Free DXF to SVG converter
Convert DXF to SVG for cutters, design tools and the web.
Glowforge, Cricut Design Space and many design tools want SVG, not DXF. Drop a DXF and Caddis writes a layered SVG, sized in real millimetres when the file declares its units and is part-sized (up to 3 m across).
Why convert DXF to SVG?
DXF is how CAD and CAM tools exchange 2D geometry, but browser-based cutter software and design apps speak SVG. Converting locally keeps proprietary part drawings off third-party upload sites.
How to convert DXF to SVG
- Choose your DXF (or DWG) file above, or drag it onto the box.
- Check that SVG is selected. You can switch to any other output.
- Select Convert. The file downloads straight away. Nothing is uploaded.
Good to know
- Each DXF layer becomes its own SVG layer, which makes it easy to assign cut, score and engrave operations.
- Check one known dimension after importing. DXF files without declared units ($INSUNITS) can't state their real size.
- Curves become runs of short straight segments, smooth enough for cutting at normal sizes.
What converts, and what doesn't
- Geometry converts as it is drawn: arcs, circles and splines become runs of short straight segments, and blocks and dimensions are exploded into plain lines.
- Text becomes simple single-stroke lettering, so it reads correctly but is no longer editable text. Non-Latin characters may appear as character codes.
- Solid fills are kept. Hatch patterns may be missing.
- Only model space is converted. Paper-space layouts and viewports are not included.
- DWG files from Release 14 through the current AutoCAD 2018 format are supported. 2007-format (AC1021) files are only partially supported: some entities and colours may be missing.
Frequently asked questions
Will the size be correct in Glowforge or Cricut?
When the DXF declares its units and is up to 3 m across, the SVG's width and height are written in millimetres, so it imports at real size. If the DXF is unitless, scale it using a dimension you know.
Are curves kept as true arcs?
No. Arcs and splines are converted to many short straight segments. At normal cutting sizes that is visually smooth.
Is my file uploaded?
No. The file is read and converted by the Caddis engine running inside your browser tab. It is never sent to a server, so confidential drawings stay on your device.
Is it really free?
Yes. There's no account, watermark, page limit or daily quota. The converter runs on your own computer, so it costs us nothing per file.
Need to measure or mark up the drawing too?
The same engine powers the free Caddis viewer on the web and on iPhone. Open DWG, DXF, STEP and STL files, measure, and add markup, all on your device.
