What is MP3?
MP3 is the classic compressed audio format. It removes sounds the ear barely notices to shrink files to roughly a tenth of CD size, and it plays on every phone, car stereo and music app, which is why it remains the default for music and podcasts.
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.
Tips for converting MP3 to OGG
- 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 OGG.
- Check that your player, car stereo or editing app supports OGG before converting a whole library.
- Keep the original MP3 file as a backup until you are happy with the converted audio.
