About this tool
FLAC is WAV without the waste: the same bit-perfect audio at roughly half the size, with proper support for tags and cover art. It is the format for archiving masters, CD rips, and field recordings that you want to keep forever without losing a single sample.
About the formats: WAV stores uncompressed PCM audio: perfect quality, but around 10 MB per minute. It is the format audio editors, samplers, and studios expect. FLAC is lossless compressed audio: identical to the CD or master, at roughly half the size of WAV. Great for archiving, awkward for phones, car stereos, and streaming uploads.

Questions
Is WAV to FLAC really lossless?
Yes. FLAC compresses like a ZIP file: decoding it gives back exactly the original samples.
How much smaller will the FLAC be?
Typically 40-60% smaller than the WAV, depending on how complex the audio is. Silence and simple tones compress far more.
