Convert GIF to WebP

Convert GIF to WebP online, free and 100% in your browser. No upload, no signup. All the work happens on your device, so files can be as large as it can handle.

How to convert an image

  1. Drop or pick your GIF file, or paste it with Ctrl/⌘+V.
  2. WebP is already selected as the target; tune the quality slider if you like (default 80).
  3. Convert, compare the before/after, and save. Animated GIFs are split into one WebP image per frame and packed as a ZIP.

Why convert to this format?

GIF is a 256-color format best known for simple animations, but heavy and low-fidelity for photos. WebP is a modern web format that is typically 25-35% smaller than JPG or PNG at the same quality, with transparency.

OptImg runs the same high-quality engines desktop tools use, so you get desktop-grade WebP output at a sensible default (quality 80), adjustable at any time, without ever uploading your image.

Your GIF is decoded, re-encoded to WebP and handed straight back, ready to save, all in an instant on your device: no server sees a single byte, which is why there's no queue and files can be as large as your device can handle.

Frequently asked questions

Is my GIF uploaded to a server?
The GIF-to-WebP conversion runs at native speed entirely in your browser: nothing is uploaded, your file never leaves your device, there is no queue, and no size limit beyond your device's memory.
What happens to an animated GIF?
Each frame is extracted and converted to a separate WebP image, then delivered together as a ZIP, the classic GIF-to-WebP behavior. Animated WebP output isn't supported yet.
Will converting GIF to WebP lose quality?
WebP is lossy, tuned to a visually transparent default (quality 80) that you can raise or lower with the slider. If the conversion can't produce a smaller file than your original, we hand the original back instead.
Is the GIF to WebP converter free?
Yes: completely free, with no signup, no watermark and no cap on how many files you convert. There is nothing to install; it runs in your browser.
