PNG is a lossless image format that supports transparency. It is ideal for graphics, logos, screenshots and images that require sharp edges or transparent backgrounds. PNG files are typically larger than JPG files. WebP is a modern image format developed by Google. It provides superior compression for both lossy and lossless images, reducing file sizes by 25-35% compared to JPG while maintaining the same quality. All modern browsers support WebP.
