- Layers by colour and type, the scale you set
Convert PDF to DWG online
To convert a PDF to DWG, drop the PDF in the converter below. A PDF exported from AutoCAD or Revit gives back its exact lines, texts and layers; a scanned PDF is detected and traced instead. Compare the drawing with your PDF, then download a DWG R2000 that any AutoCAD since 2000 opens, with a DXF next to it, free and with no account.
Free conversion, 3 a day. Max AI names the layers and reads the title block — free to try, $10 to export.
PDF, PNG, JPG or TIFF · up to 50 MB · Every mode free, 3 downloads a day · No 3D, no BIM. Texts turned into outlines in the PDF stay lines.

How it works
- 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.
- 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.

About the formats
- AutoCAD, Revit and ArchiCAD print plans to vector PDF: every line is stored as a path with its colour, often on a layer. That is what makes an exact PDF to DWG conversion possible. A scanned PDF holds none of it, only a picture, so it is traced.
- DWG
- Written as DWG R2000: every AutoCAD since 2000 opens it, and so do BricsCAD, DraftSight and ZWCAD. AutoCAD notes that the file was not saved by Autodesk software, as it does for any DWG written elsewhere. Drawings over 50,000 objects come as the DXF only.
- DXF
- The same drawing in DXF R2000, in the same zip: for software that prefers it, or to check the result in a free viewer.

| Preview | Free | Every mode: the drawing next to your file, 5 files a day. |
|---|---|---|
| Vector plan | Free | Lines and texts taken exactly, the PDF's layers kept. Texts turned into outlines in the PDF stay lines. |
| Scanned plan | Free | One centre line per stroke, real lines, arcs and circles, a crooked page put straight, texts read (English, French, Spanish). Unreadable texts stay drawn as lines. |
| Photo of a plan | Free | The sheet put flat from its 4 corners, shadows removed, then traced like a scanned plan. The whole sheet must be in the photo. |
| Detail / sketch | Free | Strokes straightened to 0 / 45 / 90°, perfect circles, closed outlines. Texts stay drawn as lines. |
| DWG / DXF to PDF | Free | A vector PDF, colours and line weights kept: one page per layout, or the model space fitted to an A3 sheet. |
| Downloads | Free | 3 zips a day (DXF + DWG), files up to 50 MB. |
| Max AI | Free to run | Layers named by meaning, the title block read, the scale found: results on the page, the picture watermarked. Once per file, 3 drawings a day. |
| Max AI export | $10 | Per drawing: the drawing with the layers you kept renamed and the title block as CSV and JSON, no watermark. Once Max AI has run on a file, this is its download. |
| Examples | Free | The DXF of each mode's example, to open in your own software first. |
FAQ
Which AutoCAD versions open the DWG?
Every AutoCAD since 2000, plus BricsCAD, DraftSight and most CAD software: the DWG is written as R2000, the most widely read version.
Can I convert a PDF exported from Revit?
Yes. Revit, ArchiCAD and other CAD software export vector PDFs: their lines, texts and layers come into the DWG as they are. You get a 2D drawing: walls stay lines, not BIM objects.
Will the DWG be editable in AutoCAD?
Yes: real lines, arcs and texts on layers, not an image pasted in a drawing. Only texts that the PDF already turned into outlines stay as lines.
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.
