We always strive to make your sites run as quickly and smoothly as possible, both on the front end and under the hood. Our most recent improvement? All self-hosted Jetpack-connected sites who have the Photon image service activated can now enjoy seamless support for the WebP image format.
What does this mean for you and your audience? This new feature provides size reductions of up to 34 percent for served images compared to a JPEG image of an equivalent visual quality level. Your viewers will save a lot of time loading your pages — time they can better spend enjoying the content you publish.
While WebP isn’t currently supported by all browsers (see the WebP FAQ for more details), you don’t have to worry about anything. We auto-detect which browsers your readers are using to make sure they can enjoy your images in the best quality and highest speed possible.
We should note that by default, Photon is compressing the WebP images at a high quality setting. If you want to get the most out of this new feature, utilizing the quality parameter will yield the best results.
If you’d like to learn more about this fast-loading image format, check out the following links:
