Before beginning to use the program, you need a Vectr user account, which you can create in seconds by using your Google or Facebook account. Once you have an account, you can start working with vectors. You can also work as a guest without creating an account, but 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. To the left of the interface, you have the list of layers and pages, while on the right you can find the contextual tools. From the toolbar, as usual, you can create any new element.
Vectr is a great tool for creating and editing vectors that presents a wide variety of features included in a convenient and user-friendly interface. Once you've finished with any project, you just have to save it in PNG format on your hard drive.
