What is the DXF ⇄ SVG Converter?
DXF is the language of CAD and CNC; SVG is the language of vector graphics and laser software. Moving between them usually loses something — curves turn into thousands of straight segments, arcs are mangled, units vanish. This converter parses the real DXF structure (LINE, CIRCLE, ARC, LWPOLYLINE and POLYLINE with bulge arcs, ELLIPSE, SPLINE evaluated as NURBS, TEXT/MTEXT, and INSERT blocks with scale, rotation and arrays) and writes SVG that keeps circles as circles and arcs as arcs, grouped by layer at true millimetre scale.
Going the other way, SVG paths (M, L, H, V, C, S, Q, T, A and relative variants), rectangles with rounded corners, circles, ellipses, polylines, polygons, groups and transforms are flattened to a precision you choose and written as DXF in AutoCAD 2000 or R12 format with a proper layer table and units header. DXF has no units unless the file says so, so a Units selector lets you fix the classic 25.4× size mistake and the preview shows the real dimensions before you download.
3 steps to your result
Open the tool and follow along. Nothing to install.
What you get
Arcs, circles, bulged polylines, ellipses, splines, text and nested blocks — not just lines.
Reads $INSUNITS, lets you override, and always shows size in mm and inches.
DXF layers become SVG groups; SVG groups/ids become DXF layers.
True-scale SVG and standards-correct DXF (R2000 or R12) that opens in LightBurn, Inkscape, Fusion, Onshape and QCAD.
AZRS tools are free to open and use.
It opens in your browser, so there is nothing to download.

Questions people ask
Does it keep layers?
Yes — DXF layers become SVG groups and the reverse.
Which DXF versions can it read and write?
It reads ASCII DXF of any version (not binary) and writes AutoCAD 2000 (AC1015) or R12 (AC1009).
Are splines supported?
Yes — NURBS splines are evaluated; splines with only fit points use a smooth interpolation.
Is my file uploaded?
No — conversion runs entirely in your browser.
How do I use the DXF ⇄ SVG Converter?
1. Drop in a .dxf or .svg file. 2. Check the size, layers and preview; fix units if the size looks wrong. 3. Optionally join touching segments and move the drawing to the origin. 4. Download the converted file.
