Why Image Optimization is Essential for Website Performance
Image optimization plays a critical role in website performance, directly influencing loading times, user experience, and SEO rankings. Websites with large image files take longer to load, which can frustrate visitors and lead to higher bounce rates. Studies show that 47% of users expect a webpage to load in two seconds or less, and a delay of even a few seconds can reduce conversion rates significantly. Additionally, search engines like Google consider site speed as a ranking factor, so optimizing your images can improve your site’s SEO. By compressing and resizing images without compromising quality, you enhance your website’s speed, accessibility, and overall performance, ultimately improving user engagement and retention.
