How to Convert PDF to DXF in Your Browser
Most engineering PDFs started life in CAD. The CAD file stayed behind; the PDF is what got emailed. Every line and arc in it is still a vector with exact coordinates, and this converter reads those vectors straight out of the file.
Drop a PDF on the preview and pick a page. The whole PDF to DXF workflow then runs top to bottom in the sidebar: crop a zone, set an origin, set the scale, apply point cleaning, and download the DXF.
Extraction, not tracing
An autotracer looks at pixels and guesses where the edges are. This tool copies the endpoints your CAD system wrote into the PDF, so a line that was straight in the original is straight in your DXF, at the same coordinates.
What the preview shows is what converts
The extractor reads the page the way a renderer draws it: it follows clipping paths, form bounding boxes, soft masks and paint order. Hidden pasteboard copies and masked-out duplicates, which lurk inside many CAD exports, never reach your DXF.
Text and raster images are skipped on purpose: on an engineering drawing, the stroked and filled paths are the geometry. If a page reports no vectors, it is a scan, and there is no line-work in the file to extract.
Getting Real Dimensions Out of the Drawing
PDF pages are measured in points, 1/72 of an inch, so an unscaled export reproduces the drawing at paper size. Two tools turn paper size into part size.
Pick the sheet scale
If the title block says 1:4, pick 1:4 from the viewport dropdown; enlarged details go the other way, 2:1 and up. Every readout multiplies through immediately.
Or measure one dimensioned feature
Better still, click across any feature that carries a dimension with the two-point scale tool and type the real distance. The picker snaps to endpoints and lines, and Shift locks horizontal or vertical.
From then on, every readout and the exported DXF speak in real part units.
Origin, Snapping and Measuring
Put (0,0) where your CAD wants it
Click a point and it becomes DXF (0,0). Or click two lines and their intersection becomes the origin: the lines are extended first, so a taper apex or an implied corner that is never actually drawn on the sheet still works.
With no origin set, (0,0) is the geometry's lower-left corner.
Check a dimension before you export
Measure between two points, or between two lines: the angle, and the gap when they are parallel. The pointer snaps to endpoints, onto lines, and to the horizontal and vertical through your first point, so point-to-line distances come out as clean ΔX or ΔY values.
Your Drawing Never Leaves Your Machine
PDF to DXF conversion runs entirely in your browser: a WebAssembly parser opens the file right on your machine, and nothing is uploaded. Load the page, pull the network cable, and it still converts.
So a customer's print, a supplier's proprietary drawing, or your own unreleased design can go through it without landing on anyone's server.
