I have a designer's requirement for both SharePoint 2013 and SharePoint online to allow him to display images in webp format.

Does anyone know how to achieve this?

Thank you

    try it and then let us know. Put a webp in a document library and then reference it in a script editor. – Derek Gusoff Aug 2 '19 at 18:47

SharePoint 2013/Online does not recognize .webp as an image file. As a result, none of the out-of-thebox image-related SharePoint features will work. This includes:

  • image webparts,
  • image rendition
  • Image sliders
  • Image size (width/height) population in the Assets library,
  • etc.

At the same time SharePoint will still serve .webp files as any other file that is not blocked by at the tenant level. Once Web server (SharePoint) serves this file - any modern browser will handle it automatically. For example, if you create a script editor webpart with this content:

<img src="https://zergs.sharepoint.com/Shared%20Documents/2.webp" width="400px" />

You will see that it's rendered properly:
