Page Size / Page Weight Checker FAQs
What's a healthy page weight?+
Under 1 MB is great, 1–2 MB is normal, anything over 3 MB will feel slow on mid-range mobile.
Why does my page weigh so much?+
Usually images (uncompressed or wrong format) followed by JavaScript (heavy frameworks or third-party scripts).
Do you store the URLs I test?+
No. Each measurement is one-shot and discarded after display.
Does this match what Chrome DevTools shows?+
Very close — small differences come from compression, caching state, and asset discovery timing.
Will reducing page weight improve SEO?+
Indirectly — lighter pages have faster LCP and lower bounce, both of which improve Core Web Vitals signals.
