The file format that is limited to 256 colors is the GIF format. This limitation makes GIF particularly effective for illustrations, especially those that require solid colors and simple graphics, such as logos, icons, and animations. The restricted color palette allows for compression that maintains a small file size while still preserving image quality, which is beneficial for web use.

GIF uses a lossless compression technique, meaning that it does not lose any quality when the file is saved and saved again, which is essential for preserving the integrity of illustrations. Additionally, GIF supports transparency, making it a popular choice for images that need to blend into web backgrounds seamlessly. These features contribute to its effectiveness for specific types of graphics, setting it apart from other formats that may not have the same restrictions on color variability or optimization for web display.
