Convert GIF to WebP Online

GIF is graphics interchange format. Animated WebP does everything GIF does at a fraction of the size and with 16 million colours instead of 256. Converting a GIF to WebP routinely cuts 60-80% off the file while removing the dithering and colour banding the palette forced on it.

WebP is the default currency of fast web pages — smaller than JPEG at the same visual quality, smaller than PNG while keeping transparency, and supported by every browser in use. In practice that means a page that loads faster on mobile, a better Largest Contentful Paint score, and less CDN bandwidth — for the same picture. GIF files are dramatically larger than animated WebP — often 3-5x for the same clip, so this is usually the single biggest weight saving available on a page built from them.

Going the other way costs real quality: a full-colour image squeezed into GIF's 256-colour palette will show visible banding and dithering, and GIF's 1-bit transparency turns WebP's soft alpha edges into hard jagged ones. WebP tops out at 16383 pixels on either edge, so anything larger is scaled to fit; for the vast majority of web work that ceiling is nowhere near a constraint.

WebP was released by Google in September 2010, built on the intra-frame compression of the VP8 video codec Google acquired with On2 Technologies. Lossless mode (VP8L) and alpha transparency arrived in 2011, animation in 2012. Adoption stalled for most of a decade because Safari refused to ship it, so sites had to serve fallbacks anyway. That ended in September 2020 when Apple enabled WebP in Safari 14, macOS Big Sur and iOS 14 — overnight the format became genuinely universal in browsers. Today Next.js, Cloudflare, Cloudinary, imgix, WordPress and Shopify all emit WebP by default, which is why so many images saved from the web now land on disk as a .webp file.

Animated WebP does everything GIF does and does it far better. Converting a GIF routinely cuts 60–80% off the file while lifting the 256-colour ceiling to full 24-bit colour, which removes the banding and dithering the palette forced on the original. For anything animated on a modern page, this is a straight upgrade.

The saving matters because GIFs are usually the single heaviest asset on a page that has one. A 4 MB reaction GIF at the top of an article is doing more damage to your load time than every other image combined, and it is the easiest thing on the page to fix.

Static GIFs convert just as well and end up dramatically smaller. Keep the GIF original only if you need to serve platforms with hard-coded format allowlists — some chat apps, forums and ad networks still accept nothing else.
