What Is a WEBP File (and How Do You Open It)?

You right-clicked an image, saved it, and ended up with a file ending in .webp that your usual programs won’t open. You’re not doing anything wrong — WEBP is a newer web format, and not every app has caught up. Here’s what it is and how to turn it into something universal.

What is WEBP?

WEBP (pronounced “weppy”) is an image format created by Google to make web pages faster. It can compress photos noticeably smaller than JPG and graphics smaller than PNG, while also supporting transparency and animation. That’s why so many websites now serve images as WEBP — pages load quicker and use less data.

So why is it annoying?

Because the format that’s great on the web isn’t always welcome on your computer. Older photo viewers, some editors, and a few upload forms still don’t accept WEBP. When you need to use that image somewhere else, the simplest fix is to convert it to a format everything understands.

How to convert WEBP to JPG or PNG

Pick based on what you need: JPG for the widest compatibility (photos, uploads, sharing), or PNG if the image has a transparent background you want to keep. Both conversions run entirely in your browser — your image is never uploaded.

1. 1Open the converter for the format you want.
2. 2Drop in your .webp file.
3. 3Download a standard JPG or PNG.

Need to preserve transparency instead? Use the WEBP to PNG converter.

Should you keep WEBP or convert it?

If you run a website and want it fast, WEBP is excellent — keep it. If you just need to view, edit, or upload an image somewhere that won’t accept it, convert it to JPG or PNG and move on.

Frequently asked questions

Is WEBP better than JPG?

For websites, usually yes — similar quality at a smaller size. For everyday compatibility on your computer, JPG is still the safer bet.

Will converting WEBP to JPG lose quality?

Any conversion between compressed formats can lose a little detail, but at normal quality it’s not noticeable for typical images.

How do I open WEBP on Windows or Mac?

Modern browsers open WEBP fine — you can drag the file into a browser tab. To use it elsewhere, convert it to JPG or PNG first.
