Boost Web Speed with AI-Driven Image Hacks

AIToolsNova Your page is slow because of one 6 MB photo. Finding and fixing it takes about ten minutes. Swipe up →

Find the culprit

Step 1 of 7 Open DevTools → Network → sort by size. It is almost always a hero image, not your code. Fix the biggest file first.

Resize before compress

Step 2 of 7 Do not ship a 4000px photo into an 800px slot. Resize to display size first, then compress — the order matters.

Compress at 70–80

Step 3 of 7 JPG quality 75 is invisible to most eyes and cuts 60–80% of the weight. Browser-side compressors mean the file never leaves your machine.

WebP, with one exception

Step 4 of 7 Converting big JPG/PNG to WebP saves another ~30%. Keep PNG only for screenshots and logos with sharp text — WebP can smear fine edges at low quality.

Lazy-load the right things

Step 5 of 7 loading="lazy" on below-the-fold images is one attribute. Do not lazy-load the hero image — that delays the first thing people see.

Test on a real phone

Step 6 of 7 Desktop Wi-Fi lies to you. Check the page on a mid-range Android over 4G — that is the connection most of your visitors have.

The honest limit

Step 7 of 7 Compression cannot save a page with forty images. Cut the gallery to the eight that actually sell the thing.
