PDF to DXF
This tool exports PDF files with vector geometry to DXF for CAD applications. Lines, curves, rectangles and technical contours are detected from PDF drawing paths and output as DXF geometry.
The generated DXF files can then be edited in various CAD systems and used for technical applications.
Especially suitable for:
- PDF exports from CAD or design programs
- technical drawings and plans as vector PDF
- laser and CNC templates from PDF
- DXF preparation from PDF contours
- simple technical schematics and contours
What is PDF to DXF used for?
The tool helps designers, engineers and technical specialists quickly convert PDF vector data into DXF for CAD use.
Typical applications:
- further processing of CAD PDF exports
- extraction of contours from technical PDFs
- laser and CNC preparation
- conversion of PDF geometry into editable DXF data
- support for reverse engineering and digitisation
How does conversion work?
Processing includes several analysis and conversion steps:
- Upload a PDF file
- Read vector paths on all pages (PyMuPDF)
- Export texts and dimension values as MTEXT
- Detect lines, curves and rectangles
- Convert PDF geometry to DXF (ezdxf)
- Download the generated DXF file
Curves are approximated. The Y axis is adjusted automatically for CAD systems. All PDF pages are exported into one shared DXF file.
Optionally a scale in millimetres per PDF point can be specified. Without a value the default is:
1 PDF point = 25.4 / 72 mm (approx. 0.3528 mm)
Current limitations
The tool processes only PDF files with embedded vector geometry. Not supported or limited:
- pure scan PDFs without vector data (please use Image to DXF)
- texts already converted to paths (outlines) in the PDF
- complex freeform surfaces and hatching
- embedded images and raster content
- very complex PDFs with thousands of paths
How to use
Select a PDF file and start DXF generation. After processing you can download the generated DXF file.
Optionally specify a scale for PDF points, for example if the PDF comes from a special export.
