## What it is
Stirling PDF is an open-source, self-hostable PDF platform offering 50-60+ tools for editing, merging, splitting, signing, redacting, converting, OCR, and compressing PDFs via a web UI, desktop app, and REST API. It runs in Docker or on your own servers so documents never leave your infrastructure, with pipeline automation for batch processing.

## Use cases
- merge and split pdf files
- ocr scanned pdf documents
- redact sensitive info from pdfs
- convert pdfs to other formats
- sign pdf documents
- batch process thousands of pdfs with pipelines
- self-hosted pdf editor for privacy
- compress large pdf files

## When to choose
- you need a private, self-hosted alternative to online PDF tools
- you want to automate PDF workflows via REST API or no-code pipelines
- you handle sensitive documents that must not leave your servers
- you need a wide range of PDF operations in one tool
- you want enterprise features like SSO and audit logs

## When to avoid
- you only need a lightweight command-line PDF utility
- you want a fully free hosted service without self-hosting
- you need deep PDF form-filling or design features of commercial editors
- you cannot run Docker or a Java server
