What Stirling-PDF actually does
Stirling-PDF is a self-hosted web application designed for processing PDF documents. It provides an interface for common document workflows including merging, splitting, file conversions and optical character recognition.
Best fit: It is well-suited for users who need a centralised tool for document manipulation without relying on external cloud-based services.
Worth knowing: The resource footprint of a Java-based web application can be heavier than native alternatives, requiring adequate memory allocation on your server.
Deployment notes
Deployment is typically handled via Docker, requiring persistent storage volumes for temporary file processing and a reverse proxy to manage HTTPS.
