Web tips
⚡
Every 100 KB saved per image adds up quickly — a page with 10 images becomes 1 MB smaller, which dramatically improves load times on mobile.
📐
1920 px covers full-width hero images on most desktop screens. Scale down smaller images to their actual display size for maximum savings.
🌐
Use WebP format when possible — it's 25–35% smaller than JPEG at the same quality and is supported by 97% of browsers.
🔍
Google PageSpeed and Core Web Vitals reward fast images. Pre-compression is the easiest way to improve your scores.
