How to convert audio formats online

Format Converter changes an audio file from one format to another inside your browser. It is useful when a podcast editor, voice tool, music app, transcription service, or website requires a specific file type.

  1. Select an audio file such as MP3, WAV, M4A, OGG, FLAC, or AAC.
  2. Choose the output format that matches your target app or workflow.
  3. Select a bitrate when the format supports compressed output.
  4. Start conversion and keep the page open while your browser encodes the new file.
  5. Download the converted file and test it in the target application.

Format Converter FAQ

Which format should I choose?

MP3 is broadly compatible, WAV is best for editing, FLAC is lossless when supported, and OGG/M4A/AAC are useful for smaller web or mobile files.

What does bitrate change?

Bitrate controls the balance between quality and file size for compressed formats. Higher bitrate usually sounds better but creates a larger file.

Why are some formats unavailable?

Advanced formats depend on browser codec support and WebAssembly encoders. If a format is unavailable, try Chrome, Edge, or Firefox.

Is the original file modified?

No. The original file stays on your device unchanged. The converter creates a new downloadable output file.
