An audio file converter is a type of file converter that (surprise!) is used to convert one type of audio file (such as an MP3, WAV, WMA, etc.) to another type of audio file. Below is my ranked list of the best free audio converter software programs and online converter services available. I routinely refresh this list as I come across new options and always only include freeware.

This is my top choice for three reasons: it works directly from their website, has no file size limitation, and supports batch conversion.

Apart from these things, Audio-Convert.com is similar to the other web-based converters below: add one or more files from your computer, Dropbox or URL and convert them to various formats online.

You can convert more than one file at a time and each file can have its own conversion settings or the same settings. This applies to format, encoder, quality, sample rate and channel.
