What is converting a file to WAV?

Tips for converting to WAV

What this converter writes, and which files it leaves alone.
  • 01

    Expect a larger file

    WAV stores uncompressed samples, so the download is often larger than an MP3 or M4A.

  • 02

    Video files

    A video such as MP4 uses the MP4 to WAV converter. This page reads audio files.

  • 03

    Already a WAV

    A file that is already .wav does not need this conversion.

Good uses for a WAV converter

When an editor or player wants uncompressed audio.

  1. Edit a compressed file: Turn an MP3 or M4A into a WAV an audio editor can open.

  2. Keep the sample rate: The WAV uses the rate already stored in the source file.

  3. Share a standard wave file: A 16-bit WAV is the wave format most players accept.
