The PICT file format is a legacy graphics standard developed by Apple Computer for the original Macintosh operating systems. It serves as the primary metafile format for the QuickDraw imaging model, supporting both bitmap images and vector graphics within early desktop publishing applications. Although it was the default graphics format for early versions of Mac OS, it is now considered obsolete and has been replaced by modern standards such as PDF.
