Convert PDF to DXF online
A PDF is a picture of a drawing; a DXF is measurable geometry. IngproCAD lets you use the PDF as a calibrated underlay and produce a clean, to-scale DXF.
Steps
- Drag the PDF onto the workspace: it is placed as a background.
- Press Calibrate, pick two known points and type the real distance.
- Trace over it with lines, polylines, circles and blocks using snaps and ortho mode.
- Export to DXF.
Accuracy
Once calibrated the drawing works at 1:1 in millimetres with 0.01 mm precision, endpoint, midpoint, centre, intersection and perpendicular snaps, and keyboard entry of exact distances.

Frequently asked questions
- How do I turn a PDF drawing into a DXF?
- Import the PDF as a background, calibrate it by picking two points and typing their real distance, trace the geometry with the CAD tools and export to DXF.
- Why does the PDF need calibrating?
- A PDF carries no drawing units. Giving the real distance between two points sets the sheet to 1:1 in millimetres so everything you draw over it is dimensionally correct.
- Will the DXF open in AutoCAD?
- Yes. The export writes standard DXF entities — lines, polylines, circles, arcs, text, dimensions and blocks.
- Can I use library blocks?
- Yes. Blocks placed over the calibrated PDF are exported as native DXF blocks.
