PDN to HPG 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 HPG files?

HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics.
