All-in-one PDF manipulation tool with a clean web UI. Merge, split, convert, OCR, sign - all self-hosted and private.
What is Stirling PDF?
Stirling PDF is a powerful, open-source PDF manipulation tool with over 75,000 GitHub stars. It provides a clean web interface for every PDF operation you can think of - merging, splitting, rotating, converting, OCR, digital signatures, and dozens more.
Unlike cloud-based PDF tools (Adobe Acrobat, Smallpdf, iLovePDF), Stirling PDF runs entirely on your own server. Your documents never leave your infrastructure. No file size limits, no watermarks, no per-page charges, and complete privacy for sensitive documents.
Why Stirling PDF?
