What Is a WebP File?


WebP is a new image file created by Google. Unlike the traditional formats such as JPG, PNG, and GIF, WebP provides you with high-quality images, but with much smaller file sizes than traditional formats allow.

You can save WebP files with either lossless or “lossy” compression. This means you can either compress images without losing data or with losing only non-essential information. Google’s developers have suggested that lossless WebP images can be up to 26% smaller than PNGs.

The WebP format is good for its small size, but when working on Photoshop you won’t be able to open files with the .webp extension — and you’ll be shown the above error message if you attempt to.

How to Open a WebP File
