WebM Video Cutter
Trim WebM by time in your browser. Optional MP4 output for universal playback.
WebM is common for screen capture and HTML5. Trimming WebM shortens without re-recording. Export WebM or MP4 depending on audience. All processing is client-side.
When to use WebM Video Cutter vs other formats
Choose WebM-focused trimming for VP8/VP9 assets. For mixed devices, MP4 after trim is often simplest.
Compatibility
Safari on iOS may prefer MP4 — pick MP4 output when needed.
Quality considerations
Check cursor and text at cut points; screencasts may need extra frames for clarity.
Example use cases
- Remove silence from a WebM tutorial.
- Split a long WebM into chapters.
- Clip a bug repro for a ticket.
Best practices
- Export MP4 for iOS viewers.
- Preview keyboard and mouse actions near cuts.
- Use decimal seconds for tighter edits.
Common use cases
- Documentation — Short how-to segments.
- Marketing — Hero clips under duration limits.
- Cross-platform — MP4 handoff for review.
- Storage — Smaller clips from long captures.
- QA — Isolate reproduction steps.
