GIF File Format FAQ

What is GIF mostly used for?

GIF appears in 1 category workflows across this library and is commonly used in image pipelines.

Use the related comparison, best-format, and conversion links on this page to evaluate tradeoffs and migration paths.

What is the maximum color depth of a GIF?

GIF is limited to 256 colors (8-bit palette) per frame. Animated GIFs work around this with per-frame local palettes. For full-color images, use PNG or WEBP.

How are animated GIFs structured?

Animated GIFs contain multiple image frames with disposal methods and inter-frame delays encoded in Graphic Control Extensions. Players that ignore disposal methods produce visual artifacts on frames with transparency.

Why do GIF files get large quickly?

GIF uses LZW compression which is efficient for flat graphics but poor for photographic content. A 640×400 animated GIF with 30 frames of photographic content can easily exceed 5MB.
