KkFileView

kkFileView is a Spring Boot-based file preview server that provides a universal document viewer for rendering office files, PDFs, images, and 3D models directly in a web browser. It functions as a secure document rendering service that allows users to view a wide variety of file formats without requiring local software installations.

The project distinguishes itself through specialized CAD to SVG conversion, transforming complex drawings into web-compatible formats. It includes a RESTful file preview API that allows these rendering capabilities to be integrated into external business applications via standard HTTP calls.

The service manages secure document access through basic authentication, encrypted file decryption for password-protected documents, and upload risk filtering using a configurable blacklist. Its operational surface includes disk-based conversion caching and automated preview cache management to optimize performance.
