Questions
Good to know.
Is my file uploaded?
No. It is converted in this tab with your browser, so the file never leaves your computer.
What is a MP3 file?
MP3 is compressed sound that plays on almost every phone, car stereo, player and website.
Why convert to OGG?
OGG is an open format that usually holds Vorbis or Opus sound. It is common in games and on Linux, but Apple's Music app does not open it.
Does it lower the quality?
The sound is re-encoded as Opus, which sounds very good at small sizes, but any re-encode loses a little.
Vorbis or Opus?
The OGG files made here hold Opus sound, which browsers and most game engines play. A few old players only know OGG Vorbis.
Is there a size limit?
The file is handled in your browser's memory, so very large files can fail. Close other tabs and try again.
Which browsers work?
Current Chrome, Edge and Firefox can make OGG files. Safari may not be able to encode the sound.
