Convert PDF to CAD online

To convert a PDF to CAD, drop it below: we look at the page first. If it holds vector lines, they are taken exactly, with their texts and layers; if it is a scan, it is traced into one line per stroke and its texts are read. You see which one it was, compare the drawing with your PDF, and download a DWG and a DXF, free.

How it works

  1. Drop your filePick what you have: a PDF from CAD, a scan, a photo of a sheet or a sketch. Up to 50 MB, no account.
  2. CompareSlide between your file and the CAD drawing, check the counts of lines, arcs and texts. Change the detail, the corners or the frame and run it again. Set the scale if you know it.
  3. DownloadA zip with the DXF and the DWG, free in every mode, 3 times a day.

About the formats

PDF
Two kinds of PDF hold a plan. A CAD export stores vector paths, so the drawing is read as it is, layers included. A scan stores a picture of the sheet, so the drawing is traced. The converter tells them apart on its own.
DWG
The native format of AutoCAD, the one most offices exchange. Written as DWG R2000 so the widest range of software reads it; very large drawings (over 50,000 objects) come as the DXF only.
DXF
The open twin of DWG, read by almost every CAD and GIS program, free ones included (LibreCAD, QCAD, FreeCAD, QGIS). Take it if your software is not AutoCAD.

FAQ

How do I know if my PDF is vector or scanned?

Zoom in a lot: vector lines stay sharp, a scan turns into pixels. You don't have to check: the converter looks at the page and says which mode it used.

Which CAD software can open the result?

AutoCAD, BricsCAD, DraftSight, LibreCAD, QCAD and FreeCAD, and QGIS for maps: the DWG and the DXF are both R2000, a version they all read.

Does it work on a hand-drawn plan in PDF?

Yes, once scanned: it is traced like any scan. For a freehand sketch, pick Detail / sketch to get straight lines, round circles and closed outlines.

What happens to my files?

Your files are deleted after 24 hours and never used for AI training. They are only used to make your conversion.

Who owns the converted drawing?

You do. You keep the ownership of your file and of the DXF and DWG made from it, commercial use included.

Do I need an account?

No. Drop a file, check the preview, download. The job page keeps your result for 24 hours.

What is in the download?

A zip with a DXF and a DWG (both R2000); a vector PDF from the DWG and DXF to PDF pages. Drawings over 50,000 objects come as the DXF only, with a note: save it as DWG in your software.

Is the drawing to scale?

Without a scale, a PDF comes in millimetres of paper and an image in pixels. On the preview, type the scale (1:100) or click two points and give the real distance between them.

Does it make 3D or BIM models?

No: you get a 2D drawing, lines, arcs, circles, fills and texts on layers. No 3D, no walls or rooms as BIM objects.

Are there limits on free conversions?

Free in every mode: 5 files and 3 downloads a day per visitor, files up to 50 MB, one PDF page per file. The counters reset at midnight UTC. Every example's DXF is free too.

What if the file doesn't open?

Write to us with the job page's address: we fix the conversion.
