What the tool does, how to run it, and what to expect from the result.
WMA is Windows Media Audio, common in old Windows Media Player rips and recorders; Macs, iPhones and most phones do not play it. MP3 is the compressed audio format every phone, car stereo and player supports. The conversion runs in your browser with ffmpeg compiled to WebAssembly, so the file never leaves your device and there is no size limit beyond your memory. Both formats are compressed, so pick a bitrate at least as high as the source to avoid audible loss.

Both formats are compressed, so pick a bitrate at least as high as the source to avoid audible loss.
