What is MP4?

MP4 is a digital multimedia container format that can store video, audio, subtitles, and still images. It uses advanced compression codecs like H.264 (AVC) and H.265 (HEVC) to achieve high quality at manageable file sizes.

The format is based on Apple's QuickTime (MOV) format and has become the international standard for video distribution. MP4 files are used everywhere—from YouTube and Netflix to smartphones and professional video production.

Universal Standard: MP4 is supported by every major platform, browser, and device, making it the safest choice for video distribution.
