Image compression reduces file size by removing redundant or less important visual information. There are two types: lossless compression, which perfectly preserves image quality by eliminating only redundant data patterns (like PNG), and lossy compression, which achieves much smaller file sizes by discarding visual details that the human eye is less likely to notice (like JPEG). Modern formats like WebP and AVIF offer superior compression by using advanced algorithms that analyze image content and apply different compression strategies to different regions of the image.

Large images are the number one cause of slow-loading websites. According to HTTP Archive, images account for approximately 50% of a typical web page's total weight. Google uses page load speed as a ranking factor, meaning unoptimized images can hurt your search rankings. Compressed images also reduce bandwidth costs for both website owners and visitors, improve user experience (especially on mobile networks), and decrease storage requirements. A well-compressed JPEG can be 60-80% smaller than the original with virtually no visible quality loss.

Choose the right format: use JPEG for photographs, PNG for images requiring transparency, WebP for the best balance of quality and size, and SVG for icons and logos. Aim for images under 200KB for web use. Always resize images to the actual display dimensions before uploading — don't rely on HTML/CSS to scale down a 4000px image to 800px. Use responsive images (srcset attribute) to serve different sizes for different screen widths. Consider lazy-loading images below the fold to improve initial page load time.
