PDF to DXF
This tool exports PDF files with vector geometry to DXF format for CAD applications. Lines, curves, rectangles and technical contours are extracted from PDF drawing paths and exported as DXF geometry.
The generated DXF files can then be edited further in various CAD systems and used for engineering applications.
Especially suitable for:
- PDF exports from CAD or design tools
- 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 design engineers, engineers and technical specialists quickly convert PDF vector data to DXF format for CAD applications.
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 the conversion work?
During processing, various analysis and conversion steps are performed:
- Upload PDF file
- Read vector paths on all pages (PyMuPDF)
- Export text 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 combined DXF file.
Optionally, a scale value in millimetres per PDF point can be specified. If omitted, 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 scanned PDFs without vector data (please use “Image to DXF”)
- text that has already been converted to paths in the PDF (outlines)
- complex freeform surfaces and hatching
- embedded images and raster content
- very complex PDFs with thousands of paths
Usage
Select a PDF file and start DXF generation. After processing completes, the generated DXF file can be downloaded.
Optionally, a scale value for PDF points can be specified, for example if the PDF comes from a specific export.
