FORMAT QUESTIONS
About MP3 files
What is MP3 best used for?
MP3 works especially well for music, speech, and portable playback.
What can change during conversion?
It is lossy, so converting from another lossy format cannot restore quality. Features that do not exist in the chosen output format cannot be carried across exactly.
Should I keep the original MP3 file?
Yes. Keep the original until you have opened the result and checked its layout, quality, data, media tracks, or other important details.
