OGG to MP3 for voice messages

A voice note saved from Telegram or WhatsApp is an .ogg or .opus file that many players won’t open. Make it an MP3 that plays anywhere. Private messages stay with you: we never receive the file or store it.

OGG files only · other formats open in “Audio converter”

How it works

  1. Save the voice noteTelegram Desktop: right-click → Save As. WhatsApp: export the chat with media, or take the .opus file from the phone.
  2. Open it here.ogg, .oga and .opus all work. A one-voice note gets 64 kbps mono, music 192 kbps.
  3. Save the MP3A minute of speech comes out at about 0.5 MB.

What sits inside an .ogg voice note

OGG is a wrapper, and the sound inside is usually Opus, a codec built for voice over the internet. Telegram, WhatsApp and Discord record voice messages with it because a minute of speech fits into about 250 KB. Outside the app, though, plenty of players, car stereos, office PCs and transcription services don’t know it. Turning OGG to MP3 takes care of that.

Where these files come from

  • Telegram saves voice messages as .ogg or .oga.
  • WhatsApp on Android keeps them as .opus in its Voice Notes folder; an exported chat has them as .opus too.
  • Older games, Linux music players and some radio recordings use OGG Vorbis. It opens here as well.

Quality picked from the file

  • A mono file, and every voice note is mono, gets a 64 kbps mono MP3. Speech stays clear.
  • A stereo OGG, usually music, gets Good, 192 kbps.
  • Measured: a 23-second Opus note of 91 KB became a 182 KB MP3. Twice the size, the same voice.

Why the MP3 is bigger

Opus is about twice as efficient as MP3 for speech. To keep a voice equally clear, the MP3 needs more bits, so the file grows. It doesn’t sound better, it just opens in more places.

Browsers and phones

  • Chrome, Edge and Firefox open Opus and Vorbis.
  • Safari reads Opus from version 26. An older Safari may refuse the file, and the page says so before you start.
  • On Android, open the page in Chrome and pick the file from Downloads or the WhatsApp folder.

What people do with the MP3

  • Send a voice note to someone who doesn’t use the app, or attach it to an email.
  • Upload it to a transcription service that wants MP3.
  • Keep an important message in a format any player opens years from now.
