OGG to MP3

Convert OGG to MP3 online for free — turn OGG Vorbis and Opus audio, including WhatsApp and Telegram voice notes, into MP3 files that play everywhere. Choose 96 to 320 kbps, trim, fade and normalise quiet recordings. Runs privately in your browser.

100% private — your audio is converted on your device, never uploaded. Conversion happens on your device; nothing is uploaded.

100% private — runs in your browser

Your browser decodes the audio and an open-source MP3 encoder (LAME, via lamejs) converts it on your device — nothing is uploaded. Works with MP4, MOV, M4A, WebM, MKV, WAV, OGG and more; very long files need plenty of memory, so trim if your browser struggles.

How to convert OGG to MP3

  1. Drop your OGG (or .opus) file in the box.
  2. Choose the MP3 quality and stereo or mono.
  3. Optionally trim, fade or normalise.
  4. Click Convert to MP3, preview and download.

What you can use it for

  • Save WhatsApp and Telegram voice notes as MP3
  • Play game and app audio in any player
  • Use OGG sound effects in apps that need MP3
  • Share recordings with iPhone users

Frequently asked questions

Can I convert WhatsApp voice notes?

Yes — WhatsApp voice notes are OGG/Opus files. Save the voice note, drop it here and convert. Tick Normalise volume to make quiet notes clearer.

Does it work in Safari?

Recent Safari versions can decode OGG Opus and Vorbis; if a file won't open, try Chrome, Edge or Firefox.

Which quality should I choose?

192 kbps sounds excellent for music and keeps files small; 320 kbps is the highest MP3 quality. For podcasts and speech, 96–128 kbps in mono is plenty.

Can I convert just part of the file?

Yes — set a start and end time (minutes:seconds) before converting. Fade in and out smooths the cut edges.

Is there a file size limit?

There's no upload limit because nothing is uploaded, but the whole file is decoded in your browser's memory. Files up to a few hundred MB work well on most computers; for very long recordings, convert in parts.

Is my file uploaded?

No. Decoding and MP3 encoding both happen on your device.
