speed-lens

Enter a URL — it pulls a PageSpeed Insights audit and loads the page in a real browser to measure every image's actual rendered size, then shows the bytes you can save by resizing + WebP. Optimized images ready to download.

Tip: paste a product or landing page — that's where oversized hero images usually hide.

SlowExpert read of this page's load speed

Lighthouse scores this page 40/100 on mobile — slow. The main drag is Largest Contentful Paint, First Contentful Paint, Speed Index, and Time to Interactive (28.6 s, 14.8 s, 21.9 s, 30.2 s). Compress/preload the LCP image and cut render-blocking CSS & JS. On image weight specifically, you're shipping 10.7 MB (88%) more than needed across 150 images — and since LCP is weak, right-sizing the hero image is the single highest-leverage fix here.

Cut 10.7 MB of image weight (resize to render size + WebP) — see the table below.
Largest Contentful Paint (28.6 s): compress/preload the LCP image and cut render-blocking CSS & JS.
First Contentful Paint (14.8 s): lower server response time (TTFB) and remove render-blocking resources.
Speed Index (21.9 s): prioritize above-the-fold content and defer offscreen work.
Time to Interactive (30.2 s): reduce JavaScript execution and defer non-critical scripts.

Largest Contentful Paint

28.6 s

how long until the biggest thing above the fold (usually the hero image or headline) finishes painting — a problem here (target ≤ 2.5s).

First Contentful Paint

14.8 s

how long until the very first text or image shows up — a problem here (target ≤ 1.8s).

Speed Index

21.9 s

how quickly the page visually fills in — a problem here (target ≤ 3.4s).

Total Blocking Time

580 ms

how long the main thread was frozen — i.e. how long taps/clicks feel dead — needs work here (target ≤ 200ms).

Cumulative Layout Shift

0.006

how much the layout jumps around while loading — healthy here (target ≤ 0.1).

Time to Interactive

30.2 s

how long until the page reliably responds to input — a problem here (target ≤ 3.8s).
