What Is WebP and Why Should You Care?
WebP is a modern image format developed by Google that provides superior compression compared to both JPG and PNG — at equivalent visual quality. According to Google's own research, WebP lossless images are 26% smaller than PNG, and WebP lossy images are 25–34% smaller than comparable JPG images.
For website owners, this translates directly into faster page loads, lower bandwidth costs, better Google PageSpeed scores, and improved Core Web Vitals — all of which are factors in Google search ranking.
WebP Supports Everything You Need
- Lossy compression — like JPG, ideal for photographs
- Lossless compression — like PNG, perfect for graphics and logos
- Transparency (alpha channel) — like PNG, but much smaller files
- Animation — like GIF, but far smaller file sizes
This versatility means WebP can replace JPG, PNG, and GIF on your website with a single format.
Browser Support in 2026
WebP is supported by over 97% of all browsers globally, including Chrome, Firefox, Safari (since 2020), Edge, and all modern mobile browsers. For the remaining ~3%, you can provide JPG or PNG fallbacks using the HTML <picture> element.

Implementing WebP on Your Website
The simplest approach is to replace image files with WebP versions and update your HTML references. For full cross-browser support, use the picture element:
<picture>
<source srcset="image.webp" type="image/webp">
<img src="image.jpg" alt="Description">
</picture>Modern browsers pick the WebP source; older browsers fall back to the JPG automatically.
Recommended Quality Settings
- Product images and photographs: 80–90%
- Hero images and banners: 85–92%
- Logos and icons (use lossless WebP): 100%
- Thumbnails: 75–80%
Measuring the Impact
After converting your images to WebP, test your page speed at Google PageSpeed Insights (pagespeed.web.dev). A website switching from JPG/PNG to WebP typically sees a 20–40% reduction in total page weight and a corresponding improvement in load time scores.
