This is particularly important for WordPress bloggers, who often use many images in their posts, including site listings, galleries, and how-to guides.
Over time, the upload folder for images can become quite large, affecting the load time of each web page. While manually optimizing images might seem time-consuming, it’s crucial for maintaining site speed. Fortunately, there are several free and premium WordPress lossless image compression plugins available that can streamline this process.
