Free: AC Audio Converter is a full-featured tool that converts music files to several formats. Currently, the program supports MP3, AAC, MP4/M4A, FLAC, Ogg Vorbis, and Bonk formats.

If you want to batch-convert audio files, add them to a job list and then select an encoder to convert. If you need to rip a CD, this free tool is ideal because it converts your music to one of the above formats. It's also smart enough to add ID3 tag information automatically through the Compact Disc Database (CDDB).

If you’re looking for a combined CD ripper and file-format converter, then this might be the only tool you'll need.

Available as a free download for Windows, macOS, and Linux.

Overall, Free MP3 WMA Converter is a no-frills tool that does a great job of converting between popular audio formats. It's available as a free download for Windows or macOS.

Switch Audio File Converter

What We Like

  • Simple to use.

  • Batch file conversion.

  • Supports over 40 file formats.

  • Free version available.

What We Don't Like

  • Basic user interface.

  • Free trial supports limited file formats.

Available as a free download for Macs and PCs, the free version of Switch Audio File Converter converts MP3, WMA, AC3, AIFF, AU, WAV, and VOX formats.

When you first install the program, you'll get a taste of what the full version (Switch Audio File Converter Plus) can do. After a while, this reverts to a free version (for non-commercial home use only) that doesn't expire.

The clean, simple interface makes converting files quick and easy. And it also comes with a basic player to listen to tracks. However, the free version doesn't support lossless formats like FLAC unless you upgrade. But, if all you want to do is convert to MP3, for example, then it is still a useful tool.
