MP3
Max file size: 100 MiB
Choose a Vorbis quality
Pick quality 2 to 9, nominally about 96 to 320 kbps. Vorbis varies the bitrate with the sound, so quiet or simple passages take less space.
Whole recordings up to 30 minutes
Convert a complete MP3 of up to 30 minutes in one go, or enter a start time and duration to save just a section.
Keeps the channels and sample rate
Mono stays mono, stereo stays stereo and a 44.1 kHz song stays 44.1 kHz. The length of the OGG is checked against the MP3 before you download it.

Frequently Asked Questions
Does converting MP3 to OGG improve the sound?
No. MP3 is already compressed, and Vorbis compresses the decoded sound again, so a little more detail can be lost. Choose quality 6 or higher to keep the difference hard to hear, or keep the MP3 if the program you use accepts it.
Which quality should I choose?
Quality 5, nominally about 160 kbps, suits most music, and quality 2 or 4 is enough for speech. Vorbis varies the bitrate with the sound, so the actual average can be lower or higher than the nominal figure. A setting far above the MP3's own bitrate only makes the file larger.
Will the OGG file play on my device?
Ogg Vorbis plays in Chrome, Firefox and Edge, in VLC, on most Android phones and in game engines such as Godot and Unity. Some Apple apps, including Music and QuickTime Player, do not open Ogg files; keep an MP3 or M4A copy for those.
What are the limits?
Upload an MP3 of up to 100 MiB and 30 minutes. The whole recording can be converted in one export, and the OGG can be up to 80 MiB. Variable-bitrate MP3s without a length header are measured frame by frame, so their full length is converted.
Are tags and cover art kept?
No. Title, artist and album tags, embedded artwork and chapters are not copied to the OGG. Add tags again in your music library or audio editor if you need them.
Where are files processed and when are they removed?
This tool uploads files to Zutilium's server for processing. After a successful conversion, uploads are scheduled for deletion after about one minute and generated downloads after about ten minutes. Cleanup runs periodically, so removal is not immediate. Save your result promptly.
