Convert an image to CAD online

To convert an image to CAD, drop a scan, a photo of a sheet or a sketch below and pick the mode that fits it. The engine traces real lines, arcs, circles and texts on layers, with no AI guessing the geometry. Compare the result with your image, then download a DWG and a DXF, free, 3 times a day.

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

PNG
A lossless image: scans and screenshots keep sharp edges, which gives the cleanest tracing. 200 dpi is enough for most plans; images over 60 megapixels are refused.
JPG
The usual format of a phone photo. Compression blurs thin lines a little, so take the photo close, in even light, with the whole sheet and its 4 corners in the frame.
TIFF
The common output of large-format scanners and plan archives. Read like a PNG, first page only.
PDF
A PDF exported from CAD software keeps the drawing as vector paths: Vector plan reads them as they are, nothing is traced. A scanned PDF is only a picture of the sheet, so it goes to Scanned plan. We tell you which one you have before you download.
DWG
AutoCAD's own format, written as DWG R2000 so that any AutoCAD since 2000 opens it. Drawings over 50,000 objects come as the DXF only, with a note: open it and save it as DWG in your software.
DXF
Autodesk's open exchange format. We write DXF R2000, which AutoCAD, BricsCAD, DraftSight, LibreCAD, QCAD, FreeCAD and QGIS open. Each colour and type of object gets its own layer.

PreviewFreeEvery mode: the drawing next to your file, 5 files a day.
Vector planFreeLines and texts taken exactly, the PDF's layers kept. Texts turned into outlines in the PDF stay lines.

FAQ

Which mode should I pick?

Vector plan for a PDF exported from CAD, Scanned plan for a scan, Photo of a plan for a phone photo of a sheet, Detail / sketch for a symbol, a detail or a freehand drawing.

Can I convert a freehand sketch?

Yes, in Detail / sketch: frame the useful part of the image, and strokes are straightened to 0, 45 and 90°, circles made round and outlines closed. Its texts stay drawn as lines.

Does it work on a colour plan?

Yes: each colour gets its own layers, one per type of object, named like ROUGE_LIGNES (red 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?
