How to convert DXF to DWG
Going the other way is simple, but the details decide whether the drawing behaves like a native one or like imported line spaghetti.
Why there is no uploader on this page
DXF is a closed format that no browser can read, so an in-page converter would have to send your file to a server. The procedure below does the job properly in the application that owns the format — and where a browser-side route exists, it is linked underneath.

Étape par étape
- 1Open the DXF in AutoCAD (or BricsCAD) — it opens directly, no import wizard needed.
- 2Save As → AutoCAD Drawing (*.dwg), choosing the version your team standardises on.
- 3Run AUDIT to fix errors carried over, then PURGE to drop unused layers and blocks the DXF brought with it.
- 4Re-map layers to your office standard (LAYTRANS with a standards file) before the drawing joins a live project.
- 5Check units: if the geometry lands at the wrong scale, the DXF had different INSUNITS — scale by 25.4 or 1/25.4 as needed.
Points de vigilance
- ODA File Converter batch-converts folders of DXF to DWG for free.
- Text styles referencing fonts you do not have will be substituted — bring the SHX/TTF files with the file.
Autodesk's documented text interchange format for 2D/3D CAD geometry — readable by every CAD package and, unlike DWG, by open-source tools.
AutoCAD's native binary drawing format. Closed and version-specific, so it needs AutoCAD or a licensed library to read.
Questions fréquentes des dessinateurs
Will the DWG be a proper AutoCAD drawing?
Yes, but it inherits the DXF's layer names, text styles and units. Budget ten minutes for layer translation and a PURGE/AUDIT pass.
Why is my geometry 25.4 times too big or small?
A millimetre drawing was read as inches, or the reverse. Scale the whole drawing by 25.4 or 0.0394 and set INSUNITS correctly.
