Conversion
Free
- Every mode, 5 files and 3 downloads a day
- Real lines, arcs, circles and texts, traced by code
- Layers by colour and type, the scale you set
Convert PNG to DWG online
To convert a PNG to DWG, drop the image of your plan below: each stroke becomes one centre line, circles and arcs become real CAD circles and arcs, and texts in English, French or Spanish become editable texts. Compare the drawing with your PNG, then download a DWG and a DXF, free, 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. Unreadable texts stay drawn as 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
- 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.
- TIFF
- The common output of large-format scanners and plan archives. Read like a PNG, first page only.
- 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.

| 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
Are the texts editable?
Texts in English, French or Spanish are read and written as real CAD texts. Texts we can't read stay drawn as lines, so nothing disappears.
My scan is crooked. Is that a problem?
No: a slightly rotated page is put straight before tracing.
What if the result has too many small bits?
Or if it misses thin lines: change the detail setting (less / more) on the preview and run it again. Your file stays uploaded.
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.
