Questions
Asked and answered
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.
320 kbps keeps the most, and from a lossless source it is the one case where the extra size buys something. 192 kbps is enough for most listening on earbuds or in a car, at 60% of the size of 320.
Yes. MP3 cannot hold more than 48 kHz, so the sound is resampled to fit. It is still taken from the full resolution file.
Title, artist, album and track number are copied into the MP3's ID3 tag. Embedded cover art is not.
Yes. Keep the FLAC as your master and make MP3s from it when you need them. Converting an MP3 back to FLAC does not bring the lost detail back.
