Keep the sound quality, recompress MP3 files, and let your MP3 player hold more songs.

MP3 is a compression format that can compress music files while maintaining sound quality close to that of CDs, and it is widely used in computers and various home audio products.

But did you know? Even though MP3 music files are already much smaller than the original uncompressed files, they still have the potential to be further compressed with the use of DietMP3 software!
