Why Compress Images?

A single photo from a modern smartphone can easily be 3-5 MB. Put a few of those on a web page and your load time tanks. Google's Core Web Vitals count page speed as a ranking factor, so oversized images hurt your SEO directly. Compression typically cuts 60-80% of the file size with no visible quality loss. It's worth doing before uploading to any blog, e-commerce site, or social platform.

Which Format to Pick

Format	Best for
JPEG	Photos and color-rich images. High compression but no transparency support
PNG	Screenshots, icons, images that need transparency. Larger file sizes
WebP	Google's format — 25-30% smaller than JPEG at the same quality, supports transparency
