WebP is no longer a new wave image file format. It’s supported by all five of the top mobile browsers including Chrome Mobile, Mobile Safari, Chromium, Samsung Browser, Facebook on Android, and more. The great news for eCommerce and B2C companies is that ImageEngine automatically reformats images to the proper file format for the fastest image delivery possible, including WebP of course!

Websites and eCommerce sites are adopting image optimization to provide superior web performance, particularly on mobile devices. Resizing, compressing, and converting images to nextgeneration formats generates images up to 80% smaller than their original size.

WebP was not always seen as the most efficient next-generation image format. Prior to Safari version 14, JPEG 2000 was the most efficient next-generation image format supported by Apple’s Safari browser. However, Safari version 14, released September 2020, started to support WebP. WebP image format was already supported by Chrome (and its Chromium derivatives), the world’s most popular mobile browser, starting back in 2014 with version 32.

[Image CDNs](https://imageengine.io/features/what-is-an-image-cdn/ “Image CDN”) automatically convert images to next-generation formats, including WebP, JP2 (JPEG 2000), and AVIF. ImageEngine will convert to images to the most efficient format supported by the device and browser. We studied millions of image format conversions performed by the ImageEngine.io [image CDN](https://imageengine.io/features/what-is-an-image-cdn/ “image CDN”).

WebP has increased by 26 percentage points from 2020 to 2021. 71% of all traffic is now delivered in WebP format. This increase is driven by Safari’s adoption of WebP in version 14 released September 2020. The remaining 13% of images using JP2 are delivered to Safari browser versions prior to 14.
