Converting JPG to WebP free happens the moment your files hit this page. Each JPG becomes a WebP that looks the same and weighs noticeably less, and your images stay completely private. No upload, no file cap, no signup.
Why webmasters bother with WebP
Image weight is usually the biggest chunk of a page's download, and page speed feeds directly into Core Web Vitals, search ranking, and checkout conversion. WebP compresses photos about 25-30% better than JPG at the same visual quality, so swapping product shots and blog images to WebP is one of the cheapest speed wins there is. Every browser that matters has supported it since 2020.
Pick a quality, or don't
The default is Maximum (0.95): visually identical to the original, still smaller than the JPG. Balanced is the sweet spot for most product and blog images. Smaller squeezes hardest for thumbnails and image-heavy grids where nobody's pixel-peeping. When in doubt, leave it on Maximum.
FAQ
Will WebP work everywhere?
In browsers, yes: Chrome, Safari, Firefox, and Edge have all supported it for years. Some desktop apps and older email clients still don't open WebP, so keep it for the web and keep JPGs for everything else.
How much smaller will my files get?
Typically 25-30% at the same visible quality, sometimes more. It depends on the photo: busy detailed shots compress less, clean product shots on plain backgrounds compress a lot.
Are my images private?
Completely. Each image converts on the spot and saves straight to your Downloads folder. Your images are never uploaded, stored, or seen by anyone. Skeptical? Here's how to check.
