Why Compress Images?

Large image files slow down websites, consume mobile data and take up unnecessary storage space. Image compression reduces file size while preserving visual quality — making your website load faster, improving Google PageSpeed scores and saving bandwidth. Google's Core Web Vitals directly rewards faster image loading with better search rankings.

How Image Compression Works

There are two types of image compression:

Lossy compression — permanently removes some image data that the human eye barely notices. Used for JPG/JPEG files. Achieves 60–80% size reduction with minimal visible quality loss.
Lossless compression — compresses without removing any image data. Used for PNG files. Achieves 20–40% size reduction with zero quality loss.
