MP4 Video Cutter
Trim MP4 by time in your browser. Free, no upload. Client-side only.
MP4 (often H.264) is the default for sharing. Trimming MP4 extracts a segment between two timestamps — ideal for phone clips, downloads, and exports that must stay MP4-friendly. You choose output format when supported.
When to use MP4 Video Cutter vs other formats
Use this page when your source is MP4-first. WebM suits web-only pipelines; MOV fits some Apple editors. After trimming you can still export MP4, WebM, or MOV.
Compatibility
Trimmed MP4 (H.264) plays on phones, desktops, and TVs. Match duration limits on each platform before publishing.
Quality considerations
Exported quality depends on source and encoder settings. Preview the segment before final export; very short clips may need looser handles for smooth edits later.
Example use cases
- Extract a highlight from a long MP4 recording.
- Shorten a clip to fit a platform duration cap.
- Split one MP4 into multiple uploads by cutting repeatedly.
- Remove unwanted intro or outro from an MP4.
Best practices
- Use preview to align audio and video at cut points.
- Export MP4 when unsure about playback targets.
- Keep a master copy before heavy re-editing elsewhere.
- Note platform minimum and maximum lengths for shorts.
Common use cases
- Social highlights — Short segments for feeds and stories.
- Meetings — One agenda item from a long recording.
- Ads — Exact duration for placements.
- Education — Single concept from a lecture MP4.
- Archiving — Smaller clips beside full masters.
