QGIS is one of the most widely used open source GIS (Geographic Information System) software programs in the world. It allows users to view, analyze, and map geographic data using a wide range of tools.
Many users are looking for a portable version of QGIS for Windows so they can use the software without installing it and without administrator rights.
In certain contexts—universities, government agencies, local authorities, or companies—it is sometimes impossible to install software on a computer. Users do not always have administrator rights, or may simply want to test QGIS without modifying their system.
The solution is to use the portable version of QGIS.
Here I offer two portable versions of QGIS 4 for Windows, ready to use without installation.
