Converting audio is usually a case of changing format, for example WAV to MP3, FLAC to AAC or an old WMA to something modern, and the best free tools do it in bulk without limits. fre:ac is a GPL-2.0 desktop converter and CD ripper that handles all the usual formats and is free without a catch. MediaHuman Audio Converter is a friendly freeware app for Windows, macOS and Linux with drag-and-drop batches, though a feature for renaming files is sold separately. FFmpeg is the engine behind many converters; it is free and extremely capable but works from the command line. VLC, the media player, also has a convert option, which is convenient if you already have it. Audacity can import and export common formats and is the right choice if you need to edit before saving. If you do not want to install anything, CloudConvert works in the browser, but the free tier is limited to 10 conversions a day with a 5-minute processing cap on each. Choose desktop tools for large libraries and any privacy-sensitive files, since uploading sends your audio to a server. Remember that lossy to lossy conversion, such as MP3 to AAC, reduces quality every time, so keep an original or lossless master whenever you can.
