PSF is a file extension that is primarily associated with Adobe Photoshop’s proof settings file. PSF stands for “palette storage format.”

A PSF file stores color settings that are used to ensure that an image preview will display properly for an accurate view of the finished product.

PSF files open in Photoshop. A PSF file can also be converted to another image type, such as JPG, to open in other programs.

The PSF file extension is also used for a Postscript printer font file format.
