Built with open source.

The scanner bundles its processing dependencies locally.

• OpenCV 4.12.0 — Apache License 2.0. Custom WASM exports: document detection and perspective correction. License. Source and build instructions are described in the project’s scripts/build_opencv.py and scripts/scanner.cpp.
• heic-to 1.6.6 and its libheif decoder — LGPL-3.0. License, source and rebuilding information. This separate JavaScript worker is loaded only for HEIC images that need conversion.
• pdf-lib — MIT. Lucide icons — ISC. Astro — MIT. Svelte — MIT.

OpenCV and HEIC decoder assets can be replaced by compatible builds without changing document files. Full dependency licenses are included in the local source distribution.
