Free Page Speed Checker
Paste any public page URL to measure loading time, page weight, and the biggest slowdowns — explained so you know what to fix first.
What is Page Speed?
A page speed checker loads one page under consistent conditions and measures how long it takes to respond, render main content, and download images, code, and fonts. SlowCheck combines those measurements with PageSpeed / Core Web Vitals when available.
Why it matters
Slow pages frustrate visitors and can hurt conversions. Speed checks help you find the few files or server delays that matter most — not every tiny issue.
Common problems
- Server slow to respond (high TTFB)
- Huge unoptimized images
- Blocking JavaScript and CSS
- Too many third-party scripts
- Missing compression or caching
How to fix them
Start with the top three findings on the report: fix server response first, compress the largest images, then defer non-critical code. Re-scan after each change.
Example
Example: TTFB 1.5s + hero.jpg at 2.8 MB → fix those two first before micro-optimizing fonts.
