Convert GIF to WebP

No — that is the whole reason I built this. The conversion runs in your browser using WebAssembly, so your files never leave your device; there is no server in the loop at all. It also means the tool keeps working offline once the page has loaded, and there is no file size limit beyond your device’s memory.

The output is a still image of the first frame — static formats cannot hold an animation, and I would rather say that plainly than surprise you. If you need the motion preserved, you want a video format (MP4/WebM), which is on my roadmap.

For still images, expect 50–80% savings — GIF’s LZW compression predates the web itself, and its 256-color limit forces dithering that wastes further bytes. WebP compresses the same frame with three decades of newer technique.

Yes, and it actually gets better: GIF transparency is all-or-nothing per pixel, which causes those jagged white edges on dark backgrounds. WebP supports full 8-bit alpha, so the converted still keeps the transparency GIF had — and any future edits can smooth it properly.

Because it fixes all three of GIF’s 1987 limits at once: 16 million colors instead of 256, smooth 8-bit transparency instead of jagged cutouts, and compression that lands 50–80% smaller on the same frame. Even GIF’s party trick, animation, exists in WebP — though this tool converts stills. For anything shown on a website, the only reason left to keep GIF is compatibility with tools that predate 2010.

The animated ones should become video, not WebP stills — an MP4 of the same clip is usually about 90% smaller than the GIF and keeps the motion, which this converter deliberately does not. Convert to WebP when the frame itself is the content: thumbnails, poster images, decorative graphics. And if a legacy CMS or email template must open the result, GIF to PNG is the safer, universally supported still.
