I like the templates that are easy to edit, the variety of banner sizes and access to Unsplash, Pixabay and Pexels video galleries. There is also an ability to upload your own pictures. The app is also responsive.

I can create an animated ad within 5-10 minutes for a car dealerships or my agency clients. I have no experience with graphic design, but BannerBoo makes it easy for someone like me with no design experience to create animated graphics. High five!

Very easy to create html5 banners in all sizes.
