JPG is the most widely used image format for photographs and web images. It uses lossy compression to significantly reduce file sizes while maintaining acceptable visual quality. Nearly all devices and applications support JPG natively. 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.
