Convert audio files to MP3, WAV or OGG

Choose an audio file, pick the format you need and download it. Convert a WAV to MP3 to save space, an M4A or voice note to MP3 so any phone can play it, or an MP3 to WAV when editing software or a form asks for uncompressed audio. It all runs in your browser, so your recordings never go to a server.

Which format to choose

Format Best for File size
MP3 Sharing, playing on any phone, car or laptop Small
WAV Editing, transcription services, forms that ask for WAV Large (uncompressed)
OGG Web and open-source apps Small, but not every phone plays it

Common conversions

  • WAV → MP3: shrink a recording to share it.
  • M4A (iPhone voice memos) → MP3.
  • WhatsApp voice note (.opus / .ogg) → MP3.
  • MP3 → WAV for an editor.

Tips

  • Convert only once. Each MP3 or OGG conversion loses a little quality.
  • Need only part of the file? Cut it first.

Limits

Protected (DRM) files and some rare codecs can’t be converted, and the page tells you so. The first run downloads the converter once.

Record a new clip with the voice recorder, or pull the sound out of a video with MP4 to MP3.

Frequently asked questions

How do I convert WAV to MP3?

Choose the WAV file, pick MP3 and convert. The MP3 is much smaller and plays on almost every device.

Can I convert M4A or a WhatsApp voice note to MP3?

Usually, yes. Save the file to your device and choose it here. If its codec is not supported in the browser, the page shows an error instead of a broken file.

Which format should I pick?

MP3 for sharing and playing anywhere. WAV when an editor or a form asks for uncompressed audio. OGG for a smaller open format, though some phones don’t play it.

Can I convert a video’s sound?

Yes. Choose the video and the picture is ignored. For MP4 to MP3, the Extract audio from video page is the quickest.

Is my audio uploaded?

No. Conversion runs in your browser with ffmpeg.wasm.
