Project: QGIS
Version: 3.10 LTR
Previous QGIS versions would often generate HUGE PDF (or SVG) outputs, as these outputs included many redundant vertices which were not discernably different at the export DPI. Now, by default, we apply a simplification while writing out PDF or SVG files, causing geometries to be simplified and automatically removing any redundant vertices which are (e.g. if export DPI is 300 dpi, vertices less then 1/600 inch different from each other will be removed).
This new setting, "Simplify geometries to reduce output file size", is exposed in the SVG or PDF export settings dialogs shown when exporting a layout/atlas/report to PDF or SVG.
No more ridiculously complex and large export file size for your QGIS print layouts! Aside from the file size issues, these also cause problems when trying to load into other applications, e.g. Inkscape, which chokes on the huge number of vertices and grinds to a crawl.... ouch!
