Which format is considered an open standard for Web images, facilitating compression and animation?

The correct answer is that GIF (Graphics Interchange Format) is the format considered an open standard for web images that facilitates compression and animation.

GIF is widely used for its ability to support animations by allowing multiple frames within a single file, which creates the animated effect. This capability makes GIF particularly popular for simple animations, such as looping graphics or short, engaging visual content on websites. As an open standard, GIF is accessible and usable across different platforms and applications without restrictions, making it a versatile choice for web developers looking to include animated images in their projects.

JPEG is primarily used for static images with complex color gradients and is not capable of animation. PNG is a great format for high-quality images with transparency but does not support animation. Scalable Vector Graphics (SVG) is a vector format that supports animations and can scale infinitely without losing quality, but it primarily deals with vectors rather than raster graphics. Thus, in the context of web images that emphasize both compression and animation, GIF is the valid option.
