HOW IT WORKS 02
Pick your files,
save just the result.
Choose the quality
Standard suits speech; high quality or above is recommended for music.
Save the MP3
The video track is dropped and only the audio is saved as MP3.
Why save as MP3?
MP3 plays on almost every device, car stereo and player. It is much smaller than the video file, so it is easier to keep or send in a messenger.

Standard is enough for speech-heavy content like lectures and meetings. High quality or above is recommended for music, and setting it higher than the source does not make the sound any better.
