MP3 vs OGG
MP3 (MPEG-1 Audio Layer III) is plays on practically every device, car stereo and app made since the late 1990s. OGG (Ogg container (Opus or Vorbis)) is an open, royalty-free format used by Discord, WhatsApp voice notes, Spotify and many games.
OGG with the Opus codec gives noticeably smaller files than MP3 at the same perceived quality, which is why games, web apps and messaging services use it.
MP3 to OGG makes sense when a game engine or web app requires Ogg. Pick a bitrate at or below the MP3's original.
Settings that work
- Voice: 48–64 kbps Opus is already clear.
- Music: 128 kbps Opus is roughly comparable to 192 kbps MP3.
Questions
How do I convert MP3 to OGG?
Drop your MP3 files into the converter above. OGG is pre-selected; press Choose files and each converted file downloads automatically.
Will converting MP3 to OGG lose quality?
Some, as with any conversion between two lossy formats. At 128 kbps or higher the difference is inaudible for most listeners.
Is it safe to convert private recordings here?
Yes. Conversion runs entirely in your browser with the Web Audio API and a JavaScript encoder, and nothing is uploaded to a server.
