Public settings
Choose how the public checker should discover and measure page resources.
Free public checks are limited to 3 uses/day. CAPTCHA may appear for rendered analysis.
Find the assets that make a page heavy
Use Wranker’s Page Size Checker as a lightweight page-weight diagnostic before running deeper performance and Core Web Vitals checks.
Use it during internal linking audits, content optimisation, technical SEO reviews, website migrations and content hub planning.
Measure total page size
Review total transferred size and uncompressed size where available, so heavy pages can be identified quickly.
Break down resource categories
Separate HTML, CSS, JavaScript, images, fonts, other resources and third-party weight to see what contributes most.
Check gzip and Brotli coverage
Spot text-based resources where compression is good, partial, missing or unknown before deeper performance work.
Preview the heaviest files
Use the public waterfall preview to focus on large files, first-party assets, third-party resources and uncompressed text assets.
Page weight is the first signal before
A page can feel slow for many reasons, but heavy images, JavaScript, CSS, fonts, third-party scripts and uncompressed text assets are common places to start. This checker helps you decide what to optimise first without turning the landing page into a full performance report.
Prioritise the right fixes
See whether images, JavaScript, CSS, fonts, compression or third-party assets deserve attention first.
Start audits with clearer context
Use page-weight diagnostics before running Page Speed Insight Checker or Core Web Vitals Checker.
Create practical next steps
Turn basic size signals into rule-based actions like resizing images, reducing bundles, limiting fonts and reviewing scripts.

Page Size Checker FAQs
Clear answers about page weight, transferred size, compression and how this tool fits into performance diagnostics.
Page size is the total amount of data a webpage transfers when its HTML, CSS, JavaScript, images, fonts and other resources are loaded or discovered.
Enter a public page URL and click Run Size Check. Wranker measures the page and shows total size, request count, asset breakdown, compression status and the largest detected resources.
As a public guideline, a page up to 1.5 MB is treated as Good, 1.5–3 MB as Warning and more than 3 MB as Poor. Final thresholds may vary by page type, business goal and performance requirements.
Large images, oversized JavaScript bundles, unused CSS, too many fonts, third-party scripts, ads, embeds and missing compression are common causes of heavy pages.
No. Page Size Checker focuses on asset weight and requests. Use Core Web Vitals Checker or Page Speed Insight Checker for LCP, INP, CLS and performance diagnostics.
Transferred size is the amount of data downloaded by the browser after compression is applied. It is often smaller than uncompressed size.
Uncompressed size is the original size of a resource before gzip, Brotli or other compression is applied.
Yes, for most reviews. Third-party scripts, fonts, analytics, ads and widgets contribute to real page weight and should be included when evaluating the loaded page.
Some resources may be blocked, missing size headers, hidden by CORS restrictions, affected by redirects, protected by bot systems or unavailable in fast fetch mode.
Yes. Where export is available, you can download the public result as CSV or PDF.
