Why optimize images?
Faster images improve Core Web Vitals (LCP, INP), rankings, and conversions — while cutting bandwidth and storage costs.
Page speed = SEO wins
Images are often the heaviest assets on your pages. Shrinking them reduces load time, improves Largest Contentful Paint, and leads to better search visibility and happier users.
Modern formats
WebP averages 25–35% smaller than JPEG/PNG at similar quality. This tool exports to WebP by default (with a safe JPEG fallback if your browser can’t encode WebP).
Smart compression
Enable SEO Image Enhancer for adaptive quality: large originals are nudged lower to keep visual quality while maximizing byte-savings.
Right-sized dimensions
Don’t ship a 4000px image into a 1200px space. Use the optional width/height caps to preserve aspect ratio and avoid waste.
Best practices & tips
Serve responsive images
Use srcset and sizes with the WebP outputs to deliver the smallest acceptable image for each viewport.
Lazy-load below-the-fold
Add loading="lazy" to images that don’t appear immediately on screen.
Keep filenames meaningful
Descriptive names (e.g., blue-running-shoes.webp) help image search and analytics.
