Convert WAV to MP3
WAV is uncompressed, which is why it is enormous. MP3 is the format everything on earth can open, at roughly a seventh of the size.

Getting the converter ready — this happens once, then your browser keeps it.
The converter could not start.
The engine files are missing from — copy ffmpeg-core.js and ffmpeg-core.wasm there.
Almost always a mismatched build: the worker is an ES module, so the core has to be the esm one too. Copy ffmpeg-core.js and .wasm from @ffmpeg/core/dist/esm/, not dist/umd/.
not in this build of the converter, so it is not offered.
What you lose
This one does throw data away, and it does not come back. At 192 kbps the difference is inaudible on almost any speaker or headphone; at 128 kbps you may hear it on cymbals and applause. What you cannot do is convert back to WAV later and recover the original — that file will be WAV-sized again but not WAV-quality.
What you do not gain
Nothing about the recording improves. MP3 is smaller, more compatible and slightly worse, and those are the whole of the trade.
What it does to the size
Approximate, for stereo audio at the settings this tool uses by default. The real figure moves with the material — silence and speech compress far better than a full mix.
When this is the right conversion
Sending a recording to somebody, publishing it, or putting it on a phone. Keep the WAV if it is a master you will edit again.
