Audio Format Converter processes files locally in your browser.

Convert audio files online

Convert supported audio files into MP3, WAV, or FLAC without installing software. Choose a file, select an output format, convert it in your browser, and download the finished audio file.

Your audio is processed locally on your device and is not uploaded to Looty Tools.

How to convert an audio file

  1. Choose a supported audio file.
  2. Select MP3, WAV, or FLAC as the output format.
  3. Select Convert to .mp3, Convert to .wav, or Convert to .flac for your chosen format.
  4. Wait while the audio is processed in your browser.
  5. Download the converted file.

Supported audio formats

Input formats: MP3, WAV, FLAC, M4A, AAC, and OGG.

Output formats: MP3, WAV, and FLAC.

  • MP3 creates smaller files with broad compatibility.
  • WAV is uncompressed and usually produces larger files.
  • FLAC uses lossless compression and is usually smaller than WAV.

Changing a file format does not restore audio quality already lost in the source recording.

Private browser-based audio conversion

Audio conversion runs locally in your browser using the bundled FFmpeg conversion engine. Your file is not uploaded to Looty Tools, stored on our servers, or sent to an external conversion service.
