Some software will only take a WAV. Old editors, some DAWs, a lot of hardware samplers, and most speech tools want uncompressed audio, and hand back an error rather than a decoded MP3.
This decodes the MP3 and writes the samples out as 16-bit PCM, which is what a WAV means to everything that reads one. There are no settings, because there is nothing to decide — the samples are what they are.
What it will not do is undo the compression. An MP3 has already thrown detail away permanently, and a WAV made from one is a faithful uncompressed copy of the compressed audio, roughly ten times larger with not one bit more quality. That is the honest reason to do it: compatibility, not restoration.

Questions
Does converting to WAV improve the quality?
No. The detail an MP3 discarded is gone. The WAV is a larger, uncompressed copy of exactly what the MP3 contains.
Why is the file so much bigger?
WAV stores every sample uncompressed — about 10 MB a minute in stereo. That is the format doing its job.
What bit depth do I get?
16-bit PCM at the file’s own sample rate, which is what almost everything expects from a WAV.
