Does converting to WAV improve the audio quality?

No — WAV is lossless, but it cannot restore detail a lossy source (like MP3) already discarded. It just re-encodes the decoded audio without further compression.

Why is the WAV file much larger than my original MP3?

WAV stores uncompressed 16-bit PCM samples, while MP3 is compressed — a 3-4 MB MP3 can easily become a 30-40 MB WAV.

Does this tool upload my audio anywhere?

No — decoding and encoding both happen locally in your browser.
