The WebP format: what it is and how to open .webp

Saved an image from the web and got a .webp file that won't open in your usual editor? Let's see what it is and what to do.

What WebP is

WebP is an image format by Google built for the web. It gives smaller files than JPG and PNG at comparable quality and supports transparency and animation. That's why sites increasingly serve images as WebP.

Why .webp won't open

Browsers display WebP fine, but many photo editors, messengers and older programs don't, because the format is too new for them. The file is fine — the program just lacks WebP support.

How to open: convert to JPG or PNG

Conversion takes seconds with no installs. And the other way around: convert your PNG/JPG to WebP to speed up your own website.

Frequently asked questions

Is transparency kept in WebP → PNG?

Yes, a transparent WebP background carries over to PNG correctly. Converting to JPG replaces transparency with a background, since JPG doesn't support it.

Is WebP better than JPG and PNG?

For the web, usually yes — it's smaller. But for editing and maximum compatibility with older software, PNG or JPG are handier.
