The short answer
If you want a one-time purchase on Windows for much less, look at Laser Photo Wizard at $99.95. For a few photos without installing anything, ImagR works in the browser. If you already own LightBurn, try its image modes before buying anything. If photos are regular work and you want to go from photo to laser in one program, on a Mac, Windows or Linux, use Vextrify.
- Cheaper one-time on Windows → Laser Photo Wizard
- A few photos in the browser → ImagR
- Already own LightBurn → its image modes
- Regular photos, straight to the laser → Vextrify
