Trim Video Online Free

Cut a clip to the part you want with a fast, quality-preserving trim — no re-encode when possible.

Trimming is the most common video edit — keep the good part, drop the rest. The Media Manipulator video trimmer lets you set a start and end time numerically or drag a visual range, then performs a fast stream-copy cut that preserves the original quality with no re-encode when possible. Output defaults to MP4.

What this tool does

  • Cuts a video to a single start-to-end range.
  • Prefers a lossless stream-copy (no re-encode, no quality loss, very fast).
  • Falls back to a re-encode automatically when the container/codec needs it.
  • Lets you pick the range numerically or with a visual scrubber.

Why it matters

  • Removing dead air at the start/end makes any clip better.
  • A lossless trim keeps the original quality and is nearly instant.
  • Trimming first makes converting, compressing, or GIF-ing faster.

Common use cases

Cut the intro/outro

Drop the boring beginning or end of a recording.

Clip a highlight

Keep just the moment you want to share.

Prep for upload

Trim before posting to social platforms.

Shorten for GIF

Advanced details
  • The fast path is a stream-copy: ffmpeg seeks to the start and copies the segment without re-encoding, so there is zero quality loss.
  • Stream-copy cuts at the nearest keyframe; tick "Re-encode for a frame-accurate cut" when you need the exact frame.
  • MP4 re-encode fallback uses H.264 + AAC + yuv420p + faststart.

Frequently asked questions

  • How do I trim a video online?

    Upload it, set a start and end time (or drag the visual range), and download the trimmed clip.

  • Does trimming reduce quality?

    No — the default lossless stream-copy keeps the original quality. Only the frame-accurate re-encode option re-compresses.

  • Why does my cut start slightly early?

    Lossless cuts snap to the nearest keyframe. Enable the frame-accurate re-encode option to cut at the exact time.

  • What output format do I get?

    MP4 by default; you can also choose MOV or WebM.

  • Is it free?

    Yes — no watermark, no signup. Files are deleted within 24 hours.
