To convert a PDF or JPG floor plan to DXF or DWG, upload the file to INK TO BRICK, let the conversion reconstruct it as a conceptual 3D model, then export a plan drawing in DXF or DWG from that model. The drawing arrives layered: rooms, walls, openings, fixtures, labels and dimensions each sit on their own layer, printed to A4, A3 or Letter at a scale you pick between 1:10 and 1:1000. DXF and DWG export are on Pro and Team. This page is for anyone holding a flat plan, a scan or a listing image who needs geometry a CAD program can edit rather than a picture of a drawing.
Does converting a JPG floor plan to CAD just trace the image?
No, and the difference matters more than it sounds. A trace copies the marks on the page: every hatch line, every scanner speck, every broken edge becomes a vector, and you inherit a pile of line work with no idea which closed loop is a kitchen. A reconstruction reads the drawing, decides what it is looking at, and rebuilds rooms, walls and openings as named geometry. The file you download is drawn from that model, which is why it can carry a rooms layer at all, and why the CAD drawing is a redrawing of your plan rather than a vectorized photocopy of it.
The same mechanism sets the limit. The drawing inherits the model’s reading of your source, so a doorway misread as a window or a partition misread as casework arrives in CAD as the thing the model reconstructed. That can happen even when the source is legible. Open the model in the browser and check the openings before you export, because a wrong line is cheaper to notice in the viewer than in a drawing you have already drafted over. Checking doors and windows walks that pass.
Provide scale evidence before the run: the drawing’s original units, scale denominator, and up to 30 named reference measurements. Use dimensions you can verify rather than assumed standard sizes. The conversion interprets scale from the source and context; one supplied length does not guarantee that it resolves correctly. Read the reported scale status and compare a second independent dimension in another part of the model. Choosing 1:50 for the exported sheet does not repair unresolved or incorrect model scale.
What is inside the DXF or DWG file?
A plan export writes six layers, and you choose which of them to include. Layers are the reason a CAD handoff beats a PDF: the person receiving the file can freeze what they do not want, snap to what they do, and draft their own work on top without deleting yours.

In the model’s metric units, a run labeled 3.20 m is 10 ft 6 in.You dimension to your own standard, to your own faces, and would rather start clean.Then you choose the sheet. Paper is A4, A3 or Letter. Scale runs from 1:10 to 1:1000, and 1:100 is the default. Orientation is landscape or portrait. On a multi-floor project, which can cover up to your plan’s floor limit, you also pick which floors go into the export. The gating is worth stating plainly: SVG and PDF plans come on any plan at the default sheet, A3 landscape at 1:100 with every layer on, while changing the paper, scale, orientation, layer set or floor selection needs the export controls that come with Pro and Team. DXF and DWG are on Pro and Team whatever sheet you pick.
How do you open the file in AutoCAD, BricsCAD, LibreCAD, DraftSight or Revit?
Each program documents its own DXF and DWG handling, and those documents are the thing to follow. What follows is where each vendor writes it down, not a compatibility promise from us.
- AutoCAD. Autodesk’s page on importing and exporting DXF files covers the format and notes that you can convert a DXF to DWG by opening it and saving it in DWG format.
- BricsCAD. Bricsys documents the DWG and DXF versions BricsCAD opens and saves, with OPEN for a file in its own tab and IMPORT for geometry dropped into a drawing you already have open.
- LibreCAD. The manual lists reading DWG and DXF and writing DXF, SVG and PDF, and the project FAQ names the DXF versions it supports, R12, R14, 2000, 2004 and 2007, while stating that it does not support every feature of the format.
- DraftSight. The Dassault Systèmes DraftSight migration guide states that it opens, edits and saves legacy DWG versions back to AutoCAD Release 12.
- Revit, as an underlay. Autodesk documents linking a CAD file instead of importing it, with DWG and DXF among the linkable formats, and a linked 2D drawing showing in the plan views you draft over.
Check units before you check anything else. A DXF carries geometry in drawing units, and the receiving program has to be told what one unit means, which is why Autodesk keeps a note on units of measurement. Once the file opens, measure one length you already know, a door width or the overall depth, and compare it with your source plan. A reading off by a factor of 1000, meters read as millimeters, or by 25.4, inches read as millimeters, is a unit mismatch rather than a geometry problem. Then confirm the scale: a sheet exported at 1:50 is not a sheet at 1:100 with heavier lines, and printing one as the other halves every dimension anybody scales off it.
When is SVG or PDF enough, and when is IFC the better handoff?
Pick the format by what the person receiving it is going to do, not by which one sounds most professional. All four plan formats come off the same model, so the only question is what happens to the file next.
- SVG, when the drawing goes into a layout, a deck or a web page and gets restyled rather than edited as building geometry. With any plan.
- PDF, when somebody is going to print it, mark it up and send it back. With any plan.
- DXF or DWG, when the receiver drafts on top of it in CAD and needs layers they can freeze, lines they can snap to and dimensions they can extend. On Pro and Team.
- IFC, when the receiver works in BIM and wants rooms, walls and openings as building objects carrying their own data instead of lines on layers. IFC is on Pro and Team, and it is the better handoff the moment the word coordination appears in the conversation.

What INK TO BRICK does here
You upload one floor plan as a PDF, PNG, JPEG, SVG or DXF file of up to 25 MiB. Choose the required PDF page and crop in the local preparation workspace before uploading. The conversion reconstructs rooms, walls and openings as a conceptual 3D model you explore in the browser. With a plan you furnish and finish it in the editor and export it. The floor plan to 3D page shows what that run produces, and the PDF to 3D guide covers the upload end in detail. Export needs a plan; the library is included on every plan, and DXF and DWG require Pro or Team, alongside the export controls that let you set paper, scale, orientation, layers and floors. Pricing lists what each plan includes.
The common reason to want CAD out of a scanned plan is a renovation: an existing-conditions drawing you can measure, mark up and hand to whoever is doing the work. Renovation planning covers what the model gives you for that job and what it does not, and measuring a floor plan PDF is the manual method to check any number the export prints.
Try it and check your result
Open the CAD file in a new drawing and toggle the openings and dimensions layers separately. Measure one overall run and a second room dimension; compare them with the source rather than the exported labels alone. For a printed review, check a scale bar at the intended paper size with fit-to-page disabled. If either geometric check disagrees, resolve units or model scale before drafting on top.
Inspect a reference in 3D
Orbit from two sides and locate an opening and a material boundary. Use those landmarks when checking a file in its destination application; this reference does not validate your import or export.
