Why Image Compression Matters for Fast Websites
Uncompressed images are one of the leading causes of sluggish webpage loading times, poor Google Core Web Vitals scores, and high mobile data consumption. By compressing images prior to publication, you can reduce bandwidth overhead by 40% to 80% with virtually imperceptible differences in visual fidelity.
