Why Animated GIFs are Heavy and How to Fix Them
GIF files do not use modern video codecs; instead, they store every single animation frame as an individual image, which makes them extremely heavy. Compressing a GIF correctly requires specialized pixel-differencing algorithms that only update changing areas between frames, keeping files small and fast to load.
