Imagine a Magic Shrinking Machine for Images
You have a photo that is 1MB. You run it through the magic machine. It comes out looking exactly the same — but now it is only 650KB. That machine is called WebP.
WebP is an image format created by Google. It was designed for one purpose: to make images on the internet load faster without looking worse. It does this by using smarter compression than older formats like JPG and PNG.
How Much Smaller Does WebP Make Images?
| Original Format | Original Size | WebP Size | Saved |
|---|---|---|---|
| JPG photo | 500 KB | 330 KB | 34% |
| PNG logo | 200 KB | 130 KB | 35% |
| JPG product photo | 1.2 MB | 820 KB | 32% |
On average, WebP images are about 25 to 35% smaller than JPG at the same visual quality. For a website with 50 images, that can mean several megabytes less data for every visitor — which makes pages load much faster.
Does WebP Work in All Browsers?
Yes. As of 2024, WebP works in every major browser — Chrome, Firefox, Safari, Edge, and Opera. Over 97% of all internet users can view WebP images. This was not always true (Safari only added support in 2020), but it is not a concern anymore.
Does WebP Support Transparency?
Yes — and this is one big advantage over JPG. WebP can do everything JPG does AND everything PNG does:
Who Should Use WebP?
If you are still using JPG for every image on your website, switching to WebP is one of the easiest performance improvements you can make.
