In the race for Google rankings, speed is everything. Google's "Core Web Vitals" update made page speed a direct ranking factor. And the #1 reason for slow websites? Unoptimized, heavy images.

The Speed-SEO Connection
Google loves fast sites because users love fast sites.
- Bounce Rate: As page load time goes from 1s to 3s, the probability of bounce increases 32%.
- Crawling Budget: Googlebot can crawl more pages on your site if they load faster.
- Mobile Experience: Large images eat up user data and battery, leading to a poor mobile experience.
Lossy vs. Lossless Compression
Lossless: Reduces file size without removing any pixel data (e.g., removing metadata). Ideal for medical imaging or archival photos.
Lossy (Best for Web): Significantly reduces file size (up to 90%) by removing data that the human eye cannot perceive. This is the standard for websites.

Why You Switch to WebP
WebP is a modern image format derived from the VP8 video codec. It provides superior lossless and lossy compression for images on the web.
- WebP lossless images are 26% smaller than PNGs.
- WebP lossy images are 25-34% smaller than JPEG images.
