Extract text from ENP files
To convert your ENP file to another format, you need ADMIRALTY e-Reader or other Data software.
To convert other file formats to the "License Key or GIS Project" file type, you need software like ADMIRALTY e-Reader or a similar tool.
The .ENP extension is a classic example of a filename collision, shared by three distinct and incompatible technical ecosystems: maritime navigation, geospatial analysis, and data security.
Most commonly, an .ENP file is an Electronic Nautical Publication permit used by the UK Hydrographic Office (ADMIRALTY). These act as digital keys - small, proprietary encrypted strings - that unlock sailing directions and nautical charts within the ADMIRALTY e-Reader. The friction here is obvious: the file itself contains no readable text or maps. It is merely a license. You cannot "open" it in Microsoft Word or convert it directly to a PDF. To access the data, you must load the permit into the e-Reader, after which you can print specific pages to PDF for archiving.
Alternatively, in scientific circles, an .ENP file is associated with ENVI (Environment for Visualizing Images) by L3Harris. In this context, it serves as a project or preference file for geospatial image analysis. These files are tied to expensive, specialized software. Users without an ENVI license often need to convert the underlying raster data (managed by the project) into open formats like .GeoTIFF, JPG, or PNG for use in standard GIS tools like QGIS.
Finally, legacy security software from Entrust uses .ENP for encrypted file containers. These are essentially locked boxes; without the original password and Entrust software, the data inside is inaccessible. Users dealing with these archives are typically looking to decrypt and extract the original documents (e.g., DOCX, XLSX) rather than convert the container itself.
Convert.Guru analyzes your ENP file, detects the exact format, and lets you read the text inside.
Users also converted ENB, STAT, VTK and EDR files.
If you want to convert ENP file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use ADMIRALTY e-Reader or similar software from the "Electronic Nautical Publication Permit" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to ENP, try ADMIRALTY e-Reader or another comparable tool in the "Electronic Nautical Publication Permit" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ENP converter.
