Convert DXF to DWG online
Convert a DXF (.dxf) drawing to DWG (.dwg) for AutoCAD and DWG-compatible drafting workflows. Supported geometry, layers, blocks, dimensions and text can transfer, but fonts, external references, proxy objects, plot settings and application-specific data must be checked after conversion.

No desktop software
Start the DXF-to-DWG workflow in your browser without installing a CAD application or conversion plugin.
Drawing-aware exchange
Move supported DXF entities into a DWG-compatible file while keeping the original DXF as the neutral exchange source.
Ready to inspect
Open the DWG in the target drafting application and compare units, layers, blocks, hatches, dimensions, text and layouts with the original drawing.
Open in a DWG-compatible applicationPrivate file handling
Conversion files stay private, are not added to the public CAD library and are automatically deleted within 7 days.
Continue your workflow
Inspect the DXF, verify the DWG or request specialist help
Review the DXF source, validate the converted DWG in the receiving application and request drafting support when unsupported entities need reconstruction.
Simple conversion workflow
How to convert DXF to DWG online
Move from a DXF exchange drawing to a DWG-compatible drawing in three steps.
Upload the DXF file
Choose one .dxf file up to 300 MB. Confirm that it opens correctly and that any required fonts, line types, images or references are available.
Convert to DWG
The route is preconfigured for DWG output. Start the conversion without searching through a destination-format menu.
Download and verify
Open the .dwg in the exact CAD version used downstream. Compare extents, units, layers, text, dimensions, blocks, hatches and model or paper space.
Format behaviour
What actually happens when DXF is converted to DWG?
DXF is a documented exchange representation for CAD entities; DWG is a compact native drawing format used by AutoCAD and compatible tools. Conversion maps supported lines, arcs, polylines, blocks, layers, text, dimensions and other entities into DWG. Unsupported custom objects, proxy data, xrefs, fonts, plot styles and version-specific metadata may be omitted or represented differently.
What is normally retained
- Supported 2D geometry such as lines, arcs, circles and polylines
- Standard layers, colors and line types where available
- Blocks and inserts supported by the converter
- Basic text, dimensions and hatches where compatible
- Drawing coordinates, extents and unit settings when explicitly defined
What is not retained or may change
- Application-specific proxy or custom objects
- Missing external references, images and underlays
- Fonts, shape files, plot styles or custom line types not embedded in the DXF
- Associativity, constraints and metadata without a DWG equivalent
- Unsupported 3D entities or version-specific features
DXF drawingDXFAutoCAD DWGDWGFormat comparison
DXF versus DWG
Choose the format according to what the next application needs—not because one is universally better.
| Feature | DXF DXF | DWG DWG |
|---|---|---|
| Primary use | Interoperable CAD exchange, CAM and drawing handoff | Native AutoCAD and DWG-compatible drafting workflow |
| Storage | ASCII or binary exchange representation | Compact binary drawing database |
| Entities | Broad documented entity set; support varies by exporter | Rich native entities plus application-specific extensions |
| Dependencies | Can reference fonts, images, line types and xrefs | Can also depend on external assets and plot resources |
| Best source of truth | Useful neutral handoff file | Preferred working file when the team edits and plots in a DWG workflow |
Choose DWG when
The client, supplier or drafting team specifically requires .dwg
The drawing will be edited or plotted in AutoCAD or a DWG-compatible application
You have verified fonts, xrefs, layouts and custom entities after conversion
The target DWG version is accepted by the receiving system
Keep DXF when
The next tool prefers DXF for exchange, CNC or laser workflows
You need a readable neutral handoff rather than a native working file
The DWG conversion drops unsupported objects or dependencies
DXF remains the agreed contractual delivery format
Before continuing
Check the converted DWG before using it
A DWG can open without being visually or functionally identical to the DXF. Compare the drawings before issuing, plotting, machining or editing.
- 01
Verify drawing units and extents
Confirm INSUNITS or the intended scale, then measure known dimensions and compare total drawing extents.
- 02
Compare layers, colors and line types
Check that layer names, visibility, colors, lineweights and custom line types match the source.
- 03
Review text and dimensions
Look for font substitution, reflow, missing symbols, altered dimension styles and broken annotative scaling.
- 04
Inspect blocks and hatches
Confirm block inserts, attributes, dynamic behaviour and hatch boundaries display as required.
- 05
Check model space, layouts and plotting
Verify model-space content, paper-space layouts, viewports, page setups and plot styles if present.
- 06
Resolve external dependencies
Relink xrefs, images, underlays, fonts and support files before final delivery.
Common problems
DXF-to-DWG troubleshooting
Most differences are caused by missing support files, version mismatches, unsupported entities or unit and layout settings—not by the .dwg extension itself.
The DWG opens at the wrong scale
Cause: The DXF unit header is missing, inconsistent or interpreted differently.
Fix: Confirm the intended unit and drawing extents, then set or scale the DWG correctly.Text reflows or symbols are missing
Cause: The target system substituted unavailable SHX or TrueType fonts.
Fix: Install or package the required fonts, or replace them with approved equivalents.External references are missing
Cause: The DXF references files that were not included in the conversion.
Fix: Collect and relink xrefs, images and underlays in the target CAD system.Hatches or line types look different
Cause: Custom patterns or line-type definitions were not available or scaled differently.
Fix: Load the required support files and verify LTSCALE, PSLTSCALE and hatch scale.Some objects disappeared
Cause: Proxy, custom or unsupported 3D entities did not translate.
Fix: Explode or export them to supported primitives in the source application, then convert again.The receiving tool reports an incompatible DWG version
Cause: Its supported DWG release differs from the created file.
Fix: Save or export to a version the recipient confirms, then reopen and validate.Secure processing
Your design files remain yours
Engineering files can contain confidential product geometry and documentation. Marathon OS keeps conversion uploads separate from its public CAD library and explains how each file is handled.
Encrypted transfer
Files are transferred over an encrypted connection.
Automatic deletion
Uploaded source files and converted outputs are automatically deleted within 7 days.
You retain ownership
Uploading or converting a file does not transfer ownership of the design to Marathon OS.
Never published automatically
Conversion files are not listed in the public Marathon OS CAD library.

Frequently asked questions
Frequently asked questions about DXF to DWG conversion
Clear answers about output behaviour, compatibility, pricing, file limits and privacy.
How do I convert DXF to DWG online?
Upload the DXF file (.dxf), confirm DWG as the preselected output, start the conversion and download the DWG result (.dwg). Verify it in the application used for the next workflow.
Why convert DXF to DWG?
Convert DXF to DWG when the receiving team works in AutoCAD or another DWG-based drafting environment and needs a native working container rather than a neutral exchange file.
Will DXF to DWG preserve every drawing element?
Not always. Standard geometry and layers usually transfer more reliably than custom objects, xrefs, fonts, plot styles, dynamic blocks and application-specific metadata. Compare the result with the source drawing.
Which DXF and DWG extensions are supported?
This route accepts .dxf input and creates .dwg output.
Is the DXF to DWG converter free?
Files under 5 MB can be converted and downloaded free. Larger files use one credit for one completed download.
What is the maximum DXF file size?
You can upload a DXF file up to 300 MB. Dense hatches, many blocks, embedded 3D entities and external dependencies can increase processing and review time.
How are my files handled?
Files are transferred securely, are not published to the public CAD library and are automatically deleted within 7 days. You retain ownership of the uploaded design.
