MP3 to OGG Converter
Convert MP3 to OGG for game engines, Minecraft resource packs, Linux apps and the web. The page writes classic OGG Vorbis by default, the format Godot, Unity and Minecraft read, and can switch to OGG Opus for the smallest web audio. Convert a whole sound library in one batch, right in your browser, with no upload.

How to convert MP3 to OGG
Step 1: Drop your MP3 files on the box above. A full folder of sound effects is fine.
Step 2: Keep OGG codec on Vorbis for games, or pick Opus for websites and voice.
Step 3: Pick a Bitrate: 128 kbps suits most game audio, 192 kbps for music tracks.
Step 4: Press Convert and download the OGG files as a ZIP.
Good to know
Settings explained
- Bitrate
- 128 kbps is fine for speech, 192 kbps for music, 320 kbps is the MP3 maximum.
- OGG codec
- Godot, Unity and older players need Vorbis. Vorbis uses the FFmpeg engine (≈31 MB, downloaded once).
- Opus: Smaller
- Vorbis: Games, older players
Formats
Batch-friendly: add many files and they are processed one after another — if one fails, the rest still finish.
How it runs
- Hardware video engine
- Video is decoded and encoded by your device’s media hardware through WebCodecs — usually several times faster than real time.
- FFmpeg (when needed)
- Older formats and a few filters use FFmpeg compiled to WebAssembly. It downloads once (about 31 MB) the first time it is needed and is cached for offline use.
Vorbis or Opus: which goes inside the OGG?
Choose Vorbis when a game engine or mod tool will import the file: it is the codec people mean by “OGG” and the one engines expect. Choose Opus when the file is for a website, an app or speech: it sounds better at low bitrates and modern browsers play it, but many engines and older players cannot open it.
| OGG Vorbis (default) | OGG Opus | |
|---|---|---|
| Imported by Godot, Unity, Minecraft packs | Yes | Often not |
| Sample rate | Kept from the MP3 (usually 44.1 kHz) | Always 48 kHz |
| Best at | 96–192 kbps music and effects | 64–96 kbps voice and web audio (the lowest setting here is 64 kbps) |
| Encoder used here | FFmpeg libvorbis (downloads once, about 31 MB) | Your browser’s own encoder where available |
What is an OGG Vorbis file?
An OGG Vorbis file is Vorbis-compressed audio in an Ogg container, both made by the Xiph.Org Foundation as free alternatives to MP3. Game developers adopted it early because shipping it needs no licence, which is why so many engines, mod tools and open-source apps read .ogg and some prefer it over MP3.
The Opus codec can live in the same .ogg container, which is why the page lets you choose.
Which bitrate to choose for OGG Vorbis
Vorbis is encoded in quality mode, which spends more bits on complex sounds and fewer on simple ones. The bitrate you choose sets the quality level; the actual average depends on the audio, and the result card shows what was written.
| Bitrate setting | Vorbis quality | Good for |
|---|---|---|
| 64 kbps | q0 | Ambient loops, background voice, small mobile games |
| 96 kbps | q2 | Footsteps, UI clicks and other short effects |
| 128 kbps (default) | q4 | Most game audio and dialogue |
| 192 kbps | q6 | Music tracks and soundtracks |
| 256 kbps | q8 | High-quality music |
| 320 kbps | q9 | Masters, when size does not matter |
Does converting MP3 to OGG improve quality?
No. The MP3 is decoded and re-encoded, so the OGG can only be as good as the MP3, minus a small extra loss. Pick a bitrate at or above the MP3’s to keep that loss inaudible. If you still have the original WAV, convert it with WAV to OGG instead and skip the MP3 generation entirely.
Mass-convert MP3 to OGG for a game or mod
- Drop the whole sound folder at once; every file gets the same codec and bitrate.
- Use Download all to get one ZIP, then unpack it into your project’s assets folder.
- Keep the file names: each OGG is named after its MP3, so references in your code or sound definitions only need the new extension.
- For Minecraft resource packs, use Vorbis; Opus files will not play there.
Tips & troubleshooting
Sound effects that will be placed in 3D space are usually mono. Set Channels to Mono under Advanced settings and the files shrink too.
Effects at very different volumes? Run them through normalize audio before converting.
Need just a slice of a track as a loop or effect? Cut it first with the MP3 cutter.
Converting OGG back for a player that wants MP3? Use OGG to MP3.
MP3 to OGG Converter FAQ
Is OGG Vorbis better than MP3?
At the same bitrate, Vorbis generally sounds a little better than MP3, especially below 128 kbps, and it is royalty-free. MP3 still plays on more devices. For games, OGG Vorbis is the usual choice; for car stereos and old players, MP3.
Which OGG format do Minecraft, Godot and Unity need?
OGG Vorbis, the default on this page. Minecraft resource pack sounds must be Vorbis, and Godot and Unity both import .ogg Vorbis files directly. Choose Opus only for web or app audio.
How do I mass-convert MP3 to OGG?
Drop all the MP3s on this page at once, keep Vorbis and your bitrate, and press Convert. Each file is converted in turn, and Download all saves them as one ZIP.
Does converting MP3 to OGG improve quality?
No. Converting cannot restore what the MP3 removed. It only changes the format, so choose a bitrate at or above the MP3’s and keep your originals.
Why does the first Vorbis conversion take longer?
Browsers have no built-in Vorbis encoder, so the page loads FFmpeg’s libvorbis the first time (about 31 MB). It is cached afterwards, and Opus conversions normally use the browser’s own encoder instead.
