Convert QGIS to QGS

Understanding QGIS and QGS file formats

QGIS is a popular open-source Geographic Information System (GIS) application used for viewing, editing, and analyzing geospatial data. It supports a wide range of file formats for both vector and raster data. A QGS file is the native project file format for QGIS, storing information about map layers, styles, symbology, and project settings in XML format. The QGS file does not contain the actual data but references the data sources used in the project.

Why convert QGIS projects to QGS files?

When working in QGIS, your project can be saved in two formats: QGS (an XML-based file) and QGZ (a compressed archive containing the QGS file and auxiliary data). Converting your QGIS project to a QGS file is useful for version control, manual editing, or sharing project settings without bundling additional files.

How to save or convert a QGIS project to a QGS file

By default, QGIS may save projects as QGZ files. To save or convert your project to a QGS file, follow these steps:

1. Open your project in QGIS.
2. Go to File → Save As....
3. In the Save Project dialog, select QGIS Project Files (*.qgs) from the file type dropdown.
4. Choose your desired location and filename, then click Save.

This will create a QGS file containing your project settings.

Best software for QGIS to QGS conversion

The best and most reliable software for converting a QGIS project to a QGS file is QGIS itself. No third-party converters are needed, as QGIS natively supports saving projects in both QGS and QGZ formats. Always use the latest version of QGIS for optimal compatibility and features.

Tips for working with QGS files

• QGS files are plain XML and can be edited with a text editor for advanced customization.
• Ensure all referenced data sources are accessible when sharing QGS files with others.
• For backup or sharing, consider also exporting your data layers or using the Project → Package tool in QGIS.
