The following PyQGIS script is useful when wanting to export out multiple layouts from a QGIS project. It will export out all layouts from a project into the project folder. Handy when you've made tweaks to the base map:
import os project_instance = QgsProject.instance() manager = project_instance.layoutManager() for layout in manager.layouts(): exporter = QgsLayoutExporter(layout) outpath = os.path.join(project_instance.homePath(), layout.name() + ".pdf") exporter.exportToPdf(outpath, QgsLayoutExporter.PdfExportSettings())
There may be plugins available that achieve the same/similar things, but this script is a handy one to have.
