Quick guide

How to use Audio Format Converter

Audio Format Converter changes compatible audio files into common download formats without uploading them. Available outputs depend on the encoders supported by the current browser and device.

Steps

  1. Choose, drop, or paste an audio file that your browser can read.
  2. Select an available output format and its quality options.
  3. Convert the file locally, then download the new audio copy.

Good to know

  • MP3 and WAV are the most predictable outputs; AAC and Opus availability is checked at runtime.
  • Converting a lossy source again can reduce quality even at a high bitrate.
  • Input files are limited to 128 MB and never leave your device.
