Stirling PDF
Your locally hosted one-stop-shop for all your PDF needs
A comprehensive PDF toolkit that processes everything in your browser. Merge, split, compress, convert PDFs and more without uploading your files to any server.
What we love ❤️
- Processes PDFs locally - your files never leave your device
- Multiple PDF operations available in one place
- Clean interface without unnecessary elements
- Open source and actively maintained
- No file size limits since processing is local
Worth noting 💡
- Some operations might be slow on less powerful devices
- Interface prioritizes functionality over aesthetics
- Requires modern browser for all features
- Requires technical setup (Docker) for self-hosting.
StirlingPDF brings professional PDF operations right to your browser while respecting your privacy with local processing. It provides essential PDF tools without the common limitations of online alternatives. The local processing approach makes it particularly valuable for handling sensitive documents.
