Convert OGG to MP3
Drop an OGG file and get a widely-playable MP3 back, ready to share, stream, or play on any device. The first time you use this tool the audio engine downloads once (~24 MB); after that the browser uses its cached copy. Your file never leaves your device.
About OGG to MP3
OGG is a container that most often holds Ogg Vorbis audio, an efficient lossy codec. It is excellent quality for its size, but it is not as universally supported as MP3 — some players, car stereos, and editing apps cannot open it. Converting OGG to MP3 decodes the Vorbis stream and re-encodes it with libmp3lame at 192 kbps by default. Because both formats are lossy, there is a small additional quality cost from re-encoding, but the result plays virtually everywhere.
Is it private?
Yes. The converter is WebAssembly and browser APIs running on your own machine. Nothing is uploaded, stored, or seen by us. There is no server to send files to.
Frequently asked questions
- Is converting OGG to MP3 lossy?
- Yes. Ogg Vorbis is already a lossy format, and MP3 is lossy too, so re-encoding adds a small generation loss on top of what the OGG already discarded. The benefit is broad compatibility: MP3 plays on virtually any device or app, where OGG support is patchier.
- What kind of OGG files does this handle?
- The common case is Ogg Vorbis (a .ogg or .oga file). The audio engine also decodes Opus carried in an Ogg container, so most .ogg files convert cleanly to MP3.
- Are my files uploaded to a server?
- No. The conversion runs on your device using WebAssembly and browser APIs. Your file is never sent anywhere. The first time you use the tool the audio engine downloads once (about 24 MB); after that the browser uses its cached copy.
- Is it free, and do I need an account?
- It is free with no watermarks, no daily caps, and no sign-up. Drop a file, convert it, and download the result.
