What is an NPP file?
An .NPP file is most commonly an Art Explosion Publisher Pro Document. Nova Development created this format for their desktop publishing software. These files contain page layouts, text, and images for printed materials. The software saves these layouts using the standard DOC file structure under the .NPP extension.
However, the .NPP extension has multiple possible meanings. It can also be an Express Points presentation file by NCH Software, a plugin file for Nitro PDF Pro, a project file for Serif PagePlus, or a simple text document associated with Notepad++.
How to open NPP files?
To open an Art Explosion Publisher Pro Document, you normally need the original software from Nova Development. If the file is a plugin, Nitro PDF Pro will process it. Because there are many different types of .NPP files, it is difficult to know which program to use.
viewer.online/npp analyzes .NPP files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If your file has multiple possible meanings, we recommend using viewer.online/npp to identify the actual format of your file.
Summary
Because .NPP files use the known DOC format, viewer.online/npp can safely open and display them online, eliminating compatibility problems.
