Introduction
Images play an important role in website design, but large image files can significantly slow down page loading speed. Slow websites often lead to higher bounce rates, lower user engagement, and reduced search engine visibility. Many website owners upload high-resolution images directly from cameras or design tools without optimizing them, which increases page size and affects overall performance.
This creates a common challenge: how do you maintain image quality while reducing file size? Without proper compression and resizing, websites can become heavy and difficult to load, especially on mobile devices or slower internet connections. Fortunately, several free online tools make image optimization simple and accessible.
