What is a common file format used for web graphics?

Choosing the JPEG format as a common file format for web graphics is accurate due to its widespread use, particularly for photographs and images that require a wide range of colors. JPEG (Joint Photographic Experts Group) is particularly efficient in compressing image data without significant loss of quality, making it an ideal choice for web use where loading speed and bandwidth are critical considerations.

The JPEG format supports a vast color palette and provides the ability to adjust quality settings, allowing for high compression rates that maintain acceptable visual quality. This balance is crucial for web graphics, especially when dealing with large images or limited bandwidth scenarios.

In contrast, formats like PNG are primarily used for images that require transparency or those needing lossless compression, while GIF is popular for simple animations and images with limited colors. The BMP format, while capable of high-quality images, is not commonly used on the web due to its large file size and lack of compression, making it inefficient for online graphics where loading speed is essential.
