Image Compression Tips & Best Practices
Use WebP format for web — 25-35% smaller than JPEG at equivalent quality
For photographs, JPEG quality 75-85% is the sweet spot with minimal visible loss
For graphics and logos with transparency, use PNG format
Resize images to their display dimensions — don’t serve 4000px images in 800px containers
Use batch processing to optimize an entire page’s images at once
Compress images before uploading to your CMS to avoid re-compression artifacts
