Why convert CAF to MP3?
MP3 files are typically 5-10x smaller than CAF, making them ideal for phones, sharing and streaming.
MP3 is best for music libraries, sharing, podcasts and playback on any device. Plays on virtually every phone, computer, car stereo, browser and media player.
Will I lose quality?
MP3 is a lossy format, so some inaudible detail is removed to save space. At 192 kbps or higher most listeners cannot tell the difference from the original CAF.
