Measure the HTML size of a page and count its linked resources.
A page size checker measures the downloaded HTML and counts the scripts, stylesheets and images the page references. Heavy pages load slower, especially on mobile networks.
This tool fetches the address you enter once, from our server, and reports what a crawler would receive. The URL is not stored; only a short-lived rate-limit counter is kept. Results show the page at the moment of the check and can differ from what a logged-in browser or a bot with different headers sees.
Reads the real page at the moment you run it, with every redirect followed and shown.
Each finding says what it means and what to do next, not just a raw value.
Copy the output straight into your CMS, spreadsheet, ticket or client report.
Free, with no signup. Fair-use limits keep the tool fast for everyone.
Use a full public URL.
The page is fetched live from our server.
Apply the fixes, then run it again.
Look at the downloaded HTML size and the number of scripts, stylesheets and images referenced. Large HTML often points to bloated markup, inline data or page builder output. A high script count suggests third-party tags, plugins or unused libraries that delay interactivity. Many image references call for lazy loading, modern formats such as WebP or AVIF, and correct dimensions. Prioritise removal over optimisation: delete unused plugins and tags first, then defer or async non-critical scripts, combine where sensible and compress what remains. Retest the same URL after each change so you can see which action made the difference, and confirm with PageSpeed Insights.
Judging a page only by HTML size misses the real weight, since images, fonts and scripts usually dwarf it, and this tool counts references rather than measuring every file. Minifying a few files while keeping a dozen unused third-party scripts achieves little. Lazy loading the main hero image can slow the largest contentful paint, so leave above-the-fold images eager. Another mistake is chasing a specific kilobyte target without regard to user experience. Do not compare a simple article page with a product page that has galleries and widgets. Test the templates that matter, such as home, category and article, and watch trends over time.
