What is WebP?
WebP is an image format created by Google for the web. It supports both lossy compression (like JPG) and lossless compression with transparency (like PNG), and at similar quality it is usually 25–35% smaller than JPG and much smaller than PNG. Every modern browser, including Chrome, Safari, Firefox and Edge, can display it.
Why use WebP on a website?
Images are often the heaviest part of a web page. Smaller images load faster, use less mobile data and help your pages pass Google's Core Web Vitals checks, which can support better search rankings. Converting your photos and graphics to WebP is one of the easiest speed wins for a blog or online shop.
When to convert WebP back to JPG or PNG
Some older apps, printing services and upload forms still don't accept WebP. If an image you downloaded won't open or upload, convert it to JPG (for photos) or PNG (for graphics with transparency) here.
Recommended settings
| Image | Format | Quality |
|---|---|---|
| Photo for a website | WebP | 75–80% |
| Logo or graphic with transparency | WebP | 90% or more |
| Photo for an app that doesn't accept WebP | JPG | 85–90% |
| Screenshot that must stay pixel-perfect | PNG | – |
Why does my browser say it can't create WebP?
Creating WebP depends on your browser. Chrome, Edge and Firefox can; some versions of Safari can only display WebP, not save it. If that happens, try another browser.
