Why animated WebP instead of GIF?

Animated WebP files are typically 25–50% smaller than the same content as GIF, and they support full 24-bit colour and alpha transparency. Drawback: support is more limited in older software.

Does my browser support it?

Chrome, Edge, Firefox and Safari 14+ all play animated WebP. Older email clients and some chat apps may not.

Are my images uploaded?

No. ffmpeg.wasm encodes the WebP locally; nothing leaves your device.

Animated WebP Maker — Build an Animated WebP from Images

How to make an animated WebP

Pick the image frames in playback order. Transparent PNGs preserve alpha.
Set the frame delay (100 ms ≈ 10 fps).
Set the output width and quality (80 is the sweet spot).
Press Build animated WebP. Wait for ffmpeg.wasm to finish, then download.

Common use cases

Sticker packs for chat apps that prefer WebP over GIF.
Product loops on landing pages — same motion at half the size of a GIF.
Email teaser images in newer email clients that support WebP.

Frequently asked questions

Where can I play an animated WebP?

Modern browsers, Twitter / X, Discord and most chat apps support it. macOS Preview and a few legacy email clients do not.

Is the WebP lossy?

Yes by default — quality 80 is visually clean. Set quality to 100 for near-lossless output at much larger size.

Why not just use GIF?

GIF is universal but capped at 256 colours per frame and unweildy file sizes. WebP gives full colour and alpha, typically at half the size or less.
