Convert DXF drawings to STL free in your browser. Closed outlines become editable 3D extrudes at the drawing’s own units, ready to export and print.
Drag your .dxf file into OwlCAD in your browser, choose an extrude depth and whether the shapes become one object, then click Export and save it as STL. There is nothing to install.
Laser, CNC and CAD drawings extrude into solids you can still edit.
Lines and arcs that meet end to end are chained into closed loops, and blocks are expanded, so a real-world drawing imports whole.
A part drawn in inches arrives at the right size in millimetres. A drawing with no units is read as millimetres, and OwlCAD tells you so.
Set any thickness, add holes or a base, and combine the part with other shapes before you export.
Drop the drawing on the build plate, choose a thickness, and export an STL for your slicer.
It opens on your device, it is saved to your workspace as you work, and it exports back out in the format your slicer wants.
Your browser reads and renders the model itself, so it appears as soon as you drop it in — you are never queued behind anyone else’s upload, and the file does not travel anywhere before you can see it.
Most online viewers forget your file the moment you close the tab. OwlCAD keeps the model in your own workspace and syncs it as you work, so it is still there when you come back to this browser. Create a free account and it follows you to any device, and your projects dashboard lets you delete anything you no longer want.
When you are done, export STL, 3MF, OBJ, GLB or STEP — the format your slicer or your colleague actually needs, not a project file that only opens here.
Closed outlines. Lines, polylines, arcs, circles, ellipses and splines are read, lines that meet end to end are joined into loops, and block references are expanded. Open lines that never close, text and dimensions have no area to extrude, so they are left out.
The drawing’s own units, so a part drawn in inches arrives at the right size. A drawing that declares no units is read as millimetres, and OwlCAD says so when it imports, in case it was drawn in inches.
Yes. A flat part, sign or template from a laser or CNC drawing extrudes to any thickness, and you can add holes, fillets or a base before you export STL or 3MF.
Yes. Importing, editing and exporting in OwlCAD is free, and you can start without an account. AI generation is the optional Pro upgrade.
