Open LBRN2 files in your browser
The project LightBurn saves a laser job in: its layers and their settings, and every shape on the bed. Open one right here and see what it will cut. Nothing leaves your device.
Or drop it anywhere on this page
What you'll see
Your job opens as the laser will run it, each layer in its color on a white ground, with its layers and their settings in the panel beside it.
- Every cut, line and fill in its layer's color
- Layers • Speed, power and passes • Hide one or show it alone
- Measure in millimeters • Its size, origin and material
- Export • DXF, SVG, PDF at real size and PNG
About LBRN2
LightBurn is the app many diode and CO2 laser owners run their machines with, on Windows, macOS and Linux. It saves a job as an LBRN2, XML that keeps each layer's cut settings (its mode, speed, power, passes and fill interval) and every shape: rectangles, ellipses, paths of lines and curves, text with its outline, groups and pictures to engrave. LightBurn 0.9.21 brought LBRN2 in 2021, and older versions save LBRN, the same with its points written one by one.
Only LightBurn opens one, and it needs a license once its trial ends. Nothing built into Windows, macOS or phones shows a project's shapes.
Filepeek draws the job in your browser on a white ground, each layer in LightBurn's color, its fills shaded and its pictures where they'll be engraved, at its real size in millimeters. The panel lists the layers with their mode, speed, power and passes, and those that never run. Measure between two points, see the material and origin in Show details, and export it as DXF for another laser app, SVG, PDF at its real size or PNG.

Questions
Can I open a LightBurn file without LightBurn?
Yes. Drop it on this page to see every layer and shape with each layer's settings, and save it as DXF or SVG to open it in another laser app.
Why is some text missing?
LightBurn keeps each text's outline beside it, and Filepeek draws that outline. Text saved without one is left out, and Show details counts it.
What do the layers' colors mean?
LightBurn gives each layer one of its 30 colors, C00 to C29, and two tool layers, T1 and T2, which never run. Filepeek shows each in its color with the name you gave it.
Is the power in watts?
No. Power is a percent of the laser's most, from its least at corners to its most along a line, and speed is in millimeters a second, as LightBurn shows them.
