The Apple QuickDraw Picture (PICT1) was developed by Apple, which created file format and 72 programs to work with them.
PICT1 files are supported by Mac OS and Windows. To open a PICT1 file, you can choose from 2 programs such as QuickDraw 3D and TreeView.
How to open a PICT1 file?
If you cannot open a PICT1 file, it is most often due to missing software. Select a program from the list according to your operating system. Then go to the official website of the program developer, download it, and install it on your device.
