GIF images are restricted to 256 colors with limited compression, but the format is supported in all graphical web browsers and is still widely used. 

Animations can be generated ad hoc in a browser with the [[Cascading Style Sheets#CSS 3|CSS 3]] features [[CSS animations|animations]], transitions, and [[Sprite (computer graphics)#Sprites by CSS|sprites]], or also the [[JavaScript]] [[web animations API]], by specifying frames or motions of still images or rendered shapes. This can be resource-intensive, and the animation generally cannot be saved in a portable image file or posted on [[imageboards]].

[[Internet Explorer]] only supported GIF, CSS, and Flash animations.
