Next-Gen Image Optimization: Why and When to Convert to WebP

By Web Performance Team

Images account for more than 60% of the total byte weight of average web pages. Adopting modern image formats like WebP is one of the highest-leverage optimizations for Google Core Web Vitals and user retention.

What Is WebP?

Developed by Google, WebP is a modern image format that provides superior lossy and lossless compression. According to comparative benchmark studies:

  • WebP lossless images are 26% smaller than comparable PNG files.
  • WebP lossy images are 25% to 34% smaller than comparable JPEG images at equivalent visual quality.
  • WebP natively supports transparency (alpha channel) at a fraction of PNG file sizes.

Browser Compatibility Today

Historically, developers hesitated to adopt WebP due to lack of support in older browsers. Today, WebP is natively supported across over 97% of global web browsers, including modern Chrome, Safari, Firefox, Edge, iOS, and Android.
