WEBP Support

We are pleased to announce that CourseLit now supports WEBP by default. This means that every image you upload to CourseLit will get auto-converted to its WEBP counterpart.

CourseLit generates thumbnails for the image and video resources that you upload. With the new release, the thumbnails will also be in the WEBP format.

IMPORTANT: Any existing resource and its related thumbnail will not be auto-converted to WEBP. You have to do it manually.


Serving images in next-gen formats is something what Google’s Pagespeed Insights tool recommends for faster and efficient loading of images on websites. Hence, we worked hard to bring WEBP support to CourseLit. CourseLit now passes the aforementioned test.
