Each tool runs in your browser. Your photo and your pattern never leave this page.
Photo metadata
See where a photo says you took it, then strip it.
Drop a photo and read its GPS location, camera, date and owner fields. Save a clean copy with none of them.
Pattern strengthTest how long your pattern holds against guessing.
Draw a pattern on a 5 × 5 grid and see how many patterns share its length, which shapes thieves try first, and how long a full search takes.
