What this does
Converts WebP images to JPG with a quality slider, fully in your browser.
Handy for the long tail of software and services that still won't take a
.webp upload.
Where does WebP still get rejected?
Mostly anywhere images get submitted rather than displayed: marketplace listings, classifieds, visa and ID portals, CMS media libraries with strict allow-lists, email clients that won't inline it, and older corporate tooling. JPG has been the lingua franca of photos for 30 years — converting to it makes the problem disappear.
JPG or PNG — which should I convert WebP into?
- JPG (this page) — photographs and screenshots headed for an upload form. Small files, universal support, no transparency.
- PNG — logos, graphics, or anything with a transparent background; also the right choice when you'll edit the image further, since PNG is lossless.
What quality should I export at?
The default 92 is effectively visually lossless. Since the WebP was probably already lossy-compressed once, avoid going below ~80 — stacking two rounds of heavy compression is where artifacts start to show, especially around text and sharp edges.
What happens to transparent backgrounds?
JPG has no alpha channel, so transparent regions get flattened in conversion. If the WebP is a cutout or sticker, use WebP to PNG instead to keep the transparency.
Is my data private?
Yes — decoding and encoding both happen inside your browser tab. No image ever touches a server, and there's nothing to delete afterwards.
