What it finds before your laser does
Open contours
Shapes that do not close. Loose ends are marked red, because that part will not drop out.
Duplicate lines
The same line drawn twice is cut twice and burns the edge.
Text
Most laser programs skip text entities. Convert them to outlines first.
Real size
Width and height in millimetres and inches, so a part in inches is not cut 25 times too small.
Cut length
Total path length and the cutting time at the speed you set.

Open your DXF
Drop the file on the page. It is read in your browser, nothing is uploaded.

Save as SVG
Click Save as SVG. The file is made on your computer in a second.
Questions
Is the SVG to scale?
Yes. The SVG's width and height are written in millimetres, so it imports at the size of the DXF.
Is my DXF uploaded anywhere?
No. The viewer, the check and the SVG, PDF and PNG exports all run in your browser; the DXF file never leaves your computer.
Which DXF files open?
ASCII DXF from AutoCAD R12 to 2018 and from LibreCAD, QCAD, Fusion 360, SolidWorks, Inkscape, LightBurn and other programs: lines, arcs, circles, polylines, splines, ellipses, text, dimensions, hatches, blocks and layers. Binary DXF and DWG are not supported yet.
Is it free?
Yes. Every converter, the viewer and the generators are free, with no sign-up and no watermark.
