About this tool

Convert voice messages, recordings, podcasts or songs to the format you need: MP3 plays everywhere, M4A (AAC) is small with great quality, WAV and FLAC keep every detail for editing, and OGG suits games and the web. You can also drop a video and keep only its sound. Choose the quality for MP3 and AAC: 128 kbps for small files, 192 kbps for everyday listening or 320 kbps for the best quality. Everything runs in your browser, so the file is never uploaded and works offline once the page has loaded.

How to use it

  1. 1 Choose or drop an audio or video file.
  2. 2 Pick the format: MP3, M4A, WAV, OGG, FLAC or AAC.
  3. 3 For MP3 and AAC, choose the quality (kbps).
  4. 4 Tap 'Convert and download'.

Frequently asked questions

Can I convert a WhatsApp voice message to MP3?

Yes. WhatsApp voice notes are OGG/Opus files; drop the file and choose MP3.

Which quality should I pick?

192 kbps sounds great for music and speech. Use 128 kbps to save space or 320 kbps for the best MP3.

Does converting improve the sound?

No. Converting to WAV or FLAC keeps what is there but cannot restore detail a compressed file has already lost.

Is the file uploaded?

No. The conversion happens entirely in your browser.
