The short answer
For a few photos without installing anything, ImagR is quick. On Windows with a one-time budget, Laser Photo Wizard and PhotoGrav prepare photos offline. If you already own LightBurn, its image modes work for simple jobs. If photos are a daily part of your work, Vextrify prepares them on your own computer with material profiles, repeats the same recipe across a batch, and in the desktop app sends the result straight to the laser.
