, forcing re-encoding is often the better choice.

Privacy explanation

Trim jobs often involve recordings that contain extra personal or confidential footage around the part you actually need. Local trimming helps remove that excess without uploading the raw original anywhere.

Things to keep in mind

  • A single trim operation extracts one continuous range rather than building a multi-cut timeline.
  • Exact frame-level cuts are harder to guarantee in copy mode because they depend on how the source file was encoded.
