Each social media platform has different specifications for photos. When choosing to share to multiple platforms through Echobox, it is important to keep in mind that one post may work on one platform and fail for another.

* A small percentage of WEBP images have colour profiles that we cannot support - Echobox will not process these images to avoid our users sharing incorrectly formatted images. We advise using JPG or PNG formats wherever possible.
