About the Audio Converter

The audio converter turns a sound file into MP3 or WAV: an M4A from a phone recording, an OGG or Opus file from a chat app, a FLAC album track, or a WAV recording that is too large to share. It also makes WAV from MP3 for audio editors that need it.

Choose MP3 at 128, 192 or 320 kbps for a small file that plays everywhere, or WAV for sound that is not compressed again. The sample rate and the number of channels stay as they are (an MP3 holds up to 48 kHz and two channels, so more becomes 48 kHz stereo), and WAV keeps the bit depth of 24-bit and 32-bit float recordings.

The conversion runs in your browser. The file is not uploaded, so private recordings and unreleased music stay on your device.

How to use it

  1. Choose an audio file (MP3, WAV, M4A, AAC, OGG, Opus or FLAC), or drop it on the page.
  2. Check the length, format, sample rate and channels shown under the file name.
  3. Choose MP3 or WAV; for MP3, choose 128, 192 or 320 kbps.
  4. Press Convert and wait for the progress bar; you can cancel at any time.
  5. Listen to the result, then press Download.

Features

  • Common audio formats: Opens MP3, WAV, M4A, AAC, OGG, Opus and FLAC files that your browser can decode.
  • MP3 or WAV: MP3 at 128, 192 or 320 kbps, or WAV without another round of compression.
  • Same sound settings: WAV keeps the sample rate and channels of the original, and 24-bit and 32-bit float sound as it is. MP3 keeps them too, up to 48 kHz and two channels.
  • Size before you convert: See about how large the result will be for the format and quality you choose.
  • Private: Everything happens in your browser; nothing is uploaded and no account is needed.

Examples

Voice memo to MP3

Turn a 10-minute M4A voice memo into a 128 kbps MP3 of about 9 MB that any player opens.

FLAC for an old player

Convert a FLAC album track to a 320 kbps MP3 for a car stereo or an older music player.

WAV for an editor

Make a WAV from an MP3 so an audio editor or a video editor can open it.

Limitations and notes

  • Your browser must be able to decode the sound (WebCodecs): a recent Chrome or Edge, Safari 26 or later, or Firefox 130 or later. Older versions of Safari can still convert WAV files. Some formats, such as OGG in Safari, may not open.
  • MP3 is compressed: converting to MP3 loses a little quality, and converting an MP3 to MP3 again loses a little more. WAV made from an MP3 is larger but does not get its quality back.
  • Video files are not converted here; use Video to MP3 to save the sound of a video.
  • The sound of other formats is saved as 16-bit WAV; very long WAV files can be large, and the result is held in memory until you download it.

Frequently asked questions

How do I convert M4A to MP3?

Choose the M4A file, keep MP3 selected, pick a quality and press Convert. 192 kbps is a good choice for music.

Which MP3 quality should I choose?

128 kbps is fine for speech, 192 kbps for most music, and 320 kbps when you want the best MP3 quality.

Does converting to WAV improve the sound?

No. WAV keeps the sound exactly as it was decoded, but it cannot bring back what MP3 or AAC compression removed.

Why can my browser not open my file?

Some browsers cannot decode every format, for example OGG in Safari. Try a recent Chrome, Edge or Firefox.

Is my file uploaded?

No. The file is converted in your browser and saved straight to your device.
