WebP images are 25–35% smaller than JPG at the same visual quality. Converting your JPGs to WebP is one of the fastest wins for website performance and Google PageSpeed scores.
Why convert JPG to WebP?
- Smaller files, faster pages — a 200 KB JPG typically becomes a 130–150 KB WebP at the same quality. For image-heavy pages, this adds up significantly.
- Better Core Web Vitals — Google explicitly recommends WebP in PageSpeed Insights. Switching to WebP can improve LCP (Largest Contentful Paint) scores.
- Full browser support — all modern browsers (Chrome, Firefox, Safari, Edge) support WebP. It is safe to use on any current website.
- WordPress — WordPress 5.8+ supports WebP natively. Upload WebP directly instead of JPG for better performance.
When to keep JPG
- Sending images by email — many email clients and older software do not support WebP.
- Sharing with people who may open the file in older apps (Photoshop CS6 and older, Windows Photo Viewer).
- Printing — use JPG or TIFF for print; WebP is a web format.

Quality settings for JPG to WebP
WebP quality works similarly to JPG but achieves smaller files at the same perceptual quality:
- 85–90% — recommended default. Smaller than equivalent JPG with no visible difference.
- 75–84% — good for web thumbnails and images where speed matters most.
- 100% — lossless WebP. Use for graphics, logos, and images with flat colours.
