MP3 must be familiar to everyone, which is one of the most universal audio formats with high utilization rate and compatibility. As MP3 is already a lossy audio file saved in a compressed audio format, quite a lot of people wonder whether it's possible to further compress MP3 files. The short answer is YES! You can reduce MP3 file size by lowering the audio bitrate.
But you have to know that a higher audio bitrate generally determines better audio quality and brings high fidelity audio performance. Therefore, you will notice a significant drop in quality if you resize MP3 files to a much lower bitrate. Next, I'll elaborate on how to compress MP3 files free with six MP3 compressors in sequence.

If you only have a handful of MP3 files that need to be compressed, it's also a good option to reduce MP3 file size online. There are plenty of online audio compressors that offer a straightforward way to make MP3 file smaller without any software installation required. But on the flip side, most online services will bombard you with lots of ads, redirects and other potential risks. Based on my hands-on experience, the following 3 online MP3 size reducer are recommended.
MP3Smaller shows a brief and clean layout that allows you to reduce MP3 file size online without a hitch. What you need to do is just visit https://www.mp3smaller.com/, click "Browse" button to add an .mp3 file (max 150 MB), then select a smaller MP3 bitrate in the drop-down list. Finally, click "Upload File" button to start the uploading and compressing process. After done, you can click "Download File" link to save it to local drive. The biggest drawback is no batch MP3 compressing support, you can only select one MP3 file each time.
FreeConverter is an online service that offers audio, video, and even document conversions, including the free MP3 Compressor. You can directly open this link https://www.freeconvert.com/mp3-compressor, drag and drop your MP3 files to the dotted box area (Max file size 1GB). Then you're able to open "Advanced Options" window, where offers 3 compression methods: Target file size (percentage), Target file size (MB) and Target audio quality. Choose any option at will and apply the settings. Finally, hit "Compress Now!" button to batch resize MP3 files. When the process is complete, click "Download All" button to save a .zip package file contained compressed MP3s to your PC. Or you can choose to save it to Google Drive or Dropbox.
In addition to audio format conversion, Online Audio Converter can also work as an online MP3 compressor that provides a self-explanatory way to make MP3 file smaller. Visit this link: https://online-audio-converter.com/. Click on "Open files" button to add your multiple MP3 files, or add them from Google Drive, Dropbox or a URL. Select MP3 as export format. Next, you can drag the slider to determine the MP3 quality. You're also allowed to press "Advanced settings" button to choose a specific audio bitrate. When you're ready, hit the "Convert" button to upload and compress MP3 files online. When the process is finished, press the "Download" link to save your compressed MP3s, they'll be zipped in a package file, or save it to Google Drive or Dropbox.
Once again, MP3 compressing will inevitably make MP3 files smaller at the expense of compromising the sound quality. But as long as you don't set the audio bitrate too low, it's unlikely you'll be able to tell much difference.
As you see, with the 6 free MP3 compressors mentioned above, it's totally a cinch to compress MP3 files to smaller size. Hopefully, this post can shed some light on your matters. You can pick any option based on your need. Thanks for reading!
