Overview
Stirling-PDF is a comprehensive, self-hosted PDF manipulation tool that provides 50+ operations in a clean web interface.

It runs as a Docker container and processes all files locally, ensuring document privacy. The tool supports batch operations, drag-and-drop file uploads, and a pipeline feature that chains multiple operations.
