Worked example
Measured on our own 17 second voice note in Ogg Opus, saved as MP3 at 64 kbps.

Opus is built for voice at low bitrates, so the MP3 needs twice the space to hold the same speech. For a voice note, 64 kbps is plenty; the default 128 kbps doubles it again.

No. The file is read by the page and converted by ffmpeg compiled to WebAssembly, on your own machine. There is no upload step, and closing the tab discards everything.
Save or share the voice note to your phone or computer first. It comes out as an .opus or .ogg file. Drop it here, keep MP3, and convert. A voice note is mono, so the MP3 stays mono and small.
Not for converting. Both decode the same way here. It only matters for how small the original was: Opus is built for speech at low bitrates, which is why voice notes use it, and Vorbis is older and common in games and media players.
Slightly, in theory, because the sound is compressed a second time. Pick a bitrate well above the source, 64 or 128 kbps for a voice note and 192 for music, and the difference is very hard to hear.
Yes, with the audio converter: drop in the MP3 and pick OGG, which writes Vorbis audio, as the output.
