Color bitmap image saved in the native Paint Shop Pro format; may include layers, guides, vector paths, metadata, and other objects within the image file.

Paint Shop Pro, often referred to as "PSP," is a similar program to Adobe Photoshop (which uses the .PSD format). It includes many features that Photoshop does, but is offered at a lower price point. Therefore, it is often compared to Adobe Photoshop Elements.

Paint Shop Pro was developed by Jasc Software for many years until it was acquired by Corel in 2004. There is no Macintosh version of Paint Shop Pro.
