Extract text from QGIS and PowerCad files (QPJ)
To convert QPJ files to another format, you need QGIS or other GIS software.
To convert other file formats to the "GIS Map Projection File" file type, you need software like QGIS or a similar tool.
The .QPJ file functions primarily as a QGIS Project File or projection definition file associated with QGIS, an open-source Geographic Information System. In mapping workflows, it stores Coordinate Reference System (CRS) parameters to ensure spatial data aligns correctly. Alternatively, .QPJ is used as an electrical design project file by PowerCad.
The fundamental disadvantage of a .QPJ file is that it is a reference document. It does not contain actual vector map geometry, raster images, or electrical schematic data. It only holds file paths to external datasets, styling rules, and projection text. If a user receives a .QPJ file via email without the accompanying data (like SHP, DBF, or DWG files), it is entirely useless and will fail to open. Furthermore, these proprietary XML and text formats require an active installation of the host software, creating bottlenecks for users without expensive CAD or complex GIS software on their machines.
To share this data, users typically need to convert or export the workspace. QGIS maps are usually exported to PDF, PNG, or modern QGZ archives, while PowerCad designs are converted to standard DWG or DXF formats. Because .QPJ files lack embedded visual data and rely on local hard drive paths, standard online converters fail to process them. Often, only the original software can properly read or export the data. However, convert.guru can still identify the file format, inspect the file, and show text or internal XML content. Just drag and drop your file to see what it is and convert it if supported. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your QPJ file, detects the exact format, and lets you read the text inside.
Users also converted DBF, PRJ, QGS, GPKG and QIX files.
If you want to convert QPJ file to SHP, KML, KMZ, GPX, GEOJSON, TOPOJSON, TIF, TIFF, ECW, SID, IMG or DEM, you can use QGIS or similar software from the "GIS Project and Projection Data" category. In the File menu, look for Save As… or Export….
To convert LAZ, KMZ, DTM, CSV, DEM, PRJ, LAS, GPX, DSM, SHP, DBF or KML files to QPJ, try QGIS or another comparable tool in the "GIS Project and Projection Data" 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 QPJ converter.
