Convert GIF to WebP — Free, Fast & Private
WebP can be animated, but this converter writes a still. Read that first, then decide whether it is what you want. Everything runs in your browser — nothing is uploaded.
A still, not an animated WebP
MiniPx writes one frame from an animated GIF, the first, and tells you so. It does not produce animated WebP. If you need motion, use an animation tool; if you need a lighter still or thumbnail, this is the right place.
Transparency is kept
GIF transparency (on or off per pixel) is carried into WebP alpha. The edges remain as hard as the GIF drew them. A cleaner cut-out can come from the background remover.
The 256 colours stay 256
WebP can store more colours, but the picture was reduced to 256 when it became a GIF, and that cannot be undone. GIF to PNG gives a lossless copy; GIF to AVIF goes smaller still but is opened by fewer apps.
When a WebP still helps
A WebP still is useful for a small, light replacement of a flat graphic or a thumbnail from an animation, with transparency intact. For an animation that should keep moving you need a different tool; MiniPx does not write animated WebP. The measured table below uses real GIFs.
Check the WebP against the GIF before you save
The result card shows the GIF size, the WebP size and the output dimensions, and the notice about animation if the GIF had several frames. Batches download as a ZIP.
Support
Browsers display WebP from Safari 14. Every other WebP direction is on the WebP converter.

Measured 2026-10-07 in Chromium 145.0.7632.6 by running this page's converter with its default setting (WebP) on each file. The photos and scans are CC0 or public-domain files from Wikimedia Commons; the screen-recording GIF is drawn by the measuring script; the photo GIF pans across the CC0 phone photo; the spinner GIF is drawn by the measuring script on a transparent background. Sizes are shown as the tool shows them (1 KB = 1,024 bytes).
