Why convert MP3 to OGG?
OGG Vorbis is the preferred audio format of many game engines and open-source apps because it is royalty-free and loops cleanly.
- MP3: lossy: some detail is removed.
- OGG: open and royalty-free.
- OGG: good quality at medium bitrates.
160 kbps OGG is a good default for game music and sound effects.

Does converting MP3 to OGG lose quality?
Both formats are lossy, so converting adds a small amount of loss. Use the same or a higher bitrate than your MP3 (192 kbps covers most files) and the change is inaudible.
How long does it take?
A few seconds for a song, and under a minute for an hour-long recording on most computers.
What is an MP3 file?
MP3 is the most widely used audio format in the world. It removes sounds people are unlikely to hear, shrinking a song to about a tenth of its CD size. At 192 kbps or higher most listeners cannot tell it from the original, and every device plays it. Its patents expired in 2017, so it is now free to use.
What is an OGG file?
OGG files usually contain Vorbis, a free, open audio codec. Spotify streamed in Vorbis for years, and many games and Linux apps use OGG for music and sound effects.
Frequently asked questions
Do I have to pay or sign up to use the MP3 to OGG converter?
No. There is no account, no payment and no watermark. The only limit is 1 GB per file, set by what browsers can handle.
Is my file uploaded to a server?
No. The converter runs inside your browser using WebAssembly, so your file is processed on your own device and never sent to us or anyone else.
Will the OGG sound as good as the MP3?
Both formats are lossy, so converting adds a small amount of loss. Use the same or a higher bitrate than your MP3 (192 kbps covers most files) and the change is inaudible.
Can I convert OGG back to MP3?
Yes, use the OGG to MP3 converter.
An MP3 sounds thin or has artefacts. What should I do?
It was probably encoded at a low bitrate. Re-encoding cannot restore it; find a better source.
Does it work on iPhone and Android?
Yes, in Safari, Chrome and other modern mobile browsers. Short files work best on phones; for long or high-resolution videos a computer is faster.
