MP3 Quality Modifier enables you to easily change the quality of your mp3 files to reduce the file size while maintaining the desired level of audio quality. The program achieves this primarily by adjusting the bitrate based on the selected quality profile or custom settings. Advanced users can also adjust the stereo settings and change the Sample Frequencies for additional control over the output resuls. You can process individual files or entire folders and view a before/after size comparison when the process is finished. MP3 Quality Modifier is designed to reduce file sizes of your MP3 files in order save disk space and/or to fit more music on your portable device without sacrificing sound quality. Standalone software, no installation required.

The main purpose is to change the bitrate of your mp3 music collection in a really simple but intuitive way so that the filesize can be dramatically reduced while the audio quality stays the same. With this advantage it's possible to put more music on your mp3-player or just to save some disk space.
Even advanced tasks are possible: Downsampling, changing the used channels and so on. With the included presets it's simpler than ever before to manage all the provided settings.
Helpful for the concluding quality comparison is the generated summary that comes after a process because it truly points out the made change by illustrating the filesize modification.
