How Does the MOV to MP4 Converter Work?
The CompressFly MOV to MP4 converter decodes supported video and audio from the QuickTime container, re-encodes the picture as H.264 and available audio as AAC, and creates an MP4 file. This is a full conversion rather than an extension change.
Conversion runs directly in your browser. Your MOV video is not uploaded to a server, and the completed MP4 file downloads from the browser to your device.
What "directly in your browser" means
- Your MOV video is not uploaded to a server.
- Video conversion runs locally on your device.
- The completed MP4 video downloads directly from your browser.
