PaintShop Pro

PaintShop Pro has been a fairly popular commercial graphic program since the 1990s. Originally released as "Paint Shop" by JASC Software, it soon became PaintShop Pro (with "PaintShop" officially written as one CamelCased word, though it's often written unofficially as two words). In 2004, it was acquired by Corel.

Many standard graphic formats including GIF, JPEG, and PNG are supported, but there is also a native PaintShop Pro format. These files, stored in a format allowing the preservation of the distinct layers of a PSP image for editing, are normally found with the extension .psp (or sometimes .pspi in later versions), but some other specialized image types with other extensions are also used.
