How to Reduce MP3 File Size
MP3 files are a file format meant for audio storage. While they are generally smaller than WAV files, which also are meant to store audio, they can still be too big to meet a certain size requirement. Compressing or finding ways of shrinking an MP3 file is a fairly simple process, but your results won't be drastic. Since MP3s are already compressed, the changes may be negligible.
Things You'll Need
- Finder on a Mac
- WinZip on a PC
On a Mac
Open a Finder window, and navigate to the folder where your MP3 is located.
Right-click on the MP3 file name.
Select "Compress Name-of-file.mp3." A compressed copy of your file will appear in your Finder window.
On a PC
Download WinZip or other file-compression program. You will eventually have to pay for the program, but it offers a free trial.
Install and open WinZip.
Choose the Wizard from the mail toolbar.
Select "Create a new zip file" from the options.
Name your file.
Add your MP3 files to WinZip when prompted.
Click on the "Zip Now" button.
When Importing Music
If you wish to create smaller MP3s when importing files from a CD, navigate to "iTunes," then "Preferences." Choose the "Import Settings" tab.
Choose "Custom" as the setting, and "MP3 Encoder" as what to use to import. This should make the MP3 encoder window come up.
Choose "Use Variable Bit Rate Encoding (VBR)," and choose "Medium" or lower.
Lower the sample rate, or switch it to "Auto" on its drop-down menu.
Change the channel from "Stereo" to "Mono." This will decrease the file size, but also cause your audio to sound more flat. Use it just as a means to drop down your file size.
Select "OK," and import your music.
