Creates WebP versions for new JPEG image uploads if supported by the server.
This plugin adds WebP support for media uploads within the WordPress application. WebP images will be generated only for new uploads, pre-existing imagery will not be converted to WebP format. By default, WebP images will only be generated for JPEG uploads, only the original uploaded file will still exist as a JPEG image. All generated image sizes will exist as WebP only. If you wish to change this behaviour, there is a checkbox in Settings > Media that – when checked – will alter the behaviour of this plugin to generate both JPEG and WebP images for every sub-size (noting again that this will only affect newly uploaded images, i.e. after making said change).
This plugin was formerly known as WebP Uploads.

I’ve activated the Modern Image Formats plugin, but WebP images are not always generated when I upload a JPEG image. Why?
There are two primary reasons that a WebP image may not be generated:
- The Modern Image Formats plugin has identified that the WebP version of the uploaded JPEG image would have a larger file size than the original JPEG image, so it does not generate the WebP version.
- The JPEG image was not uploaded to the Media Library. At this time, WebP versions are only generated for images to the Media Library. WebP versions are not generated for JPEG images that are added to your site in other ways, such as in a template file or the Customizer.
With the Modern Image Formats plugin activated, will the plugin generate JPEG and WebP versions of every image that I upload?
By default, the Modern Image Formats plugin will only generate WebP versions of the images that you upload. If you wish to have both WebP and JPEG versions generated, you can navigate to Settings > Media and enable the Generate JPEG files in addition to WebP option.
