How to Convert Images to WebP for Your Website
- 1
Upload your site image
Select a JPG or PNG currently used on your website. Hero images, product photos, and blog graphics benefit most.
- 2
Set WebP quality
80% quality is the sweet spot for web images. It's visually equivalent to a JPG at 90% but 30% smaller in file size.

Replace on your site
Download the WebP file and swap it with the original on your server. Update your HTML src attributes or use the <picture> element for fallback support.
Google Literally Tells You to Use WebP
Run any page through Google's PageSpeed Insights and if you're serving JPG or PNG images, you'll see the recommendation: 'Serve images in next-gen formats.' WebP is what they mean. Google created the format and their ranking algorithm favors sites that use it.
The numbers are concrete. A typical blog post with five images at 300KB each (JPG) totals 1.5MB of image data. Convert all five to WebP at 80% quality and that drops to about 900KB. That's 600KB less data your visitors download, which translates to 0.5-1 second faster LCP on average mobile connections.
For implementation, the cleanest approach is the HTML <picture> element. Serve WebP to browsers that support it (99%+ of traffic) and fall back to JPG for the rest. Most CMS platforms and CDNs now handle this automatically.
