MP4 is one of the most widely used video formats, known for its excellent balance between video quality and file size. It’s compatible with almost all media players and devices, making it ideal for streaming, sharing, and storing videos. MP4 files can contain video, audio, subtitles, and images in a single container.
M4A is an audio file format developed by Apple, often used for songs and other audio content in iTunes. It is based on the AAC codec and offers high compression with minimal loss of quality. M4A is ideal for digital music files due to its smaller size and efficient storage.
