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 want 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.

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

Input Formats: 3GA, AAC, AC3, AMR, AMV, APE, ASFAVI, AVS, CMF, CPT, DAT, DTS, DV, DVR-MS, FLAC, FLC, FLV, GXF, IFO, M4A, M4V, MPR, MTS, M2TS, MKV, MMF, MOV, MP2, MP3, MP4, MPC, MPP, MPG, MTV, MXF, MXG, NSV, OGG, OGM, OFR, QT, RA, SHN, STR, SWF, TAK, TS, TRP, TTA, VIV, VQF, VOB, WAV, WEBM, WMA, WTV, and WV

Output Formats: AAC, AC3, AMR, APE, DTS, FLAC, MMF, M4A, MP2, MP3, MPC, OGG, RA, SHN, TAK, TTA, WV, WAV, and WMA

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 might 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 it in Windows 10 without any issues. More »

Freemake Audio Converter supports several common audio formats and is extremely easy to use. However, it only supports audio files that are shorter than three minutes.

In addition to converting single audio files into other formats in bulk, you can join multiple files into one larger audio files with Freemake Audio Converter. You can also adjust the output quality before converting files.

The biggest drawback to this program is that have to buy the Infinite Pack to convert audio files that are longer than three minutes.

Input Formats: AAC, AMR, AC3, FLAC, M4A, M4R, MP3, OGG, WAV, and WMA

Output Formats: AAC, FLAC, M4A, MP3, OGG, WAV, and WMA

Download Freemake Audio Converter For Free

Note: The installer for Freemake Audio Converter will attempt to install another program that's unrelated to the converter, so be sure to uncheck that option before finishing setup if you don't want it added to your computer.

You might also want to check out Freemake Video Converter, another program from the same developers as Freemake Audio Converter that supports audio formats too. It even lets you convert local and online videos into other formats. However, while Freemake Audio Converter does support MP3s, their video software does not (unless you pay for it).

Freemake Audio Converter can for sure run on Windows 10, 8, and 7, and is likely to work with older versions too.  More »

You can upload remote audio files via their direct URL as well as files stored in your Google Drive account.

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. However, most audio files, even long music tracks, come in a pretty small size, so it's not usually a problem.

FileZigZag should work with all operating systems that support a web browser, like macOS, Windows, and Linux. More »

Zamzar is another online audio converter service that supports most common music and audio formats.

Upload the file from your computer or enter a URL to an online file that you need converted.

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 »

Another free audio converter is called Switch (previously Switch Sound File Converter). It supports batch conversions and whole folder imports, as well as drag and drop and lots of advanced settings.

You can also use Switch to extract audio from your video files and CDs/DVDs, as well as capture audio from a live audio stream from the internet.

Input Formats: 3GP, AAC, ACT, AIF, AIFC, AIFF, AMR, ASF, AU, CAF, CDA, DART, DCT, DS2, DSS, DV, DVF, FLAC, FLV, GSM, M4A, M4R, MID, MKV, MOD, MOV, MP2 ,MP3, MPC, MPEG, MPG, MPGA, MSV, OGA, OGG, QCP, RA, RAM, RAW, RCD, REC, RM, RMJ, SHN, SMF, SWF, VOC, VOX, WAV, WMA, and WMV

Output Formats: AAC, AC3, AIF, AIFC, AIFF, AMR, APE, AU, CAF, CDA, FLAC, GSM, M3U, M4A, M4R, MOV, MP3, MPC, OGG, OPUS, PLS, RAW, RSS, SPX, TXT, VOX, WAV, WMA, and WPL

Download Switch for Free

Note: Make sure to use the download link in the "Get it Free" section (here's a direct link if you don't see it). 

Some of the advanced settings in Switch include deleting the source audio file after a conversion, automatically normalizing audio, editing tags, and downloading CD album details from the internet.

Another option worth noting is one that lets you set up to three preset conversion formats so that you can right-click on an audio file and choose one of those formats for a quick conversion. It's a huge time saver.

macOS (10.5 and above) and Windows (XP and newer) users can install Switch.

Important:

Some users have reported that the program stops letting you convert files after 14 days. I haven't experienced this but keep it in mind, and use a different tool from this list if you run into that.

If that happens to you, something you might try is starting the uninstall process and seeing if Switch asks you to revert to the free, non-trial version (instead of removing the program).

Some users have also reported that their antivirus software identifies Switch as a malicious program, but I haven't seen any messages like that myself.

If you're having troubles with Switch, I highly recommend using a different program from this list. The only reason it remains here is because it works perfectly fine for some people. More »
