Image Compression

Image compression is the technical process of reducing the file size of an image without noticeably degrading its visual quality. Unoptimized, massive image files are the leading cause of failed Core Web Vitals, specifically destroying the Largest Contentful Paint (LCP) metric and artificially inflating page load times. Technical SEO requires aggressive, lossless or lossy compression algorithms to shrink high-resolution hero images and product photos to fractions of their original size. Serving uncompressed, multi-megabyte images is an unacceptable technical failure that directly sabotages organic rankings by providing a sluggish, frustrating user experience.

Image Compression Simplified

Image compression is the process of shrinking the massive file sizes of your photos before you upload them to your website. If you don’t compress your images, they will take forever to load on a mobile phone, and Google will penalize your rankings.
