How to convert MOV to MP4 for free

Why MP4 is the most compatible video format, and how to convert a QuickTime MOV locally in your browser.

By The Editorial Team · Reviewed by Engineering · Published 2026-03-20

MOV is Apple’s QuickTime container; MP4 is the near-universal one. Converting MOV → MP4 (H.264/AAC) makes a clip play almost anywhere without re-recording it.

How it works here

The conversion runs in your browser using a WebAssembly build of ffmpeg. Your video never leaves your device, and the engine downloads only the first time you use a video tool.

Tips

  • Large files take longer — conversion speed depends on your device.
  • To shrink the result, run Compress Video afterwards.
  • Only need the sound? Use Extract Audio or Video to MP3.

This is a converter, not a downloader — it works on files you already have.
