Additional information




There are no refunds on software. Please download and test the trial version before making a purchase.

Minimum System Requirements

LightBurn will run on Windows 7.0 or later, 32 or 64 bit, MacOS 10.11 or later, or 64 bit Linux (Ubuntu 16+ or Fedora 28+, anything else may not work as intended).

LightBurn does not require a powerful computer for most work, though if your designs contain a lot of images, more memory is helpful., and a faster computer will make it easier to work with large images or complex vector graphics.
