Crello is a free, easy to use online design platform that is used by experienced as well as novice designers.

Crello just launched an animated design feature which allows anyone to create engaging motion graphics for social media. This platform has hundreds of animated templates that are ready to use and are fully customizable. Animated graphics can be downloaded in the mp4 format, making Crello the only web-based application to offer this feature to non-designers. Currently, the two formats for the animated templates are Universal Social Media Post and Instagram Post. There are plans to expand the formats in early 2018 to include Facebook Covers, Facebook Posts, icons, and illustrations.
