Key differences
Zero setup
Open a web page and go. No Docker, no Java, no server to stand up or keep running. Stirling needs all of that before you can do a single task.
Private without hosting
pdf2kit is local on every visit. Stirling is only private on your own instance - its convenient public demo uploads your files to Stirling's server.
Focused, not vast
pdf2kit does the common page jobs cleanly. Stirling does far more, which is powerful but heavier than most people need for a quick merge or rotate.

Choose pdf2kit if you want to
- Merge, split, reorder, rotate or delete pages fast
- Keep files on your device with nothing to host
- Skip Docker, servers and maintenance entirely

Choose Stirling PDF if you want to
- Run a self-hosted suite with 50-plus tools
- Use OCR, conversions, redaction or signing
- Edit the text inside a PDF (version 2.0)

Common questions
Do I need a server to use pdf2kit?
No. pdf2kit opens in a web page and runs on your device. Stirling PDF is self-hosted, so you run it on your own server with Docker or Java before you can use it.
Which one is more private?
Both keep files local when used properly. pdf2kit never uploads. Stirling is private only on your own self-hosted instance; its public demo server does receive uploads, so avoid the demo for sensitive files.
Does pdf2kit have as many tools as Stirling?
No. Stirling has 50-plus tools, including OCR, conversions, redaction and, since version 2.0, text editing. pdf2kit focuses on the common page tasks and does them without any setup.
Is Stirling PDF free?
Yes, it is free and open source to self-host, with a paid tier for large organizations that adds sign-in, user management and support. pdf2kit is free too, with nothing to host.
