WebP is Google's modern image format that produces files 25–35% smaller than JPG at equivalent visual quality — making it the best format for images on websites, landing pages, and web apps. Converting your JPGs to WebP is the quickest way to speed up a website without touching any code.
Smaller image files mean faster downloads. A page with 10 JPG images at 200 KB each becomes a page with 10 WebP images at ~130 KB each — a 35% reduction in image payload with no visible difference.
Google's LCP (Largest Contentful Paint) and overall PageSpeed Insights score both improve when you serve images in WebP. It's one of the highest-impact, lowest-effort optimisations for any website.
Chrome, Firefox, Safari (since 2020), and Edge all natively display WebP. Over 96% of global browser users can view WebP images without any fallback needed.
For photographs, expect 25–35% smaller than the equivalent JPG at similar visual quality. Results vary by image content — high-detail photos compress better than flat graphics.
Yes. WebP supports an alpha channel just like PNG. If you convert a JPG (which has no transparency) to WebP, the result is an opaque WebP — but WebP can store transparent images when the source has one.
All modern browsers (Chrome, Firefox, Safari, Edge) support WebP. Some older email clients and desktop apps don't. For maximum compatibility use JPG; for web use, WebP is the better choice.
