EngravePrep: Laser Photos

Photos ready for the laser. EngravePrep turns an ordinary photo into a precisely sized, monochrome PNG for laser engraving. Choose a material starting point, inspect the actual dots, and export into the laser software you already use. BUILT FOR PHOTO ENGRAVING • Starting points for light wood, dark slate, glass or acrylic, coated metal, and manual workflows • Floyd–Steinberg, Jarvis–Judice–Ninke, Stucki, Atkinson, Bayer, and threshold processing • Exposure, gamma, contrast, black point, white point, and sharpening controls • Inches or millimeters, selectable DPI, exact pixel dimensions, and upscale warnings • Crop, rotate, straighten, before/after comparison, and true 1:1 pixel inspection • Optional on-device background removal with the original preserved • Local saved projects and reusable custom presets • A free six-mode dither test strip for scrap-material testing PRIVATE AND HARDWARE-NEUTRAL Your photos are processed on your device. EngravePrep requires no account, uploads no photos, contains no ads or analytics, and connects to no laser. Export through the iOS share sheet, then import the PNG into LightBurn or another laser workflow that accepts PNG images. TRY BEFORE YOU BUY Use every editing control and inspect your own processed photo for free. Export the bundled sample and a dither test strip without purchasing. A one-time lifetime unlock enables full-resolution exports of personal photos, saved projects, and custom presets. EngravePrep prepares image pixels; it does not provide machine power, speed, frequency, focus, ventilation, or material-safety settings. Always test on scrap and follow your laser manufacturer’s safety instructions. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
