PDN to CAL Conversion: FAQ

What are PDN files?

PDN is the native file format used by Paint.NET, a popular free image and photo editing software for Windows. A PDN file stores the entire project data for an image, including layers, layer properties, transparency, blending modes, text, and editing history. Unlike standard image formats like JPEG or PNG, which flatten an image into a single layer, PDN files preserve all editable elements, making them ideal for ongoing design work or complex image editing tasks.

What are CAL files?

A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
