Why Should You Compress MP3 Files?

There are many reasons as to why you should compress MP3 audio files: the main reason is, of course, to reduce the MP3 file size to save space in the hard disk or MP3 player. Another reason is to send the a MP3 song via email or messenger applications that limit the file size to be uploaded or shared, so reducing the MP3 file size will allow you to share the song easily. Our service can help you to reduce the file size of an MP3 song without compromising the audio quality, you can infact reduce the bitrate and thus the file size. For the best compromise between quality and low file size I would recommend to use the bitrate of 64kbps, anything below may reduce the audio quality.
