JJ to PSD Conversion: FAQ

What are JJ files?

JJ is a compressed image format associated with Doodle, a graphics editing software program that used to work on Commodore 64 computers. This was one of the first brands of home computers to gain wide popularity and it was sold extensively during the 1980s. At the current moment, JJ is considered an obsolete and rare format.

What are PSD files?

PSD is the default format for handling images using Adobe Photoshop and it represents a layered image file. PSDs allow later editing of available layers, including transparency, masks, alpha channels and texts, among others. After applying all desired editing, PSD files can be saved in Photoshop under more easily recognizable formats, such as JPEG or PNG, which are also smaller in size but flatten the image and hence do not allow later editing of layers.
