What is OGG?
OGG is an open, patent-free container most often used for Vorbis or Opus audio. It gives good quality at low bitrates and is common in games, web apps and Linux software, but many car stereos and Apple devices do not play it.
What is MP4?
MP4 is the most widely used video container. It usually carries H.264 or H.265 video with AAC audio, and it plays on practically every phone, browser, smart TV and editing program, which makes it the safest choice for sharing and uploading.
Tips for converting OGG to MP4
- Converting a compressed file such as MP3 to a lossless format does not restore detail already removed; it only makes the file larger.
- For music, a lossless source (WAV or FLAC) gives the best result when you convert to MP4.
- Check that your player, car stereo or editing app supports MP4 before converting a whole library.
- Keep the original OGG file as a backup until you are happy with the converted audio.
