PNG (Portable Network Graphics) is a lossless image format commonly used for graphics, illustrations, logos, icons and screenshots. One of its biggest advantages is support for transparent backgrounds, making it a popular choice for designers and developers. Although PNG offers excellent quality, its files are often much larger than modern image formats. Large PNG files increase website loading time, consume more bandwidth and may negatively affect user experience, especially on mobile devices.
WebP is a next-generation image format created by Google. It supports both lossy and lossless compression while also preserving transparency. Compared to PNG, WebP images are typically 25–35% smaller at similar visual quality. Because WebP produces much smaller files, websites load faster, visitors download fewer bytes and servers use less bandwidth. Most modern browsers fully support the WebP format.
Choosing between PNG and WebP depends on how the image will be used. PNG is still an excellent choice for editing, design work and situations where completely lossless quality is required. However, for publishing images on websites, blogs, landing pages and eCommerce stores, WebP is usually the better option because it dramatically reduces file size while maintaining excellent image quality. If your goal is faster websites, improved Core Web Vitals and reduced hosting bandwidth, WebP is generally the recommended format.
Converting PNG images to WebP does not directly increase Google rankings, but it can improve several technical factors that influence overall site quality. Smaller image files reduce loading time, improve user experience and help websites achieve better Core Web Vitals scores. Faster pages generally reduce bounce rates and create a better browsing experience, particularly on slower internet connections and mobile devices. Optimizing images is considered one of the easiest performance improvements for modern websites.
