Step-by-Step Guide

Start with high-quality source images

Always work from the highest quality originals. You can compress down but can't add quality back. AI upscaling can help recover detail from lower-res images if needed.

Pro Tip: Keep original high-res files archived, work with copies.

Choose the right format

WebP offers the best compression with quality. Use it for web when possible. Fall back to JPG for compatibility. PNG only when you need transparency.

Pro Tip: WebP is 25-35% smaller than JPG at the same quality.

Resize to actual display size

Don't serve 4000px images that display at 500px. Resize images to 2x their display size for retina screens (1000px for 500px display).

Pro Tip: Create multiple sizes for responsive images: thumbnail, medium, large.

Compress intelligently

Use quality settings of 80-85% for JPG/WebP. Most viewers can't see the difference, but file sizes drop dramatically.

Pro Tip: For hero images, use slightly higher quality (90%). For thumbnails, go lower (70%).

Implement lazy loading

Only load images as users scroll to them. This dramatically improves initial page load. Modern browsers support native lazy loading with the loading='lazy' attribute.

Pro Tip: Don't lazy load above-the-fold images - load those immediately.
