What Is WebP Animation Creator?

An animated WebP creator that combines image frames into a single animated WebP file. WebP animations offer better compression than GIF while supporting full color and transparency. The tool uses the browser's native WebP encoder for each frame, then assembles them into the RIFF-based animated WebP container format with VP8X extended header, ANIM chunk, and per-frame ANMF chunks.

Why Use WebP Animation Creator?

Superior compression compared to GIF and APNG
Full 24-bit color with alpha transparency
Widely supported in modern browsers
Smaller file sizes for web performance

Common Use Cases

Web Performance

Replace GIFs with smaller animated WebP for faster loading.

Banners

Create lightweight animated web banners.

Stickers

Animated stickers with transparency for messaging apps.

Product Showcases

Smooth animated product previews with small file size.

Technical Guide

Each frame is rendered to canvas and encoded to WebP via canvas.toBlob. The animated WebP is built by constructing a RIFF container: VP8X chunk with animation flag, ANIM chunk for global settings, and ANMF chunks per frame containing offset, dimensions, delay, and the VP8/VP8L payload extracted from each individual WebP. The VP8 payload is located by parsing the RIFF structure of each frame.
