Question 1

What is an animated WEBP?

Accepted Answer

Animated WEBP is a modern image format that plays a sequence of frames like a GIF, but with much better compression and full alpha transparency. Files are typically 25–50% smaller than the equivalent GIF at comparable quality, and all major browsers (Chrome, Firefox, Safari, Edge) display them natively.

Question 2

What can I drop into the editor?

Accepted Answer

Drop any combination of GIFs, animated WebPs, short videos (MP4, WebM, MOV), and still images (PNG, JPEG, WebP). Animated inputs are exploded into their individual frames; still images each become a single 100ms frame. You can mix and match — for example, drop a GIF and a few PNGs to extend the animation.

Question 3

Why use WEBP over GIF?

Accepted Answer

GIFs are limited to 256 colors per frame and use an outdated compression scheme. Animated WEBP supports full 24-bit color and alpha transparency, and is typically a fraction of the size at the same visual quality. The downside: very old browsers and a few legacy chat clients still don't support animated WEBP, while GIF is universal.

Question 4

What does frame skipping do?

Accepted Answer

Frame skipping drops a fraction of input frames (e.g. 0.5 = drop every other frame) and adds the skipped duration to the surrounding frames so timing stays correct. It's a fast way to shrink the output file. Use it together with the animation speed control to fine-tune motion.

Question 5

Why are videos only supported in some browsers?

Accepted Answer

Video frame extraction relies on the MediaStreamTrackProcessor API, which is currently only implemented in Chromium-based browsers (Chrome, Edge, Opera, Brave). GIFs, animated WEBPs, and still images work in every modern browser.

Question 6

Is anything uploaded to a server?

Accepted Answer

Nothing. The encoder runs entirely in your browser via WebAssembly (libwebp's webpmux compiled to WASM). Frames never leave your device. The page works offline once it has loaded.

Question 7

What's the recommended dimension and quality?

Accepted Answer

For most chat and social use, 320–512 px on the longest side at quality 70–80 produces small, sharp animated WEBPs. Increase quality to 95+ for archival or print-quality work. Use the color-limit toggle to further shrink palette-heavy animations like screen recordings or pixel art.
