Turn OGG and OPUS files into MP3s that every player and editor opens.
OGG files show up in game folders, open-source apps, sound-effect libraries, Linux recordings and voice messages saved from messengers (often as .ogg or .opus with Opus sound inside). Many car stereos, older players, video editors and upload forms don’t accept them. This page decodes Ogg Vorbis and Ogg Opus in your browser, using a built-in Vorbis decoder where the browser has none, and encodes MP3 at the bitrate you choose. Batches work, and nothing is uploaded.
How to convert OGG to MP3
- Add the .ogg, .oga or .opus files.
- Choose 128 kbps or Mono for voice messages, 192 kbps for music and game soundtracks; trim if you only need part of a track.
- Convert and download the MP3s, or one ZIP.
What happens to quality, size and metadata
Vorbis and Opus are lossy, so the MP3 is a second lossy generation. Both are efficient: a 96 kbps Vorbis or 32 kbps Opus voice note can sound fine, while the same bitrate in MP3 would not. So pick a higher MP3 bitrate than the source: 128 kbps for speech, 192 kbps or more for music. Opus always decodes at 48 kHz, so MP3s from Opus files are 48 kHz. Vorbis keeps its sample rate when MP3 supports it. Loop points used by games, and Vorbis comment tags, are not carried over; the title tag is the file name.

OGG vs MP3
| Full name | OGG | MP3 |
|---|---|---|
| Full name | Ogg (Vorbis or Opus audio) | MPEG-1 Audio Layer III |
| Introduced | 2003 | 1993 |
| Defined by | Xiph.Org · RFC 3533 | MPEG · ISO/IEC 11172-3 |
| Compression | Lossy or lossless | Lossy |
| Chrome / Edge | Yes | Yes |
| Safari | Yes | Yes |
| Firefox | Yes | Yes |
| Windows | — | Yes |
| iPhone / iPad | — | Yes |
| Android | — | Yes |
| Typical use | Game audio, voice messages, open-source software and web audio. | Music, podcasts, voice recordings and any audio that has to play on every device. |
OGG Ogg is an open container from Xiph.Org (RFC 3533), most often holding Vorbis or Opus audio. Both codecs are free of patents and sound good at low bitrates. Games, Linux apps and voice messengers use it, but many players, car stereos and editors outside the browser still don’t open it.
MP3 MP3 is the lossy audio format standardised by MPEG in ISO/IEC 11172-3 (1993). Its patents have expired, and practically every player, car stereo, phone and editing app plays it. At 192 kbps most listeners cannot tell it from the original on typical speakers or headphones.

Without this site
No major operating system converts OGG out of the box. On Windows, Mac and Linux, the free Audacity opens Ogg Vorbis files and exports MP3 with File › Export Audio; VLC’s Media › Convert / Save with “Audio – MP3” handles both Vorbis and Opus. Windows 10 and 11 can play some OGG files in Media Player, but not convert them. Phones have no converter for OGG.
Troubleshooting
- The .ogg file is actually a video. Ogg can also hold Theora video. Only the sound is converted.
- FLAC inside Ogg. Rare, but it works if your browser decodes it; otherwise you get a clear message.
- Voice message sounds muffled. Messengers record at low Opus bitrates. The MP3 can’t improve it; Mono 128 kbps is plenty.
- Game music should loop. MP3 has no loop points; the MP3 plays once from start to end.
Questions and answers
How do I convert OGG to MP3?
Add the OGG file on this page, choose a bitrate (192 kbps for music, 128 kbps for speech) and press Convert. The file is decoded and encoded to MP3 in your browser, then downloaded. It works in Chrome, Edge, Firefox and Safari, on computers and phones.
Can I convert OPUS voice messages to MP3?
Yes. Voice messages saved from messengers are usually Opus in an Ogg file (.ogg or .opus). Add them here, choose Mono and 128 kbps, and convert. The messages are processed on your device, which matters for private conversations. Several messages can be converted together and downloaded as a ZIP.
Why won’t my phone or car play OGG files?
OGG is an open format popular with software and games, but many devices only include decoders for MP3 and AAC. iPhones play some OGG audio only in recent versions, and many car stereos and older players never do. MP3 is the safe choice for those.
Is OGG better quality than MP3?
At the same bitrate, Vorbis and especially Opus usually sound better than MP3, so OGG files can be smaller for the same quality. Converting an OGG to MP3 won’t improve it; choose a generous MP3 bitrate so the result stays close to the original.
