How To Compress Large mp3 Files Quickly: 3 Methods Offered

If you handle audio content daily, such as podcasts or music, audio file compression would be a staple need for you. Size can be a hurdle sometimes, as many platform limit file size to upload and you might be stuck with a storage budget as well.

However, you might have concerns as compression might lower the file’s quality. There are tricks to avoid it, such as multiple compressions or ratio and attack adjustment.

There are a handful of easy and effective ways to reduce audio file size easily. Here we list three simple methods to make mp3 files smaller.

Part 1: Lossless compression VS lossy compression

There are two different compression modes known to audio professionals. These are lossless compression and lossy compression.

Lossless compression is best for long-term storage as it preserves the original data and enables you to have a high-quality result that you can remix in the future. However, as it keeps all the original data intact, the compressed output file will remain considerably big.

Meanwhile, for short-term use and everyday usage, such as social media, you can opt for lossy compression to reduce audio file size. This format strips out a good chunk of your file's original data and uses a lower bitrate. Hence, the sound quality would be considerably lower with a much smaller file size.

However, with proper handling, you wouldn’t even tell the difference, unless you’re using high-quality audio listening pieces of equipment.
