MP3 to OGG: common questions

Is this MP3 to OGG converter free?
Yes. Files up to 500 MB convert free, without an account and without a watermark. Pro raises the limit to 2 GB a file and converts up to 30 files at a time.
Why do games use OGG instead of MP3?
OGG Vorbis is free of licensing terms and loops without the short silence MP3 adds at the start, which matters for background music. Godot imports it directly, and Unity accepts it too.
Is OGG better quality than MP3?
At the same bitrate Vorbis usually sounds a little better. Converting from MP3 can't improve on the MP3, though, so convert from the original WAV or FLAC when you have it.
Is my audio uploaded?
No. The conversion runs in your browser, so the audio stays on your device and never reaches our server. Once the page has loaded it keeps working if your connection drops.
Why does the first conversion take a few seconds to start?
The converter is a copy of FFmpeg that runs in your browser. It's about 31 MB, so it downloads the first time you use it and your browser keeps it for next time.
