GIMP is a free cross-platform image editor available for GNU/Linux, OS X, Windows and more operating systems. 

This software is a free alternative to photoshop. I mostly use it to crop and resize images.

To my surprise Adobe XD is completely free to use. Adobe XD is a powerful, collaborative, easy-to-use platform that helps you and your team create designs for websites, mobile apps, voice interfaces, games, and more.

I recommend using drawing tablets (wacom products, surface book, tablet laptops, etc.)

Draw lets you produce anything from a quick sketch to a complex plan, and gives you the means to communicate with graphics and diagrams. With a maximum page size of 300cm by 300cm, Draw is a an excellent package for producing technical drawings, brochures, posters and more. Draw lets you manipulate graphical objects, group them, crop them, use objects in 3D and much more.
