Convert OGG and Opus Voice Notes to MP3

WhatsApp and Telegram voice messages, Discord recordings and many Linux apps save audio as OGG with Opus or Vorbis inside. iPhones, car stereos and plenty of upload forms won't play them. Convert to MP3 here and it plays anywhere, without the message ever leaving your device.

Your file never leaves your device. Nothing is uploaded.

How it works

  1. Pick a file. Drag in a recording, a voice memo or a video. It opens in this tab; nothing is sent to a server.
  2. Choose the format. MP3 or M4A for small files that play anywhere, WAV or FLAC when you need lossless audio, OGG for the web. Set the quality if you like.
  3. Download it. Your browser converts the file and saves the result to your device. If you need a transcript, send the new file to the free Wave AI transcription tool in one click.

Common questions

Which bitrate for OGG voice notes?

Voice notes are recorded at a low bitrate (often 16 to 32 kbps Opus), so 128 kbps MP3 already keeps every detail. Higher settings just make the file bigger.

Is my voice message uploaded?

Nowhere. The converter runs inside your browser tab, so the file is read and converted on your own device and saved straight back to it. It is never uploaded to Wave or anyone else, and we never see its name or contents.

Can I convert many voice notes at once?

One at a time for now. Each voice note takes a second or two once the converter has loaded, and the converter stays loaded while the tab is open.

Can I transcribe a WhatsApp voice note?

Yes. Convert it to MP3, then click "Transcribe this file for free" to get the text in the free Wave AI transcription tool, in any of 15 languages.
