MOV to MP4

Convert MOV to MP4 online for free — turn iPhone, QuickTime and camera MOV files into MP4 that plays everywhere. When the video is already H.264 or HEVC it's copied without re-encoding, so conversion takes seconds with no quality loss. Runs privately in your browser.

100% private — your video is processed on your device, never uploaded. Conversion happens on your device; nothing is uploaded.

100% private — runs in your browser

Processing uses your browser’s built-in video encoders (WebCodecs) through the open-source Mediabunny library — your video is never uploaded. Works best in recent Chrome, Edge and Safari; the output is kept in memory, so very large files (several GB) may need a computer with plenty of RAM.

How to convert MOV to MP4

  1. Drop your MOV file in the box.
  2. Click Convert to MP4.
  3. Preview the MP4.
  4. Download it.

What you can use it for

  • Share iPhone videos with Windows and Android users
  • Upload QuickTime recordings to sites that need MP4
  • Make MOV files play in more editors and players
  • Convert screen recordings from QuickTime

Frequently asked questions

Does converting MOV to MP4 lose quality?

Usually not — most MOV files already contain H.264 or HEVC video, which is copied straight into the MP4 without re-encoding.

Will HEVC (H.265) iPhone videos play everywhere after converting?

They become MP4 files, but some older Windows PCs can't play HEVC. Use Compress Video to re-encode as H.264 for maximum compatibility.

How long does it take?

Copying without re-encoding takes seconds even for long videos.

Is my video uploaded?

No. The video is read and encoded by your own browser using its built-in video encoders, so it never leaves your device — even large or private videos stay private.

Is there a file size limit?

There's no upload limit. The finished video is held in memory before download, so files up to a few GB work on most computers; very large files need more RAM.

Which browsers work?

Recent Chrome, Edge and Safari work best (they have hardware video encoders). Firefox 130+ works for most files.
