For Social Media Gids we use Canva to make our graphic design amazing with the drag-and-drop design tool. Canva
(with a library of more than 1 million stock photographs, graphic elements and fonts) makes it easy to make your social media icons and posts, banners and headers, newsletters, forms and business cards. 

NOTE!: If you create a lot of graphics in your business, consider getting a paid business account at Canva, where you have access to your brand colors along with your fonts, and the ability to ‘magically resize' your images.
