10 Free Audio Converter Software Programs

Best Free Audio Converters for MP3, WAV, OGG, WMA, M4A, FLAC and More!

An audio file converter is one kind of file converter that (surprise!) is used to convert one type of audio file (like an MP3, WAV, WMA, etc.) into another type of audio file.

If you're unable to play or edit a certain audio file the way you wanted because the format isn't supported by the software you're using, one of these free audio converter software programs or online tools can help.

Audio file converter tools are also helpful if your favorite music app on your phone or tablet doesn't support the format that a new song you downloaded is in. An audio converter can convert that obscure format into a format that your app supports.

Below is a ranked list of the best free audio converter software programs and online converter services available today:

Important: Every audio converter program below is freeware. I haven't listed any shareware or trialware audio converters. Please let me know if one of them has started charging and I'll remove it.

SUPER is very much a superior free audio converter. The best thing about SUPER is the long list of audio formats it supports.

If you have a rare audio file you want to convert to something more common (or vice versa), you should try the SUPER audio converter.

Input Formats: AAC, AC3, AMR, APE, FLAC, MMF, M4A, MP2, MP3, MPC, MPP, OGG, RA, RAM, RM, TTA, WV, WAV, and WMA

Output Formats: AAC, AC3, AMR, APE, FLAC, MMF, MP2, MP3, MPC, OGG, TTA, WV, WAV, and WMA

You can also extract the audio from most common video formats with SUPER and save as any of the above Output Formats.

Important: During installation, be sure to quit/close the "InstallPath Install Manager" window. After it closes, you'll still be able to complete the SUPER install.

Also, bear in mind that some toolbars or other programs may install silently along with SUPER. There is an alternative download link on their download page that doesn't include such additional programs but it's not as easy to download.

Download SUPER for Free

SUPER can seem intimidating but it's only because the program shows several advanced options by default. The SUPER audio converter is actually really easy to use.

It's said that SUPER will work with most versions of Windows. I used SUPER in Windows 10 without any issues. More »

FileZigZag Review and Link

The worst thing about FileZigZag is the time it takes to upload the audio file and receive the link in your email. But most audio files, even long music tracks, come in a pretty small size so it's not usually a problem.

Zamzar Review and Link

The biggest disadvantage with Zamzar is their 50 MB limit for source files. While many audio files are smaller than this, some low compression formats can exceed this small limit.

I also found Zamzar's conversion time slow when compared to other online audio converter services.

Zamzar can be used with pretty much any modern web browser on any OS, such as Windows, Mac, and Linux. More »
