Convert pct to sk1

What is the difference between .pct and .sk1?

Description: 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.; An SK1 vector graphic file is a file format primarily used by the sK1 illustration program, which focuses on providing professional-quality design features for prepress processing. Unlike other vector formats, the SK1 file format is unique for its support of CMYK color, which is crucial for color accuracy in printing. It also includes advanced features such as color profiles and spot colors, making it particularly suitable for tasks that require precise color matching and high-quality print outputs.
