Add files from where they live
Drop a OGG file on the box, browse for it, or import it from Dropbox, Google Drive or a link. You can add more files later, and each file gets its own result.
Free OGG to MP3 converter
Convert OGG to MP3 online. Add a file, confirm MP3 and download it. A single file needs no account.
Converting OGG to MP3 makes open-source audio playable on the many devices that ignore it, from iPhones and iTunes to car stereos and smart speakers. Both formats are lossy, so the Vorbis or Opus stream is decoded and compressed again, which costs a small amount of quality in exchange for a file that works nearly everywhere.
Transfers use HTTPS, and files converted on the free tier are deleted within 24 hours, so the result is not a long-term archive. Quality depends on the source file, so open the MP3 file once before you share it.
FromOGGLossy
Ogg (Xiph.Org container, usually Vorbis audio)
An open, patent-free container from the Xiph.Org Foundation. An .ogg file usually holds Vorbis audio and sometimes Opus, both lossy, and it is common in games, Linux applications and the media files on Wikipedia.
ToMP3Lossy
MP3 (MPEG-1 Audio Layer III)
A lossy audio format whose patents have expired and whose support is close to universal. Hardware and software that have never heard of Vorbis or Opus, including Apple's apps and most car stereos, read it without extra codecs.

A progress bar shows the file moving through the conversion. If you picked the wrong file, cancel and start again.
Download it or hand it on
Save the MP3 file, copy a share link or convert it to another format. Free-tier output expires on its own after 24 hours.
What changes
- Vorbis or Opus audio is re-encoded with the MP3 codec, an older design that needs a higher bitrate to reach similar clarity.
- Playback support expands from browsers, Android, VLC and game engines to almost every consumer device, including Apple's Music app and QuickTime.
- Vorbis comments, which are free-form text labels, are translated into fixed ID3 frames, so standard fields transfer and custom ones can be lost.
- Multichannel audio is reduced to stereo, since Vorbis and Opus streams can hold surround sound and ordinary MP3 files are limited to two channels.

What are the limits for OGG to MP3?
Size
The upload box shows the live size limit before you add a file. Signing in raises it, and paid plans raise it further.
Formats
OGG in, MP3 out. Pick another output on the converter if you need a different format.
Privacy
Files are encrypted in transit over HTTPS and processed on indox infrastructure.
Deletion
Free-tier files are deleted automatically within 24 hours after the job finishes.
Limits worth knowing
- Each lossy generation removes more detail. A low-bitrate OGG, such as game audio or a voice message, shows the damage most clearly.
- Not every .ogg file is audio alone. Some contain Theora video, in which case only the sound can become an MP3.
- Tag conversion is mostly but not always complete: multiple artists, unusual field names and embedded artwork are the items most likely to go missing.
- Game audio that loops cleanly as OGG may gain a short gap as MP3, because MP3 encoders pad the start and end.

OGG to MP3 FAQs
Does converting OGG to MP3 lose quality?
Yes, a little. Vorbis and Opus have each already removed part of the original sound, and MP3 removes a different part on top, so the errors add up. Starting from a well-encoded music file, you are unlikely to notice. Starting from a tiny speech-optimised Opus file, the MP3 can sound rougher and will be considerably larger.
Why won't OGG files play on my iPhone or Mac?
Because Apple's own apps have historically not included a Vorbis decoder. Music, QuickTime Player and the Files preview generally refuse .ogg files, although support has been creeping into recent system versions and varies between them. A third-party player such as VLC handles OGG on both platforms. Converting to MP3 is the fix when you need Apple's built-in apps.
Is OGG better than MP3?
At the same bitrate, generally yes. Vorbis is a newer design that most listening tests rate above MP3, particularly below about 128 kbps, and Opus is better still for speech and low bitrates. MP3's advantage is purely practical: nearly every device plays it. Quality is a reason to keep OGG, and compatibility is the reason to convert.
What is the difference between OGG, Vorbis and Opus?
OGG is the container, and Vorbis and Opus are codecs that can sit inside it. A file ending in .ogg almost always holds Vorbis, while Opus audio normally uses the .opus extension even though it is wrapped in the same Ogg structure. WhatsApp voice messages are a familiar example of Opus in Ogg. All of these reach MP3 by full re-encoding.
Will the song titles and artist names carry over to the MP3?
In most cases, yes. Title, artist, album, date, genre and track number have clear ID3 counterparts and are normally written into the MP3. Vorbis comments are looser than ID3, though, allowing any field name and repeated values, so custom tags, several artists listed separately and sometimes cover art may not make the journey intact.
Why is the MP3 larger than the OGG?
Because MP3 needs more bits than Vorbis or Opus to sound similar, so a sensible conversion uses a higher bitrate than the source had. An Opus voice recording at 24 kbps, for example, would sound poor as a 24 kbps MP3. The extra size adds no new detail; it only limits how much the second encoding takes away.
