Extract text from NTF files
To convert your NTF file to another format, you need GDAL or other GIS software.
To convert other file formats to the "Raster Map Format" file type, you need software like GDAL or a similar tool.
The .ntf extension most commonly identifies the National Imagery Transmission Format (NITF), a U.S. Department of Defense standard for exchanging digital imagery and intelligence data. Unlike standard images, NITF files are complex containers holding raster graphics, text, and extensive metadata in a single package. Because they are designed for military and GIS applications, they often use specialized compression (like JPEG 2000) and contain georeferencing data that standard photo viewers cannot interpret. Users frequently need to convert these to JPG, PNG, or PDF for general viewing, or GeoTIFF to preserve geospatial coordinates in software like QGIS or ArcGIS Pro.
A secondary but significant use of the .ntf extension is as a Lotus Notes Template (now HCL Notes). These files store the structural design (forms, views, agents) used to create functional Notes databases (.NSF). You cannot "open" these like a document; they must be instantiated via the HCL Domino Designer or client. Lastly, legacy NEATO MediaFACE software uses .ntf for CD/DVD label designs, a format now largely obsolete and difficult to access without the original 1990s software.
Convert.Guru analyzes your NTF file, detects the exact format, and lets you read the text inside.
Users also converted NITF, NEF, RTF, NCF, ID and SDOC files.
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 NTF converter.
