WebP files: what they are and how to open or convert them

WebP is Google's modern web image format. It supports both lossy and lossless compression plus transparency, and typically comes out 25-35% smaller than an equivalent JPG or PNG. Every current browser displays it, but some older desktop apps and upload forms still reject it.

What is a WebP file?

WebP is an image format Google released in 2010 to make web pages lighter. It supports lossy compression like JPG, lossless compression like PNG, transparency, and animation, and typically produces files 25 to 35 percent smaller than the equivalent JPG or PNG at the same visual quality. Every modern browser has supported it since 2020, so a large share of the images you save from websites now come down as .webp.

How to open a WebP file

Any current browser displays WebP, and Windows 11 Photos, macOS Preview (since Big Sur), and recent Android and iOS versions open it too. Where it fails is older desktop software: Photoshop needed a plugin until 2022, many upload forms only accept JPG or PNG, and Microsoft Office and email clients are inconsistent.

When something refuses a WebP, convert it to PNG (lossless, keeps transparency) or JPG (smaller, for photos). Both converters run in your browser and take a batch of files at once.

When to use WebP

Use it for images on websites: it is the format Google PageSpeed asks for, and it cuts page weight without visible loss. Keep a PNG or JPG master for editing and for anything that has to open in older tools. Animated WebP is a much smaller alternative to GIF, but GIF still wins on compatibility in chat apps and forums.

Frequently asked questions

Is WebP lossy or lossless?

Either. A WebP file can use lossy compression for photos or lossless compression for graphics and screenshots; the encoder decides per file.

Why do images download as WebP?

Because the website serves WebP to browsers that support it. Right-click and copy the image, or save it and convert it to PNG or JPG here.

Does WebP support transparency?

Yes, in both lossy and lossless modes, which is one advantage over JPG.
