Supplier Sent WebP Images? Convert Them to JPG

Your supplier emails over the product photos you've been waiting for, you double-click the first one — and nothing opens, or your photo editor throws an error. The files end in .webp, a format your tools and your marketplace may not accept. You can't edit them, you can't upload some of them, and you're stuck. The fix is to batch-convert the whole lot to JPG.

How to convert a supplier's WebP photos to JPG

QuickWand's free WebP to JPG converter runs in your browser, so even a big batch of supplier photos never leaves your computer.

1. Open the WebP to JPG converter.
2. Drag the entire folder of .webp files into the drop zone, or click to browse and select them all.
3. Choose JPG as the output (or PNG if a photo needs a transparent background) and set quality around 90%.
4. Click Convert, then click Download all (.zip) to grab every converted photo in one file.

Now you can open them in any editor, retouch them, and upload them to your store.

Why do suppliers keep sending WebP?

WebP is an image format Google introduced to make web pages load faster — it produces smaller files than JPG or PNG at similar quality. Over the past few years it has become the default behind the scenes: when a supplier saves an image from their own website, a wholesale catalog, or a modern design tool, the file that lands on their computer is often a .webp rather than a JPG. They forward exactly what they got, and you inherit the format problem.

The trouble is that WebP support outside the browser is patchy. Many desktop photo editors, older versions of Photoshop, print services, and some marketplace upload forms still don't accept it. Amazon, for instance, does not support WebP for product images at all, and Etsy doesn't list it among accepted formats — so converting to JPG is the safe move.

A note on transparency

WebP can store transparency, just like PNG. If one of the supplier photos has a transparent background and you convert it to JPG, those transparent areas will be filled with a solid background, because JPG cannot keep transparency. If you need the cut-out to stay see-through, choose PNG as the output format instead.
