An INP file is a document created by Urdu InPage, a multilingual publishing application for the Urdu, Arabic, Persian, and English languages. It contains text saved in the Noorinastaliq font, which displays Urdu in nastaliq script. INP files also support standard page layout formatting.

Since the INP file format is not widely supported you may need to export it as an .EPS file in InPage in order to share the file. However, the file will most likely be large in size, which may make it more difficult to share via email, and may need it be shared via cloud storage.
