Fast
Audio is light work on most devices: most files are processed in just a few seconds, with a progress bar for the longer ones.
Clean sound
A high-quality encoder (LAME for MP3, AAC, Vorbis, Opus, FLAC) at the bitrate you choose. Lossless formats stay lossless.
Simple options
MP3 Speed asks only for what really matters and uses sensible defaults, so the first result is usually the right one.
