[[2D computer graphics|2D animation]] figures are created or edited on the computer using 2D [[Raster graphics|bitmap graphics]] and 2D [[vector graphics]].{{sfn|Masson|2007|p=165}} This includes automated computerized versions of traditional animation techniques, [[Interpolation|interpolated]] [[morphing]],{{sfn|Sito|2013|pp=32, 70, 132}} [[onion skinning]]{{sfn|Priebe|2006|pp=71–72}} and interpolated rotoscoping. 2D animation has many applications, including After Effects Animation, [[Scanimate|analog computer animation]], [[Flash animation]], and [[PowerPoint animation]]. [[Cinemagraph]]s are [[Still life photography|still photographs]] in the form of an [[animated GIF]] file of which part is animated.{{sfn|White|2006|p=392}}

Final line [[advection]] animation is a technique used in 2D animation,{{sfn|Lowe|Schnotz|2008|pp=246–47}} to give artists and animators more influence and control over the final product as everything is done within the same department.{{sfn|Masson|2007|pp=127–28}} Speaking about using this approach in ''[[Paperman]]'', John Kahrs said that "Our animators can change things, actually erase away the CG underlayer if they want, and change the profile of the arm."{{sfn|Beck|2012}}

When working with game animations, [[Skeletal animation|skeletal]] 2D animations are commonly created using tools like Spine, DragonBones, Blender COA Tools, Rive, and the built-in Unity editor. The primary benefit of this approach is the ability to reuse images, which reduces the amount of graphics stored in RAM. This principle of maximizing resource efficiency means that by reusing existing elements, you can enhance the visual appeal of animations without needing to create additional graphics.<ref>{{Cite web |title=Spine Animation Optimization: Save Your Nerves and Time by Avoiding Bugs |url=https://astanahub.com/en/blog/optimizatsiia-spine-animatsii-sokhraniaem-nervy-i-vremia-ne-dopuskaia-bagov |access-date=2024-09-23 |website=astanahub.com |language=en}}</ref>
