What is a(n) PDN file?

The PDN (Paint.NET Image Format) is a file format used for storing raster images created with Paint.NET. It provides support for multiple layers, transparency, and an array of other image editing features. This format utilizes a compressed variant of the Microsoft Windows bitmap (BMP) type for storage, allowing for high quality imaging without taking up large amounts of memory.

The PDN format is widely used by digital artists since it was designed to be extensible; allowing users to write their own plugins to extend Paint.NET’s functionality even further. As this file format supports natively saving and loading layered image files, it is often preferred over other file formats that do not support this natively, such as JPEG or TIFF.

How to open PDN file?

There could be multiple reasons for which the system does not support given file. In the case of PDN extension, it is probable that none of the installed programs support given file type. Therefore, user should undertake the following steps

Step 1: Install a program that supports PDN files

If an application that supports PDN files is installed on user’s system, but is not used to open such files by default, right-click on the file icon and choose "Open with" option from the menu. Next, select the proper application and check the "Always use the selected application to open this kind of files" box. The system will store this information in its registry and use the selected program to open files with PDN extension by default.

For Mac OS users the procedure is analogous – open the file menu by right-clicking on the PDN file and choose "Information" option and select "Open with program" option. From the submenu select an application and click on "Change all" button.

Step 2: Find and download proper software

Inability to open PDN files may also be related to the lack of any application that supports given file being installed on the system. Should that be the case, user needs to download and install one of the following applications. Once installed, the system will automatically associate newly installed application with PDN files. If this step fails, see step 1.

Sometimes, although relatively rarely, steps 1 and 2 might not lead to expected results. There can be several reasons for such situation to occur:

  • PDN file has been downloaded from the internet but for some reason it is incomplete. In such case the file should be re-downloaded and opened again.
  • Structure of given PDN file could be corrupted and as such the program is not able to open the file
  • Storage medium on which the file was stored is damaged
  • It is important to ascertain that the icon representing given file is not a shortcut a related PDN file no longer present in the location to which the shortcut points
  • If the user account has restricted access privileges it is advised to contact the system administrator or an IT expert
