Floor plan to CAD converter

Drop a floor plan PDF below. Walls, doors, furniture and room names come out as an editable DXF, and two clicks on a known wall bring the plan back to real size.

Converted on your device. Nothing is uploaded. Several PDFs at once with the batch pass.

This floor plan to CAD converter turns the PDF an architect, estate agent or builder sent you into a DXF you can edit in AutoCAD or any other CAD program. It runs in your browser, so the plan of a client’s home never leaves your computer.

Floor plan PDF to CAD in three steps

1Drop the planthe preview shows the page; pick the floor if the PDF has several
2Set the scaleclick both ends of a dimensioned wall and type its length, such as 10 000 mm
3Download the DXFwalls, doors, furniture and room names on layers by colour

What does a converted floor plan look like?

We drew a test apartment of 10.0 x 7.2 m at 1:50 on A3, the way an architect’s program exports it, and ran it through the converter above.

Converter with the floor plan loaded and the scale set: the bottom outer wall is picked with two blue points and the length 10000 mm is applied — Scale set with two clicks on the 10 000 mm outer wall. The blue line shows the picked distance.

The converted floor plan DXF: outer and inner walls, five rooms with labels, door swings, a table and dimension lines 10 000 and 7 200 — The DXF, rendered from the file: 26 lines and shapes and 8 text items. The outer wall measures 9 996 mm after the two-click scale, 10 000.0 mm with the 1:50 factor.

Download both and try them in your own CAD program: floor-plan.pdf and floor-plan.dxf.

Which settings matter for floor plans?

Setting	What to choose	Why
Output units	Millimetres in metric countries, inches in the US	Matches the dimensions printed on the plan
Set scale	A long outer wall with a printed dimension	Longer lines mean a smaller error from your clicks
Text	On	Room names and dimension figures stay editable
Filled areas	Off for clean walls, on for hatched walls	Solid wall fills come across as closed outlines on their own layer
Trace scanned pages	On	Only used when the page turns out to be a scan

Why does the scale matter so much on a floor plan?

Floor plans are drawn small. The same 10 m wall is a very different length on paper depending on the scale printed in the title block:

Length of a 10 m wall on the printed sheet

Length of a 10 m wall on the printed sheet
1:20	500 mm
1:50	200 mm
1:100	100 mm
1:200	50 mm

Without a scale the DXF keeps these paper lengths. One known dimension fixes all of them at once.

So check the title block first. If it says 1:100 but the plan was printed with “fit to page”, the printed scale is no longer true, which is one more reason to scale from a dimension rather than from the label. Our guide on how to scale a PDF drawing walks through the edge cases.

Vector floor plan or scanned floor plan?

What you get from each kind of floor plan PDF

Scanned or photographed plan

Ink traced into outlines around every line
Room names arrive as shapes, not text
About 0.4% size error from line thickness and skew
Good as a background to redraw over

Plan exported from CAD or BIM

Exact lines, arcs and polylines
Room names and dimensions as editable text
No measurable size error after scaling
Ready to edit, dimension and print

Not sure which one you have? Zoom in on a wall: a vector plan stays sharp at any zoom, a scan turns blurry. For scans, see scanned PDF to CAD; if your office needs DWG, convert here and save as DWG (PDF to DWG).

What do architects do next with the DXF?

Most put the converted plan on a locked background layer and draw new walls over it: an extension, a kitchen layout, a measured survey check. The PDF to CAD Handbook covers that workflow step by step in converting architectural PDFs to CAD, including layer clean-up and the 1:50 and 1:100 conventions.

Questions about floor plan to cad converter

Will the walls come out as walls?

They come out as lines and polylines, exactly as the architect's program drew them. CAD programs only know walls as objects inside BIM software; a converted plan gives you the geometry to trace over or edit.

My floor plan says 1:100 but the DXF is tiny. Why?

A PDF stores paper size, so a 10 m wall at 1:100 is 100 mm on the sheet. Click Set scale, pick both ends of a dimension you know and type its real length: every line is multiplied to real size.

Can I convert a floor plan photo or scan?

Yes. The converter traces the ink of a scanned page into outlines. It works as a guide to redraw over; a PDF exported from the architect's software converts far more cleanly.

Which CAD programs open the result?

Every one that reads DXF: AutoCAD, AutoCAD LT, BricsCAD, DraftSight, LibreCAD, QCAD, FreeCAD, SketchUp Pro, Vectorworks and ArchiCAD among them.
