A landing page that finally passed the Lighthouse audit
You're shipping a landing page on Friday and Lighthouse keeps flagging your hero image. The PNG you exported from Figma is 2.4 MB and the page weight is killing your Largest Contentful Paint score. The marketing team picked the image, you don't have time to renegotiate.
You drop the PNG into the converter, leave quality on the default 85, and get back a 380 KB WEBP that looks identical at hero size. You swap the asset, push the change, and Lighthouse goes from 67 to 94 on performance. The marketing team never noticed the difference visually.
Six MB of hero images on the site became 1.1 MB total. Same look, faster load.
