What's weighing your website down?
Enter your URL — we'll scan your page and show you exactly what's bloating your load time, starting with the biggest wins.
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 optimisation — 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, a WordPress image optimisation plugin.
- Why does it analyse 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 centre rather than a visitor’s device, scores may differ slightly from real-world experience — location, device speed, and network conditions all affect actual performance.
