Update: The conversion tool used for this tutorial was recently updated, so this guide now works fine for Mac OS 10.4 Tiger / 10.5 Leopard / 10.6 Snow Leopard.
Windows users who have switched to Mac often need to convert their WMA files (as it cannot be used in an iPod or played on iTunes on the Mac easily). There are many paid software to convert WMA files to MP3 (like Switch Pro and Easy WMA), while the precious few free and excellent WMA – MP3 converters are not written about or promoted.
In this tutorial, we will use only a free software, called All2MP3, to convert WMA files to MP3. It works on Mac OS X 10.3 and above. We have already used All2MP3 in our tutorial on converting .flac to .mp3 – it converts most common audio formats like FLAC, OGG, .wma, WAV and AIFF to MP3.
Convert WMA files to MP3
Follow the steps below to convert WMA files to MP3 using an easy drag-drop software called All2MP3.ADVERTISEMENT
Download All 2 MP3
Install All 2 MP3
Double-click the All 2 MP3 zip file to get a .mpkg installer file. Unlike many other applications, you cannot just drag-drop the app to Applications folder to install it.
Double click it to begin the installation. You will have to click continue a couple of times, then click “Agree”.
Then click “Install” and enter your Mac OS X login password. Once setup is done, you will be presented with a confirmation.
.wma to .mp3 conversion
Double click the All 2 MP3 icon from Applications to start it. Drag and drop your WMA files (it can convert multiple files at once) to the All 2 MP3 window.
Settings for .wma conversion
Choose bit rate for your song – depending on the quality you require (indicated as high/medium/low), and also the original file bit rate. If your original file is, say, 256 Kbps, do not select a higher bit rate than that.
Hit All2MP3 button to begin the conversion. Once conversion is done, a confirmation will be shown. The converted .mp3 files will be in the same location as the original .wma files.
What is .wma ?
Windows Media Audio, commonly called WMA, is a proprietary audio compression format by Microsoft. WMA consists of four codecs: WMA codec, and variants like WMA Pro, WMA Lossless (similar to FLAC).
Although WMA files can be played on Mac OS X using plugins for Quicktime, it is often a hassle, and even part-time OS X users should consider converting them to a better-supported format like MP3. For conversion, there are paid tools like Switch Pro and EasyWMA, but we figured, most users would be looking for free tools. Hence, the need for this tutorial.
