About this tool

Convert MOV videos to MP4 locally in your browser. The conversion runs entirely on your device so your video stays private and ready to play on any MP4-compatible player.

Why convert MOV to MP4?

MOV is a common Apple video container, but it is less widely supported than MP4 across web players, social apps, and older devices. Converting to MP4 improves compatibility while keeping your original video content local to your browser.

How conversion works

Upload a MOV file and the tool uses a browser-based FFmpeg engine to remux and re-encode the file into an MP4 container. The entire process happens on your device, without uploading your video to a server.

Privacy and compatibility

  • The MOV file is processed locally in the browser; no data is sent to a remote service.
  • The output MP4 uses widely supported codecs so it plays in nearly every modern browser and media player.
  • If the source MOV contains audio, the audio is preserved in the converted MP4.

Frequently asked questions

Does my video leave my device?
