Having so many big size mp3 music files and wish to have a magic in making their file size smaller by preserving most of your mp3 file quality? This small software can help.
Known as MP3 Quality Modifier, users are now able to make their mp3 files smaller without losing out much on quality, retaining all ID3 tags with ease, and finally free of charge! Users can change attributes like bit rate, frequency of the mp3 files and make quality comparison with the original ones to reduce the bit rate in order to trim down the size dramatically.

Another great feature of this freeware is that it is an extremely small portable software with just one executable, no installation required to run.
