Vectr is a recommended program to create and edit vector images using a simple and elegant interface that's especially designed to let any user start working in minutes.
Before beginning to use the program, you'll need a Vectr user account, which you can create in seconds with a Google or Facebook social login. Once you've gotten started you can dig in with the vectors. Or you can opt to work as a guest without creating an account, though you won't be able to save your work in the cloud.
Within seconds of starting to use Vectr you'll notice that you're dealing with a user-friendly program. Any user who's ever worked with another image-editing program won't have any problem understanding most of its controls. On the left of the interface is your list of layers and pages, and on the right your contextual tools. From the toolbar, as usual, you can create any new shape.
Vectr is a great tool for vector creation and editing with a wide variety of features inside a convenient and user-friendly interface. Once you've finished with any project, just save it in PNG format right to your hard drive.
