Engine architecture

No paid API requirement.

Browser-native tools use PDF-lib, PDF.js, Canvas, and JSZip. Heavy modules such as Office conversion, OCR, repair, encryption, and advanced text reconstruction are routed to free self-hosted workers such as LibreOffice, Ghostscript, qpdf, Poppler, Tesseract, and ImageMagick when installed on the VPS.
