A lot of designers without any research buy most popular tools such as Photoshop and other Adobe tools, although never use all their capabilities. It is important to know that there are free applications that can be used for web design and which do not fall behind for expensive professional tools. Before you spend your money on a set of applications that never fully exploited, determine your requirements and search the Internet for available solutions.
My choice
Here I will mention only those applications that I use in my work, it does not mean that there are other alternatives that you can find a simple internet search. In my work I have tried many solutions but the following applications have proven to be the best.

It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc. GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted. GIMP is written and developed under X11 on UNIX platforms. But basically the same code also runs on MS Windows and Mac OS X.

Geany is known to run under Linux, FreeBSD, NetBSD, OpenBSD, MacOS X, AIX v5.3, Solaris Express and Windows. More generally, it should run on every platform, which is supported by the GTK libraries. Only the Windows port of Geany is missing some features.
