Which file types are the most common graphic formats found on the World Wide Web?

JPEG (Joint Photographic Experts Group) and GIF (Graphics Interchange Format) are among the most widely used graphic formats on the World Wide Web due to their specific advantages in web usage. JPEG is particularly suited for photographs and images with complex color variations because it compresses file size without significantly compromising quality. This makes it ideal for faster loading times on web pages while maintaining acceptable visual fidelity. GIF, on the other hand, supports animations and is known for its lossless compression, which allows for clear images even with a limited color palette, making it popular for simple graphics, logos, and animations.

Other formats listed, such as PNG and BMP, are less common in web use. PNG is indeed popular for its ability to handle transparency but hasn't reached the same level of widespread adoption for web photographs as JPEG. BMP is rarely used online due to its large file size and lack of compression. Additionally, formats like TIF and PSD are primarily used for professional graphic work and not optimized for web use. Formats like SVG and WEBP have gained attention for specific functions but have not yet achieved the ubiquity of GIF and JPEG on the web, reinforcing why JPEG and GIF are the most commonly found graphic formats online.
