Convert pct to psd

What is the difference between .pct and .psd?

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.; A PSD file is an image file created by Adobe Photoshop, a professional image-editing program often used to enhance digital photos and create web graphics. It is the native format used to save files in Photoshop. PSD files may include image layers, adjustment layers, layer masks, annotations, file information, keywords, and other Photoshop-specific elements. They are commonly created and shared among graphics professionals.
