Fast Load Checker (< 2s)

Analyze your HTML to estimate page load time and verify it meets the 2-second threshold. Checks render-blocking resources, asset counts, document size, and common performance anti-patterns.

Page HTML

How It Works

This tool parses your HTML to estimate whether a page can load within 2 seconds on a typical 4G connection. It counts external resources, identifies render-blocking elements, and applies a heuristic time budget model based on real-world performance benchmarks.

What It Checks
  • Render-blocking resources — synchronous CSS and JS in <head> that delay first paint
  • External request count — each request adds DNS, connection, and transfer time
  • HTML document size — large documents increase time-to-first-byte
  • Image optimization — lazy loading, dimensions, and modern format usage
  • Script loading strategy — async/defer attributes on scripts
  • Font loading — font-display, preload hints, and @font-face rules
  • Resource hints — preconnect, preload, and dns-prefetch
Time Budget Model
  • DNS + Connection: ~100ms per unique origin
  • TTFB: 200–600ms depending on HTML size
  • Blocking CSS: ~80ms per stylesheet in head
  • Blocking JS: ~120ms per synchronous script in head
  • Images: ~50ms per image (parallel, after first paint)
  • Fonts: ~100ms per custom font face
Note: This is a structural estimate based on HTML analysis. Real load times depend on server speed, network conditions, and asset file sizes. Use browser DevTools or Lighthouse for live measurements.
