GIF vs. Animated WebP: What's Actually Different

Published 2026-09-29

GIF and animated WebP are both looping images made of a sequence of frames. They look similar on the surface, but they handle color very differently under the hood, which leads to real differences in file size and quality even for the same source clip.

The biggest difference: how many colors each frame can use

GIFAnimated WebP
Colors available per frameUp to 256Effectively unlimited (photographic-level color)
Smooth gradients and subtle color shiftsTend to band and look blotchyRendered smoothly
File size at the same visual qualityLargerUsually smaller — often under half the size of an equivalent-quality GIF
CompatibilityPlays almost everywhereSupported by most current browsers and apps; some older software shows only a static frame

Why colors band in a GIF

GIF is an older format limited to 256 colors per frame. A scene with subtle, continuous color shifts — a sunset with a soft gradient sky, for example — gets each pixel snapped to the nearest of those 256 colors, producing visible banding. WebP has no such limit and can render the original colors as they are.

Why GIF still gets used

  • It plays practically everywhere without exception — messengers, forums, email signatures. WebP works fine in modern environments but can show up as a static image on older software.
  • GIF is still treated as something close to a universal standard when re-sharing or re-uploading an animation to another site.

Which one to pick

SituationRecommendation
Sharing widely (messengers, forums)GIF
An animation embedded on your own blog or siteWebP (smaller at the same quality)
Scenes with smooth color transitions (sunsets, gradient backgrounds)WebP (GIF tends to band)
Not sure where it will be viewedGIF (the safest for compatibility)

How prezll handles this

The prezll GIF editor (/gif) accepts both GIF and animated WebP files as input. Output is always exported as GIF, so a very colorful source gets converted as smoothly as possible within GIF's 256-color limit. For scenes where banding is especially noticeable, lowering the compression strength and trimming the frame count is a better way to manage file size than pushing compression harder.
