How do I make my landing page load fast on a slow 4G phone in India?
The short answer
Most of your load time is unoptimized images and heavy page builders, so compress every image, serve them as WebP, and cut fonts down to one family. Test on a real mid-range Android over mobile data, not your office wifi, because that's what your customer actually has. If you can hit a good score on PageSpeed Insights with mobile throttling, you're ahead of most polished-looking sites.

Instead of vague advice it links to specific, hands-on guides you can work through one at a time. Treat it as a starting point and a menu: fix the biggest offenders PageSpeed flagged for you, do not try to do all of it at once.

Optimizing images (right format, compression, responsive sizes, lazy loading) gives you the biggest speed win for the least effort.
Web fonts silently block your text from showing, so subset them and use font-display: swap so copy renders immediately.
Cutting and splitting JavaScript matters most for low-end phones common outside the big metros, where the CPU, not just the network, is the bottleneck.
Why we picked it
This is the standard free tool for measuring how your page actually performs, and it defaults to a mobile view, which is exactly what you want when most of your visitors are on a phone. It runs your page on a throttled connection and gives you real Core Web Vitals plus a prioritized list of what is slowing you down. Start here: measure before you change anything, so you know whether your fixes actually helped.

Images are the single biggest reason landing pages crawl on a slow 4G connection, and Squoosh fixes that in your browser with nothing to install. You drag in a photo, convert it to WebP, and watch the file size drop with a live before and after comparison, often from over a megabyte down to under 100 KB. Everything runs locally on your device, so nothing gets uploaded anywhere.
