WebP is a modern image format developed by Google in 2010. It uses advanced compression technology that produces significantly smaller files compared to PNG and JPG — without any visible reduction in quality.
Google actively recommends WebP as part of its Core Web Vitals and PageSpeed scoring system. Websites that serve images in next-gen formats like WebP get a direct boost in their PageSpeed score, which can improve SEO rankings.
WebP vs JPG vs PNG: Size Comparison
| Format | Typical Size | Quality | Best For | Web Use |
|---|---|---|---|---|
| WebP | Smallest | Excellent | Everything | Recommended |
| JPG | Medium | Good | Photos | Acceptable |
| PNG | Largest | Perfect | Graphics, logos | Too heavy for photos |
WebP files are typically 25–35% smaller than comparable JPG files, and up to 80% smaller than PNG files for photographic images. This means faster page loads, lower bandwidth costs, and better user experience.

Does Converting to WebP Reduce Quality?
Not visibly. WebP uses lossy compression similar to JPG, but with a more efficient algorithm. At the same visual quality level, WebP produces a smaller file. At the same file size, WebP looks noticeably better than JPG.
For transparent images (logos, icons with transparent backgrounds), WebP also supports transparency like PNG — making it a true replacement for both formats.
Do All Browsers Support WebP?
Yes. As of 2024, WebP is supported by all major browsers — Chrome, Firefox, Safari (since iOS 14), Edge, and Opera. Over 97% of global users can view WebP images. It is completely safe to use WebP for your website images.
When Should You Still Use JPG or PNG?
- Keep PNG for icons, logos, and screenshots where you need pixel-perfect sharpness
- Keep JPG if your system or platform does not support WebP uploads (e.g. some older CMSs)
- Use WebP for everything else — hero images, product photos, blog images, thumbnails
