Since WhatsApp is making efforts to expand the business use, this new update can facilitate more useful options for the business users. Currently, Twitter launched a similar release of bigger images and videos rather than crop-to-fit images.

The main purpose of rolling out this feature is to make sure that it is easier to maximize your focus on the multimedia content shared and also that the users are seeing more of what you are trying to share. Again, this is not one of the major tweaks but is surely a useful one that most of the users will love.
