Canva

Canva is a graphic-design tool website, founded in 2012. It uses a drag-and-drop format and provides access to over a million photographs, graphics, and fonts. It is used by non-designers as well as professionals. The tools can be used for both web and print media design and graphics.

Also, Canva allows all members of the classroom community – students and teachers – to create professional, eye-catching graphics that enhance any lesson plan or project. 

I've prepared an infographic using Canva to help my students to improve their writing skills. Below you can see it.
