Page Size Checker is a free SEO tool that analyzes the total download size and resource breakdown of any web page. Understanding page weight is crucial for optimizing website performance, improving Core Web Vitals, and delivering fast user experiences across all devices and network conditions.
The tool fetches all resources loaded by a page — HTML, CSS, JavaScript, images, fonts, and other assets — providing a detailed breakdown showing exactly which resource types consume the most bandwidth. With insights into total size, HTTP request count, and load time, you can identify optimization opportunities at a glance.
Page size directly impacts SEO rankings and user engagement. Studies show that 53% of mobile users abandon pages taking longer than 3 seconds to load. By keeping page size under 1-2MB and minimizing requests, you can reduce bounce rates, improve conversion rates, and achieve better search engine rankings.
