Lighthouse image optimization tips

Use these before you upload or share the page.

The 'Efficiently encode images' warning means you can save 20-50% file size by compressing. Run flagged images through Skwish at 80% quality and re-audit.

The 'Properly size images' warning means images are larger than their display size. Use Skwish's resize controls to match the display dimensions, then compress.

Next.js and Cloudflare Images users: compress originals before uploading to your image pipeline. Smaller originals mean smaller CDN-cached versions and faster LCP.
