Technical Specifications & Codec Breakdown
Why GIF is Obsolete for Web Animation
GIF was created in 1987 and is limited to 256 colors, causing graininess and massive file sizes. Converting a 15 MB looping GIF to Animated WebP or a muted MP4 video shrinks the file to ~1.5 MB with full 24-bit truecolor fidelity and alpha transparency.
When to Pick Animated WebP vs. Looping Video
Animated WebP is ideal for UI micro-interactions and stickers requiring alpha transparency. For long video clips, HTML5 muted looping video (MP4/WebM) provides hardware acceleration and saves mobile battery life.
