What is an .PCT file?

.PCT is Picture File

A PCT file is an image saved in the Macintosh PICT format, which was developed by Apple in 1984 for storing images using Apple QuickDraw technology. It contains image data in one of two formats, PICT 1, the original format that stores 8 colors, or PICT 2, a newer format that allows thousands of colors (24 and 32-bit images). PCT files support both raster and vector images.

While PICT images most commonly use the .PICT file extension on Macintosh computers, they typically are seen with a ".pct" extension in Windows. The PICT format has largely been deprecated to the more flexible .PDF format in Mac OS X.
