How Does the MPEG to MP4 Converter Work?
The CompressFly MPEG to MP4 converter decodes supported video and audio from an MPEG or MPG file, re-encodes the picture as H.264 and available audio as AAC, and creates an MP4 output. You can keep the source dimensions and frame rate or select different settings.
Conversion runs directly in your browser. Your MPEG 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 MPEG video is not uploaded to a server.
- Video conversion runs locally on your device.
- The completed MP4 video downloads directly from your browser.
