HEIC, animated WebP input, PNG sequences and frame sequence export require Pro.
To convert a GIF to animated WebP, drop the GIF on LightBox, keep the pre-filled settings, and download — the loop, timing, and frames are preserved in a file that's typically a fraction of the size. Google's own measurements put lossy animated WebP around 64% smaller than the equivalent GIF, and real-world memes and screen recordings often shrink far more.
The size difference isn't magic — it's age. GIF is a format from 1989: a 256-color palette, heavy dithering to fake the colors it can't show, and no modern compression. Animated WebP keeps everything people actually like about GIFs (drop it in an image tag, it autoplays and loops, no player) while fixing the rest: full 24-bit color, real alpha transparency, and compression designed this century. Every current browser displays it.
That makes GIF-to-WebP the single highest-leverage swap on a slow page. If your site, docs, README, or store listing ships GIFs, converting them is usually worth seconds of work for a multi-megabyte saving per file — better Core Web Vitals, less bandwidth, same visual.
Why convert with LightBox
Same loop, a fraction of the bytes
The conversion keeps every frame and its timing, so the WebP behaves exactly like your GIF — it just weighs dramatically less. A multi-megabyte reaction GIF routinely lands under a megabyte, which is the difference between a page that drags and one that snaps in.
Full color, no more banding
GIF fakes gradients with 256 colors and dithering noise. WebP carries millions of colors, so skies, skin tones, and UI gradients come out clean. Counterintuitively, the better-looking file is also the smaller one — you upgrade quality and size in the same move.
Optimize the GIF instead, if you must
Need to stay a GIF for an app that demands one? Switch the output to Optimized GIF and LightBox rebuilds it with a tuned per-clip palette — smaller than the original while staying universally compatible. But when the target is a website, WebP wins on every axis.
