How to convert a DXF to SVG
Add your DXF
Drop a DXF onto the tool, or click to choose one. It is read in your browser and never uploaded.
Check the preview
Zoom the preview and switch off any layers you do not want in the output.
Download SVG
Click Download SVG. DWG, PDF, STL are one click away from the same file.
What happens to your file
The DXF is read as geometry, arcs and splines are flattened to a fine tolerance, and the result is written as an SVG sized in real millimetres with one group per layer, so Inkscape and Illustrator show the layers and the artwork lands at the right size.
Whatever cannot be converted is listed under the preview by type and count, so a drawing with 3D solids or an external reference tells you so instead of coming out quietly incomplete. Need a photo or scan turned into a drawing instead? That is the image to DXF converter and the AI drawing generator.
About formats
DXF (Drawing Exchange Format) is a CAD data file format developed by Autodesk, first released in December 1982 with AutoCAD 1.0 to enable interoperability between AutoCAD and other programs. The format exists in two variants: ASCII DXF, a human readable text file organised into sections (HEADER, TABLES, BLOCKS, ENTITIES, OBJECTS), and binary DXF for faster parsing. Each geometric entity, including lines, arcs, circles, polylines, splines, text, dimensions and 3D solids, is described by group codes paired with values that specify coordinates and properties. DXF versions evolve alongside AutoCAD releases, adding support for new features with each edition. One major advantage is universal CAD compatibility, since DXF is supported by virtually every CAD, CAM and engineering application across all platforms, which makes it the most widely accepted exchange format for technical drawings. The ASCII variant is another strength, because drawings can be inspected, debugged and generated programmatically with text tools or scripts. DXF serves as a critical bridge that lets architects, engineers and manufacturers share precise drawings regardless of which software each party uses, and it remains the standard for cross platform CAD data exchange.

Frequently asked questions
Is DXF to SVG conversion free?
Yes, with no watermark and no file limit. Everything runs in your browser, so the file never leaves your computer; a free account is needed only to download a converted file. Viewing needs no account at all.
Is my DXF uploaded anywhere?
No. The file is opened by JavaScript running in your browser tab and never sent to a server. You can disconnect from the internet after the page loads and the tool keeps working. That is the main reason to prefer this over an upload-and-email converter for a drawing you are not allowed to share.
Which DXF files open?
ASCII and binary DXF from R12 to 2018 and later. R12 files with old-style POLYLINE entities are handled, and closed polylines are kept closed, which matters for cutting and for STL.
What size is the SVG?
Real size. The SVG is written with width and height in millimetres and a matching viewBox, so Inkscape, Illustrator, LightBurn and a browser all open it at the drawing's true dimensions rather than at some pixel guess.
Are layers preserved?
Yes, as groups. Each layer becomes a <g> with the layer name, marked so Inkscape shows it as a layer. Arcs, circles, ellipses and splines are flattened to short straight segments at a fine tolerance; text is written as <text> elements.
What is not converted?
3D solids, surfaces, meshes and regions (ACIS data), raster images, PDF underlays, OLE objects, external references, and paper-space layouts. Tables, multileaders and tolerances are read but not drawn. Whatever was skipped is listed under the preview after the file opens, by entity type and count, so nothing disappears silently.
I have a DWG or SVG instead. Can I still use this?
Yes. The converter on every one of these pages accepts DXF, DWG and SVG, whichever page you started from, and offers every output it can produce from that file.
Is there an API for DXF to SVG?
Not for this tool yet. The converter runs entirely client-side. The REST API, command line tool and MCP server currently cover image to DXF, DWG and STL; if you need vector conversion in a pipeline, say so at the contact page and it moves up the list.
