À propos de cet outil: Fusionner des vidéos MP4
Assemblez des clips MP4 sur une timeline, ajustez les coupes image par image et exportez une seule vidéo dans votre navigateur.
Merge MP4 Videos lets you build one final MP4 from multiple clips directly in your browser. Arrange clips on a timeline, trim each segment, adjust scale and positioning per clip, and export the combined result without uploading anything to a server.
This tool is built for practical client-side editing workflows: quick assembly, frame-by-frame timing tweaks, and manual fit adjustments when one clip is slightly narrower, taller, or offset compared to the others.
Best for
- Combining several MP4 clips into one deliverable
- Fixing slight framing mismatches between clips
- Browser-only editing when privacy matters
Technical notes
Because timeline edits, scaling, and per-clip fitting change the actual rendered frame, the final merged MP4 is re-encoded locally in your browser using WebCodecs. That keeps processing private while enabling frame-accurate visual adjustments.

How it works
Unlike converters that upload files to a cloud server, Skyron Tools processes them directly in your browser using browser-native codecs, WebAssembly, or local JavaScript workers as appropriate.
