We’ve rounded up the best audio converter programs for Windows. All of these apps are free and easy to use, so pick one that suits your needs and you’ll be converting your audio in no time.

MediaHuman’s Audio Converter program is one of the easiest tools to use due to its simple interface. It also works effortlessly, with support for many different quality audio formats. Above all, you can convert between lossless formats without degradation.

AVS Audio Converter allows you to convert your audio files to MP3, WAV, M4A, FLAC, etc. You can add files locally from your computer or CD, and even convert video to audio. Depending on the file format, customization options include channel, bit rate, and sample rate.

A handful of features are locked behind a $59 paywall, like multi-threaded conversion and merging multiple files into one, but if you just need a program to convert audio from one format to another, then AVS works wonders.

WinFF is not exclusively an audio conversion tool; it is also an excellent free video converter. But you can easily use it to convert your audio files to formats like MP3, OGG, WAV and WMA. It does not have a multitude of features, but it works perfectly.

WinFF uses the Windows command line to display the process of your conversion, which is why it’s not as sophisticated as some of the other tools we’ve mentioned.

Unfortunately, Freemake Audio Converter does not allow you to convert audio files longer than three minutes. If you want to do that, you have to pay for the Infinite package which costs $39.95, but don’t bother if you encounter the limitation, use another program from the list instead.
