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.

Why convert JPG to WebP?

Faster page load times

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.

Better Core Web Vitals scores

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.

All modern browsers support it

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.

Frequently asked questions

How much smaller will the WebP be?

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.

Does WebP support transparency?

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.

Will WebP work on all platforms?

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.
