DXF to DWG Converter

Upload a .dxf drawing and download it as a native DWG. A real DWG writer does the work, so the result opens clean and passes integrity audits.

How to convert DXF to DWG

Upload your DXF file

Drop the .dxf on the converter or click to browse — up to 100 MB, several files at once are fine.

We rewrite it as DWG

Nothing is traced or redrawn — a DWG writer re-encodes the same entities, layers and coordinates into the native container.

Download a real DWG

You get a native 2018-format DWG with editable LWPOLYLINE geometry on its own A-SKETCH layer — editable geometry, ready to draft on, not a picture to trace again.

About DXF to DWG conversion

This is the one page on the site that does not involve tracing anything. DXF and DWG describe the same drawing; DXF is the documented text interchange format, DWG is the native binary one CAD programs actually save. Converting between them is a re-encoding, not an interpretation, so coordinates come through to the same precision they went in with and nothing is approximated.

The reason people need it is social rather than technical. Send a DXF to a fabricator, a consultant or a client running a plain CAD seat and you will often get "can you send the DWG?" back — DWG is the deliverable of record in most workflows, and some plan-check portals reject anything else. Drawings that are pure geometry — lines, polylines, arcs, circles, text, layers — round-trip losslessly. Exotic proxy objects written by other applications have no DWG equivalent and are skipped rather than written out corrupted, which is the right trade: a file that opens cleanly missing an oddity beats one the reader refuses.

Frequently asked questions

Which DXF versions can I upload, and what DWG comes out?

ASCII DXF from R12 through 2018 is accepted. Output is 2018-format DWG, with an automatic fallback to R2000 DWG if the primary writer is unavailable — both open in every current CAD application.

Are layers, blocks and dimensions preserved?

Entities, layers and coordinates carry across. Standard geometry — lines, polylines, arcs, circles, text — is lossless. Proxy and custom objects written by third-party applications have no DWG equivalent and are skipped rather than written out broken.

Will the converted DWG pass a CAD integrity audit?

Yes. The file is produced by a real DWG writer rather than a renamed DXF, so audit tools report no errors on it. If a specific drawing does flag something, it is worth telling us — that is a bug, not expected behaviour.

Can you convert DWG back to DXF?

Not yet — the pipeline reads DXF and writes DWG, not the reverse. If you have a DWG and need DXF, any CAD application can save it out as DXF; a hosted DWG reader is on the roadmap.

Can you convert a PDF to DWG?

No. This site reads images and DXF only — there is no PDF parser in the pipeline, and a page claiming otherwise would waste your upload. If your PDF holds a vector drawing, your CAD's own PDF import gives a far better result than any raster trace. If it is a scanned page, export it as PNG or TIFF at 300 DPI and use the image converters here.
