(Photoshop Document) format stores an image with support for most imaging options available in Photoshop. These include layers with masks, color spaces
, ICC profiles
, transparency, text, alpha channels and spot colors
, clipping paths
, and duotone settings. This is in contrast to many other file formats (e.g. .EPS or .GIF) that restrict content to provide streamlined, predictable functionality. Photoshop's popularity means that the .PSD format is widely used, and it is supported to some extent by most competing software.
