The difference between them is enormous. And it plays an essential role in file size, the primary factor that affects how long it takes for the image to load.

What is WebP and Why It Matters?
The WebP format was introduced by Google in 2010. It was designed specifically for websites, allowing images to maintain high quality while using much smaller file sizes than PNG or JPG. If you need a different image format, you can also convert PNG to JPG for broader device and application compatibility. WebP achieves its smaller file sizes by using an advanced compression algorithm that is more efficient than traditional PNG and JPG compression.
Many website owners convert PNG to WebP to reduce image size while maintaining excellent visual quality. This results in a significant reduction in image file size. Compared with a similar PNG file, a WebP file is 25–35% smaller. Without any loss in image quality, it presents. For websites with lots of pictures used — photo galleries, blog entries, portfolio sites.
It is important to reduce the amount of data sent to the user as much as possible, and this format provides that option. For instance, if 2 MB of PNG images were transferred from a homepage in the past. Now the same images can be transferred in under 1.4 MB using WebP.
Besides its compression functionality, WebP provides additional features, including transparency (as in PNG images), animations (as in GIF images), and colors. WebP images are supported in all recent browsers, including Chrome, Firefox, Safari, and Microsoft Edge. This makes WebP a good file format for practically any web development project. Even Google considers website speed when ranking websites.

Understanding these differences makes it easier to convert PNG to WebP for websites that need faster loading speeds.
The PNG format is used to create images with transparent backgrounds, such as icons, logos, interface elements, and product images. This format preserves image data when saving. One disadvantage of the PNG format is that its lossless nature results in larger files than WebP.
Unlike PNG, WebP has been developed with web delivery in mind, and its lossless compression makes files about 26 percent smaller than PNGs of the same quality, according to tests by Google. With lossy compression (acceptable in many cases on the web), the difference is even more significant.
It should be noted, however, that the downside of WebP is its limited compatibility with offline design programs and printing workflows. And that is why PNGs are saved as originals, while WebP is used for web graphics in their copy.
Why Convert PNG to WebP
Faster Page Load Speeds
Page load speed is one of the most immediate factors affecting the user experience. Time after time, it has been proven that users leave web pages that do not load sufficiently fast within just a couple of seconds.
Given that the WebP format is far less heavy than the PNG image format. Using the former would make the entire web page lighter and thus load faster, especially on mobile networks. Many website owners convert PNG to WebP because smaller image files help pages load faster.
That may make all the difference for highly frequented web pages, as even a fraction of a second reduction in page load speed can affect bounce rates. Specifically with e-commerce web pages. When you convert PNG to WebP, visitors spend less time waiting for images to load.
Better Core Web Vitals Scores
Google’s Core Web Vitals, especially Largest Contentful Paint (LCP), indicate how quickly the main content on the page loads. Oversized, non-optimized PNG files are the most common reason for poor LCP scores. A PNG-to-WebP converter is one of the very first tips developers get from auditing pages with Google Lighthouse or PageSpeed Insights. Developers often convert PNG to WebP to improve Largest Contentful Paint (LCP) scores.
Reduced Bandwidth and Hosting Costs
All images uploaded and displayed on your site use bandwidth. When dealing with highly trafficked sites. Using WebP images in place of large PNG files helps decrease bandwidth usage. Depending on the hosting service you use, you may save money. Businesses that regularly convert PNG to WebP can reduce bandwidth usage and hosting costs.
Maintained Image Quality
The main concern people have about converting PNG to WebP format is the loss of image quality. In fact, WebP’s lossless image compression maintains image quality. Thus, completely replacing the PNG images on the Internet. Moreover, even with WebP lossy compression at high quality, the image remains identical.
