PDN to FITS 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 FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades. FITS files contain not just images, but also data related to photometry and spatial calibration, and information about the origin of the image. Similar formats include FIT and FTS.
