Joined on your device. Nothing is uploaded. Keep clips short — desktop recommended.
Note: videos are re-encoded so different sources can be joined. This is CPU-intensive — best with short clips on a desktop.
Frequently asked questions
Are my files uploaded to a server?
No. Everything is processed entirely inside your browser. Your files never leave your device or get sent anywhere.
Why is video merging slower?
Videos are re-encoded so clips from different sources can be joined cleanly. This is CPU-intensive — short clips on a desktop work best.
What output do I get?
A single MP4 file (H.264 video, AAC audio) that plays everywhere.
