Why Convert to a Different Audio Format?

Sometimes it’s necessary to convert a music file into another audio format for compatibility reasons. You may find for example that the new portable device you've just purchased cannot play your favorite tracks. This might be because they are encoded in a less popular format and therefore one that your device doesn't support.

Another reason why you might want to convert to a different format is if you store your original music library in a lossless format. File sizes are often much larger and not that well suited to store on portable devices like smartphones. So, in this case you'll want to convert to a lossy format like MP3 before syncing..

This guide lists some of the best free software for converting between audio formats. They have been selected due to their good audio format support and ease of use -- not to mention being free too!

Free MP3 WMA Converter has a user-friendly interface and has excellent audio format support. It can handle MP3, WMA, OGG, APE, FLAC, MPC, and WAV.

Once you have added all your files to the program's batch list, it's relatively straightforward to pick an output format via a drop-down menu.

As a bonus, there’s also a built-in tag editor which can be used to edit basic ID3 information. This could be useful if you need to change metadata before converting.

The installer comes with some potentially unwanted software, so be sure to un-check / decline the various offers if you don't want this also  installed on your system.

Overall, Free MP3 WMA Converter is a great ‘no frills’ tool that does a great job of converting between popular audio formats. More »
