File Format File
Common? No
File Description Image file that uses the Macintosh PICT format; developed in 1984 by Apple for storing images on Macintosh computers and used Apple QuickDraw technology; two versions of the PICT format are available: PICT 1 - the original format that only allowed for 8 colors, and PICT 2 - a newer PICT format that can store thousands of colors (24 and 32-bit images).

PICT images often use the .PICT file extension on Macintosh computers, but typically use the ".pct" extension in Windows; the PICT format has largely been replaced by the more flexible .PDF format in Mac OS X.
Program(s) that open pct files Mac: Apple Preview; Adobe Photoshop; Any image viewer with PICT support
