The Page Size Checker by seochecker.tools helps you measure the total size of any webpage, including HTML, CSS, JavaScript, images, and other resources. It’s an essential tool for optimizing website speed and performance.
Page size plays a crucial role in how fast your site loads. A heavier page leads to slower load times, which negatively impacts user experience, bounce rate, and SEO rankings—especially on mobile networks.
