Performance & Tech tool
Measure the full weight of any web page including HTML size, external scripts, stylesheets, images, fonts, and inline code. Check if compression (gzip/Brotli) is enabled and get actionable recommendations to reduce page weight for faster load times.
What it checks
Analyze total page size, resources, and compression.
Inspect protocol, CDN, compression, and response signals where available.
Surface page weight, resource count, app shell clues, or installability signals.
Prioritize fixes that reduce latency, transfer size, or rendering friction.

Interpretation
Use cases
Find infrastructure or payload issues that can affect LCP, CLS, and INP.
Understand how a site is built, delivered, and optimized at the edge.
Retest after releases to catch heavier pages, slower responses, or missing compression.

Frequently asked questions
No. Enter a URL or domain and run the check in your browser. Some results can be partial if the target site blocks requests or hides the data being checked.
The Page Weight Analyzer runs live checks against the target website. Results reflect what was reachable at the time of the test, so retest after changing DNS, redirects, headers, or page content.
Aim for under 200KB of HTML and under 2MB total page weight including images and scripts. Lighter pages usually load faster and are easier to debug.
Yes. Enabling gzip or Brotli compression typically reduces HTML transfer size by 60-80%. Most modern web servers and CDNs support it by default.
There's no hard limit, but each external script adds a DNS lookup, TCP connection, and download time. Sites with more than 15 external scripts should consider bundling, lazy loading, or removing unnecessary third-party tools.
