Image Optimization: The Fastest Way to Speed Up Your Website

Oversized, uncompressed images are the single most common cause of slow load times on small business websites — a page with several large, full-resolution photos can add several seconds to load time on its own.

This is also one of the easiest issues to fix, since it doesn't require touching design, layout, or functionality at all.

Compressing images to reduce file size with minimal visible quality loss, using appropriately sized dimensions rather than a much larger original file scaled down by the browser, and using modern, efficient image formats all contribute to faster load times.

Lazy loading — only loading images as a visitor scrolls to them, rather than all at once — can also meaningfully improve initial page load speed for image-heavy pages.

Google's PageSpeed Insights tool identifies specific images that are unnecessarily large or improperly formatted, giving you a concrete list of what to fix rather than a vague sense that images "might be an issue."

This is worth checking periodically, since new images added over time can quietly reintroduce the same problem if optimization isn't part of your regular content process.
