Choose QGIS when
When QGIS is the better choice
- Budget: QGIS is completely free. No licensing costs, no seat limits, no subscription.
- Open formats: QGIS reads and writes virtually all GIS formats via GDAL/OGR. No vendor lock-in.
- Cross-platform: Your team uses a mix of Windows, macOS and Linux.
- Education: Teaching GIS without software licensing costs.
- Open source ecosystem: You want to contribute to or customise the software.
- Standard GIS tasks: Cartography, spatial analysis, data editing, and most day-to-day GIS work.
Choose ArcGIS when
When ArcGIS is the better choice
- Enterprise deployment: Large organisations needing ArcGIS Server, Portal or Online integration.
- Advanced 3D: Complex 3D scene analysis, CityEngine integration.
- Network analysis: Route optimisation, service area analysis with Network Analyst.
- Existing Esri ecosystem: Your organisation already uses ArcGIS Online, Survey123, or Field Maps.
- Formal support: Paid support contracts required by your organisation.

FAQ
QGIS vs ArcGIS questions
Can I open ArcGIS files in QGIS?
Yes for most formats. QGIS can open Shapefiles (.shp), File Geodatabases (.gdb) in read mode, GeoTIFF rasters, and connect to ArcGIS REST services. It cannot read .mxd map documents directly, but can open the underlying data layers.
Is QGIS good enough for professional GIS work?
Yes. QGIS is used extensively by governments, NGOs, environmental consultants, and universities worldwide. It handles all standard GIS workflows. The main gap vs ArcGIS Pro is in specific Esri-ecosystem integrations and some advanced 3D and network tools.
Which is easier to learn?
Both have a similar learning curve for core GIS concepts. QGIS has excellent documentation and a large community with free tutorials. ArcGIS has Esri training resources and a structured certification path. Neither is dramatically easier than the other for a beginner.
