About the MP3 format
MP3 (MPEG-1 Audio Layer III) is the most widely supported audio format there is: every phone, car stereo, browser and player reads it. It is lossy, storing music at a fraction of the size of the original by removing detail the ear is least likely to notice. At 192 kbps or more it is transparent for most listeners.
About the OGG format
OGG Vorbis is a free, open lossy audio format that sounds better than MP3 at the same bitrate. It is common in games, on Wikipedia and in open-source software, and every desktop browser plays it, though Apple devices needed third-party apps for a long time.
Frequently asked questions
Why convert MP3 to OGG?
OGG Vorbis is free of patents and sounds better than MP3 at the same size. MP3 files are lossy and comparatively large for their quality; each re-encode loses a little more.
Does converting MP3 to OGG lose quality?
OGG uses lossy compression, so a little detail is discarded to make the file smaller. At 192 kbps or higher the difference is inaudible for most listeners; choose 320 kbps for the safest result.
Which bitrate should I choose?
192 kbps is transparent for most music and the default here. Use 320 kbps to archive or for critical listening, and 128 kbps for speech, where the difference is inaudible and the file is a third smaller.
Can I convert several MP3 files at once?
Yes. Add up to 5 files of up to 200 MB each, convert them in one go and download the results one by one or as a ZIP.
Are my files uploaded?
No. The conversion runs in your browser with ffmpeg compiled to WebAssembly. Your MP3 files never leave your device.
