What is an NPPP file

NPPP files mostly belong to Nitro Pro. Your NPPP file is a container that holds data in different internal formats. It does not follow one fixed structure.

Encrypted Image: The file holds an encrypted image stored in JPG format – this was used in the Nero PhotoSnapViewer project.

ZIP Archive: some of NPPP files use a ZIP format to hold what is called a Nitro Pro Proof File.

PDF Portfolio: Some are created as Nitro Pro PDF Portfolios. You can open these with a PDF reader. More details are available at Nitro’s website.

Encrypted Document: some are Nitro Pro Encrypted Documents associated with STOP ransomware. See this resource for decryption details.

FilExt.com notes: This file type relies on checking the internal file signature. If the header shows JPG markers, an image viewer may work; if it presents ZIP markers, a decompression tool is needed; if PDF markers are found, then a PDF reader is appropriate. In some cases, decryption with Nitro Pro or a related key is necessary to view the content.

How to open NPPP files

You need a suitable software like Nitro Pro to open an NPPP file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your NPPP file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a NPPP file directly in the browser:.

NPPP file format details:

To find out what program is needed to open NPPP files, you need to determine the file format. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. If there are problems opening a file, you must first determine the file format used. Our evaluation of the NPPP files looks like this:

The NPPP file extension is rarely used and includes different formats for different programs. But the following two file formats are common:

25% of all NPPP files save the data in JPG file format. JPEG is the standard image format for lossy and compressed image data. They consist of illegible, cryptic characters. A typical file size is 1 MB. The file type is a fairly new file format. A usual file name is 20180601.jpg.nppp.
20% of all NPPP files internally use the ZIP format, i.e. an NPPP file contains several compressed files. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. The files are on average 26 KB in size and range from 13 KB to 310 KB. These files can be linked to docx and xlsx.

The remaining 55% of all NPPP files are different files with different signatures, such as PDF and EXE. If you want to find out what your NPPP file contains, drag and drop it onto this page.
