Although Hugo generates fast static sites by nature, unoptimized images can completely cancel out this advantage. I decided to investigate this using my own website as a case study.</p> <p>Analysis in Chrome DevTools clearly showed the source of the problem. Images made up 96% of the total transfer, adding up to nearly 15 MB. I identified three large PNG files that caused most of this traffic and increased the load time to over 4 seconds. For mobile users, this meant a long wait and wasted data.</p>
