PNG vs JPG vs WebP: Which Image Format Should You Choose?
A definitive comparison guide to the web’s three dominant image formats: file size, transparency support, browser compatibility, and best use cases.
Choosing the right format before publishing an image can save megabytes of bandwidth and significantly boost your Core Web Vitals score. Let’s break down the advantages and disadvantages of each.
JPEG (or JPG) has been the universal standard for over thirty years. It excels at complex, colorful scenes such as landscapes, portraits, and product photography. However, JPEG does not support transparent backgrounds and can produce visible ringing artifacts around sharp text and vector logos.
PNG is a lossless format engineered for precision. It is the gold standard for screenshots, diagrams, software UI icons, and anything requiring alpha channel transparency. Its only drawback is that full-color photography saved as PNG can be four to ten times larger than a comparable JPEG.
WebP, developed by Google, bridges the best of both worlds. WebP supports both lossy compression (like JPG) and lossless transparency (like PNG), while producing files that are consistently 25% to 35% smaller than traditional formats. Today, WebP is supported by virtually 100% of modern browsers, making it our top recommendation for web projects.
