FLAC is compression that throws nothing away. Decode a FLAC and you get back the exact samples that went in, bit for bit, at roughly half to two-thirds of the WAV’s size. For anything being archived rather than listened to on a phone, there is no argument for keeping the WAV.
That makes this the one conversion here with no trade-off to explain. There is no quality setting because there is no quality decision: the output is the input, smaller. The only thing you give up is that a few old players cannot read FLAC, and those same players are the reason the MP3 pages exist.
The encoder is libFLAC compiled to WebAssembly, fetched when this page needs it, and it runs on your machine. A folder of session recordings compresses one file after another without any of them leaving the tab.

Questions
Is anything lost?
No. FLAC is lossless: decoding gives back the identical samples. It is the same audio in less space.
How much smaller is it?
Usually 40–60% of the WAV, depending on the material. Quiet or simple recordings compress most; dense loud ones least.
Should I use FLAC or MP3?
FLAC to keep, MP3 to carry. FLAC is the archive; MP3 is the copy you put on a phone.
