Why MP4 Is the Universal Standard
MP4 uses H.264 video compression and AAC audio — two codecs that are supported natively by every modern device and platform. Unlike AVI, MKV, or MOV, which may use proprietary or inefficient codecs, MP4 is designed for maximum compatibility and efficient file size.
When to Convert to MP4
- Video won't play on your phone → convert to MP4.
- Video won't upload to social media → convert to MP4.
- Video file is too large → MP4's efficient compression reduces size.
- Sending a video to someone → MP4 guarantees it plays on their device.
