Convert OGG to MP3
You convert OGG to MP3 by dropping the .ogg file into the box on this page and clicking the button; the MP3 lands in your downloads when the local encode completes. The decode and re-encode both happen as WebAssembly in your browser, so the file is never sent to a server.

Why convert OGG to MP3?
OGG is the open, royalty-free corner of the audio world, which is why it turns up where licensing matters: sound and music ripped out of games like Minecraft or built in Unity and Unreal, Spotify's own internals, and a long list of open-source tools. It is a perfectly good lossy format, but the mainstream never embraced the .ogg extension, so the moment you want that audio in a car system, a stock video editor, a podcast tool or a picky upload form, it bounces. Converting to MP3 is the standard way to get game and open-source audio into ordinary consumer software without fighting plugin support.
What is OGG?
OGG is the Xiph.Org container, in practice almost always carrying Vorbis-compressed audio: the open, royalty-free alternative that game engines, Wikipedia and open-source tooling adopted in the 2000s. Quality per kilobyte is solid, but device support never caught up to MP3, so .ogg files regularly need converting before they play in cars, on older hardware or inside picky upload forms.
What is MP3?
MP3 is the audio format that ate the world in the late 1990s, and it remains the most universally supported way to store sound: lossy compression at roughly a tenth of CD size, playable on literally anything with a speaker. Newer codecs like AAC and Opus beat it on quality per kilobyte, but no format comes close to its compatibility across car stereos, ancient MP3 players, browsers, editing software and upload forms.
Quality and what to expect
This is a lossy-to-lossy transcode, so it is a second generation of loss: the LAME encoder works from already-compressed Vorbis audio, not from a pristine source, and produces MP3 at a high variable bitrate (around 190kbps equivalent). For typical OGG sources that started at a decent bitrate the added loss is hard to hear, but stacking two lossy codecs is never free, so do not round-trip a file back and forth. If you have access to an uncompressed original, encoding from that instead gives a cleaner result. Vorbis-specific comment tags are not carried into the MP3.
OGG to MP3 FAQ
Why will not my .ogg file just play everywhere already?
OGG Vorbis is technically solid and royalty-free, but mainstream players, car systems and many editing apps never added support for the container. MP3 is the lowest common denominator they all accept, which is why this conversion exists.
Does converting OGG to MP3 lose quality?
A little. Both formats are lossy, so this is a second generation of compression and some detail is shed in the re-encode. At the bitrate used here it is hard to notice for most material, but avoid repeatedly converting the same audio between lossy formats.
Can I convert game audio I extracted from a title?
Technically yes, the converter handles any standard OGG Vorbis file. What you do with extracted game assets is between you and that game's license, but the conversion itself runs fine on the .ogg files engines like Unity and Unreal use.
Is the audio sent anywhere to be converted?
No part of it leaves your device. The Vorbis decoder and MP3 encoder are compiled to WebAssembly and run inside your browser tab, so the conversion happens on your machine with no upload step at any point.
