Website Image Optimization: A Practical Guide

Web DesignJuly 30, 2026·14 min·DCL Team

Images are the best and the worst part of a website. Best, because the right photo sells faster than a hundred words. Worst, because unoptimized images are the main reason sites load slowly on mobile and lose visitors right when they were about to buy.

The fixes are simple: choose the right format (WebP or JPG for photos, SVG for logos, PNG for transparency), size images to how they are actually displayed, compress before uploading, use lazy loading, and add descriptive alt text that helps both screen readers and Google image search.

Always use images you have the legal right to. Prefer your own photos, licensed stock or verified free banks. Never pull images straight from Google, which can expose you to copyright claims.
