Questions

What is inside an OGG file?
OGG is a container: the sound inside is usually Vorbis or Opus, sometimes FLAC. This tool reads all three and saves an MP3.
Can I convert voice notes from WhatsApp or Telegram?
Yes. They are OGG files with Opus sound — choose the file and it becomes an MP3. Voice notes ending in .opus work too.
Does the MP3 stay in stereo?
Yes — the MP3 keeps the channels of the original, up to two (stereo).
Are my files uploaded anywhere?
Your file never leaves your device. It is converted right here, in your browser — nothing is uploaded.
