Free converter
JPG to WEBP
Convert JPG photos to WEBP, which is typically a quarter to a third smaller at matching quality. Ideal for speeding up a website. Because the conversion runs in your browser rather than on a server, your file is never uploaded, never stored and never seen by anyone else.
Drop your file to start.
The converter needs JavaScript, because the conversion itself runs on your own device rather than on a server. Enable JavaScript to load it.
Why WEBP is worth the switch
WEBP generally produces files 25–35% smaller than JPG at visually equivalent quality, and every current browser supports it. On an image-heavy page that is one of the cheapest Largest Contentful Paint improvements available, which matters both for visitors and for search rankings.
Serving WEBP safely
If you still need to support very old clients, serve WEBP
through a <picture> element with a JPG fallback. Modern browsers take the WEBP; anything
else falls back gracefully.

Frequently asked questions
How much smaller will the WEBP be?
Usually 25–35% smaller than the equivalent JPG at the same visual quality, though it varies with the image content.
Do all browsers support WEBP?
Every current version of Chrome, Edge, Firefox, Safari and Opera displays WEBP. Some older desktop applications still do not.
Is WEBP lossy or lossless?
It supports both. The conversion here is lossy, controlled by the quality slider, which is what makes the size saving possible.
Will image quality drop?
At the default setting the difference is not visible in normal viewing. Raise the quality slider if you need a closer match.
