This is one of those apps you have to be careful with because the installer tries to throw some third-party software on your machine (details at the end of the post), but the end result is worth it. The Free MP3 WMA Converter from Koyote is capable of converting your entire audio library from one format to another.

The interface is very simple as you can see in the screenshot below. All you have to do is drag and drop music files from Windows Explorer into the “files to convert” area, select your output format, and click the Convert button. It really is that easy. How fast is it? I tested it with a few different songs and converted them to various different formats. I never had a conversion take longer than 20 seconds for a single song. That means it can process at least 180 songs per hour.

I’m sure the big question is what formats does it support? Here’s a list of filetypes that can be inputted, and then what formats they can be converted to:

  • Input formats: MP3, WAV, WMA, Ogg, AAC, APE, Flac, M4A, AC3
  • Output formats: MP3, WAV, WMA, AAC, APE, FLAC

Overall my experience with this app was really good once I got past the installation. It was simple enough to use that I think anyone would be able to figure it out in no time at all, and it processed the audio files at a reasonable pace.

IMPORTANT: During the install there are TWO checkboxes you’ll want to remove otherwise it will change your search engine and also install a toolbar. It will also try to install a 30-day trial of “Easy Mp3 Wma Cutter” and a “Free CD Ripper” app at the end of the installer. Just don’t click through too fast and you should be fine.
