PRIVATE AND HARDWARE-NEUTRAL
Your photos are processed on your device. EngravePrep requires no account, uploads no photos, contains no ads, and connects to no laser. RevenueCat provides anonymous purchase and revenue reporting; artwork and editor activity stay on your device. Export through the iOS share sheet, then import the PNG into your existing laser workflow.
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.

Fixed a sizing issue that prevented clearing the width field on iPad. You can now replace the width and enter decimal values more easily.
