Images often account for 50–70% of a webpage's total size. Optimizing images is one of the fastest ways to improve loading times and user experience, especially on mobile devices.
Why image optimization matters
- Faster page loads improve user experience and reduce bounce rates.
- Better SEO rankings from improved Core Web Vitals scores.
- Lower bandwidth costs, especially important for mobile users.
- Better performance on slower connections.
Tools for image optimization
TinyPNG / TinyJPG
These tools compress PNG and JPEG files by up to 70% without noticeable quality loss. Simply upload your images and download the optimized versions.
WebP format
WebP provides superior compression compared to JPEG and PNG. Modern browsers support WebP, and you can serve fallbacks for older browsers.
