About the MP3 to OGG
MP3 to OGG converts MP3 audio into OGG, right in your browser. MP3 is the most universal audio format — it plays on virtually every phone, car stereo, browser and app, which is why it is still the safest choice for sharing. OGG (Vorbis) is a free, open format with good quality at small sizes, common in games and open-source software.
Converting MP3 to OGG gives you a free, open format that games and open-source apps prefer. Both formats are compressed, so pick a higher bitrate (192–320 kbps) to stay as close to the original as possible — converting cannot add back quality that lossy compression already removed. Everything runs on your device with a WebAssembly build of ffmpeg, so your file is never uploaded — it is private, free and has no watermark. The audio engine is downloaded once (shared with the other audio and video tools) and then cached, so repeat conversions start quickly.
Frequently asked questions
Is my MP3 file uploaded?
No. The conversion runs entirely in your browser with ffmpeg (WebAssembly). Your file never leaves your device.
Will I lose quality converting MP3 to OGG?
Both formats are compressed, so pick a higher bitrate (192–320 kbps) to stay as close to the original as possible — converting cannot add back quality that lossy compression already removed.
What bitrate should I choose?
For OGG, 192 kbps is a good balance and 320 kbps is near-transparent. Lossless targets (WAV, FLAC, AIFF) ignore bitrate and keep full quality.
Can I convert more than one file?
Convert them one after another — each stays private on your own device, with nothing uploaded.
