LibreCAD is a 2D CAD drawing tool based on the community edition of QCAD. LibreCAD uses the cross-platform framework Qt, which means it works with most operating systems. The user interface is translated in over 30 languages. https://translate.librecad.org

LibreCAD can be used as DXF to a PDF, PNG, or SVG converter. For example, to convert a foo.dxf to foo.pdf, foo.png, or foo.svg:
$ librecad dxf2pdf foo.dxf
$ librecad dxf2png foo.dxf
$ librecad dxf2svg foo.dxfThe macOS build is a universal (Apple Silicon + Intel) app. It is ad-hoc signed rather than signed with an Apple Developer ID, so it is not notarized: macOS still shows an unidentified-developer warning on first launch. Open it once via right-click → Open, or clear the quarantine attribute (#2162):
xattr -rc LibreCAD.applibdxfrw is an associated project that allows LibreCAD to read DXF and DWG files.
LibreCAD can natively import ESRI Shapefiles (.shp/.shx/.dbf), built with shapelib. Points, polylines/arcs, and polygons are imported as native entities (Z preserved), with DBF-driven layers and per-entity styling (color, linetype, width) where the corresponding fields are present. Import is read-only; there is no Shapefile export.
