About
ShapeScan is a tool designed to convert photos of objects placed on A4 or US Letter paper into true-scale SVG files. It is specifically tailored for workflows involving laser cutting, CNC machining, and CAD design. The tool operates with precision, offering 1mm accuracy through marker-based calibration and AI-assisted segmentation. Users can upload photos from any smartphone, which are then auto-traced and downloaded in formats suitable for various fabrication processes, including SVG, DXF, PNG, and STL. ShapeScan is browser-based, requiring no special equipment, and supports both millimeter and inch measurements. It is free to use for personal and commercial projects, providing robust privacy measures. The platform continuously improves and offers optional user support through donations. ShapeScan is a practical solution for makers, engineers, and fabricators looking to digitize hand-drawn designs or physical objects quickly and accurately.
