Page speed matters more than ever, both for keeping visitors on your site and for ranking well in Google. One of the easiest wins is switching your images from JPG to WebP, a format built specifically for the modern web. Here is why it matters and how to convert your files in seconds.
What Is WebP?
WebP is an image format developed by Google that uses advanced compression to produce smaller files than JPG or PNG while keeping visual quality close to the original. It supports lossy and lossless compression, along with transparency and animation, all in a single format built for fast websites.
Why Google Recommends WebP for Websites
Google actively recommends WebP because smaller image files load faster, which directly improves Core Web Vitals metrics like Largest Contentful Paint. Faster-loading pages create a better user experience, lower bounce rates, and can give your site a slight edge in search rankings. Google’s own WebP documentation shows that WebP images are typically 25-35% smaller than comparable JPGs at the same visual quality.
How Much Smaller Is WebP Than JPG?
In real-world testing, WebP files are commonly 25 to 35% smaller than JPGs of equivalent quality, and sometimes even more for photos with lots of flat color or repeating patterns. For a site with hundreds of images, that adds up to a meaningfully faster load time and lower bandwidth costs.

Impact on Core Web Vitals and SEO
Smaller image files reduce the time it takes for your page to finish loading its main content, which is exactly what Largest Contentful Paint measures. Since Google factors page experience into search rankings, switching to WebP is a simple, low-effort way to improve both user experience and your site’s visibility in search results. It’s also worth pairing WebP conversion with general image optimization best practices for the best results.
