To convert MP3 to OGG for free, drop your MP3 files above, choose a bitrate (96 to 320 kb/s) and download OGG Vorbis files — the open audio format expected by Minecraft resource packs and favoured by game engines such as Godot. Files up to 95 MB are converted on our compute server (native ffmpeg) and erased as soon as the result is sent; larger files, or when the server cannot take the job, are converted in your browser and never leave your device.
Who needs OGG files
- Minecraft (Java Edition) resource packs: custom sounds and music must be .ogg files (Ogg Vorbis). Sounds that should get quieter with distance need to be mono; stereo files play at the same volume everywhere.
- Game developers: Godot, Unity and most engines import Ogg Vorbis, which loops cleanly and has no licensing constraints. Godot's documentation recommends Ogg Vorbis for music.
- Open-source projects and Linux software that prefer patent-free formats.
- Web and app developers who want a free format alongside MP3.
Choosing the bitrate
| Bitrate | Use it for |
|---|---|
| 96 kb/s | Sound effects, voice lines, short UI sounds |
| 128 kb/s | Background music in games, the usual balance |
| 192 kb/s (default) | Music that is listened to closely |
| 256 to 320 kb/s | Little audible gain from an MP3 source; mostly larger files |
Converting MP3 to OGG decodes one lossy format and encodes another: keep the bitrate at or below that of your MP3, and start from the original WAV or FLAC when you have it — the result will be cleaner.
Good to know
- The sample rate and channels of the MP3 are kept as they are. To turn a stereo sound into mono (for Minecraft positional sounds), mix it down in an audio editor such as Audacity first.
- Many files at once, downloaded one by one or in a ZIP.
- ID3 tags (title, artist) are not guaranteed to carry over; check them if your project relies on them.
- Need the opposite? OGG to MP3 converts OGG and Opus files back to MP3.
