Using WebP thumbnails, YouTube significantly boosted page loading speed, reducing load time by 10%.

Ready to boost your website’s performance? Let’s get started!

Why Should You Convert PNG Images to WebP?

WebP is the modern image format and Google’s recommended image format.

PNG supports only lossless compression, which makes its file size larger. On the other hand, WebP provides superior lossy and lossless compression. Thus, the WebP file size is smaller than PNG.

WebP lossless images are 26% smaller than PNGs. This reduction helps to reduce web page size significantly. Therefore, improves web page loading speed, which boosts user experience and ranking on the SERP.

WebP images can reduce bandwidth use significantly for websites that use many images. It also makes web browsing smoother for devices with a slower internet connection.

PNG doesn’t support natively. On the other hand, WebP supports animation.

WebP is better than PNG in many ways, providing more benefits.
