DietMP3 can significantly reduce (by 30 to 70 percent) the size of an original MP3 file with very minor loss in quality. Rip or grab CD tracks directly to “dieted” MP3 files. These small files allow you to put more songs onto your portable MP3 players without an expensive flash memory upgrade. If you prefer to burn onto a mini CD-R or CD-RW, DietMP3 can help you to place 30 to 70 percent more songs on a disc.
