What PageWeight checks

PageWeight runs your URL through Google PageSpeed Insights — the same engine behind Google Search Console — and translates the raw data into plain English. Each scan checks:

  • Image optimization — identifies images that could be re-encoded as AVIF or WebP, with exact savings per file
  • Core Web Vitals — how quickly your main content loads, when content first appears, interaction delays, and layout stability
  • Third-party scripts — which external tools (analytics, ads, chat widgets) are blocking your page and by how much
  • Render-blocking resources — JavaScript or CSS delaying the browser from displaying your page
  • Unused JavaScript and CSS — code downloaded by visitors but never executed
  • Server response time — how long your server takes to respond before the browser can load anything
  • Text compression — whether your server sends HTML, CSS, and JS compressed with gzip or brotli

Why page weight matters

Page weight — the total size of all files a browser must download to display your page — directly affects how fast your site loads. Google uses Core Web Vitals as a ranking signal for mobile search. Images typically account for 50–80% of total page weight on most sites, making them the highest-impact place to start.

Slow sites lose visitors before the page finishes loading. A one-second delay in mobile page load time can reduce conversions by up to 20%.

Common questions

How does PageWeight work?
We send your URL to the Google PageSpeed Insights API and present the results in plain English. PageWeight is powered by Google’s Lighthouse engine — the same technology behind the Performance tab in Chrome DevTools.
Is it free?
Yes, completely free with no account or signup required. PageWeight is a free tool by Picqlo, an image optimization service for WordPress and beyond.
Why does it analyze the mobile version of my site?
Google uses mobile-first indexing — your search ranking is based on how the mobile version of your site performs. Mobile performance is the most important measure for both SEO and real-world user experience.
What does the performance score mean?
Scores of 90–100 are considered fast, 50–89 need improvement, and below 50 are poor. The score is a weighted combination of Core Web Vitals and other performance metrics, calculated by Google’s Lighthouse engine.
How accurate are the results?
Results come from the same Lighthouse engine used by Google Search Console. Because the analysis runs from a Google data center rather than a visitor’s device, scores may differ slightly from real-world experience — location, device speed, and network conditions all affect actual performance.
