Optimize images for Core Web Vitals

Core Web Vitals measure how fast and stable your pages feel. Images directly affect LCP (loading speed) and CLS (layout stability). Skwish compresses your JPG, PNG, and WebP files locally — smaller images mean better scores without uploading to a server.

Core Web Vitals image tips

Use these before you upload or share the page.

LCP is usually the largest image in the viewport — find it with Lighthouse, compress it in Skwish, and re-test. A 40-60% size reduction on the LCP element is common.

CLS from images happens when dimensions aren't set — always add width and height attributes, then compress. Smaller files load faster, reducing the window for layout shifts.

WebP typically scores better on LCP than JPEG at equivalent visual quality. Use Skwish's format conversion to compare both options before deploying.
