MAC to CAL Conversion: FAQ

What are MAC files?

The MAC extension stands for bitmap images associated with the MacPaint program developed by Apple MacIntosh. MAC images only support a monochrome (black and white) color rendering, are not scalable and have a modest resolution of 75 dpi. However, they are quick to download and decompress. MAC files can also be found under the PNTG extension on Mac computers and they are frequently used for clip art or monochrome graphics.

What are CAL files?
