What is a .QGS file?
QGS is a QGIS project file, holding a map’s layers and styling. Created by QGIS.
- Did you know
- QGIS is the leading free, open-source desktop GIS.
- A QGS file is plain XML describing a map’s layers, symbology and settings rather than the geographic data itself, which stays in separate source files.
- QGS was QGIS’s default project format until version 3.2, when the zipped QGZ variant took over as the standard.
- What Analyser reads
- Identify and read more GIS and mapping files: OpenStreetMap o5m/o5c binaries, Esri layer files (.lyrx ArcGIS Pro CIM JSON, .lyr ArcMap), QGIS projects (.qgs/.qgz - version, CRS, layer list), shapefile spatial indexes (.sbn/.sbx), GMT/GDAL colour palettes (.cpt) and ENVI band-interleaved rasters (.bil/.bip/.bsq).
- Depth of analysis
- .QGS is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .QGS file
- Drag a .QGS file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
