Guides
Short, practical answers about LightBurn project files. Each guide has the viewer at the top, so you can try it on your own file as you read.
- Open without LightBurnSee the design, layers, speed, power and size inside a LightBurn .lbrn2 or .lbrn file without installing LightBurn. Nothing is uploaded.
- LBRN2 to SVGTurn a LightBurn .lbrn2 or .lbrn project into an SVG in your browser. Layers become groups in LightBurn's colours, sizes stay in millimetres, and nothing is uploaded.
- LBRN2 to DXFExport a LightBurn .lbrn2 or .lbrn project as an R12 DXF in your browser: one DXF layer per LightBurn layer, millimetre units, true circles. Nothing is uploaded.
- LBRN2 for xToolGot a .lbrn2 design but use xTool Creative Space? Convert it to SVG in your browser, keep the layer colours, and read the original speed and power settings.
- LBRN2 for GlowforgeThe Glowforge app takes SVG, not LightBurn files. Convert a .lbrn2 to SVG in your browser, with each LightBurn layer in its own colour so it becomes its own print step.
- Layers, speed and powerA plain guide to what a .lbrn2 file stores: layers and modes, speed in mm/s, power, passes, line interval, run order, embedded images and notes, and what it leaves out.
- .lbrn vs .lbrn2LightBurn saves projects as .lbrn2 by default and .lbrn as its legacy format. What differs inside, which to use, and how to open either without LightBurn.
- Layer coloursAll 32 LightBurn layer colours, C00 to C29 plus tool layers T1 and T2, with hex and RGB values, so your SVG and DXF designs land on the right layers.
- The .lbrn2 formatHow a LightBurn .lbrn2 project is structured: the XML root, cut settings, shape types, the XForm matrix, the VertList and PrimList path encoding, and embedded bitmaps.
