How your documents stay private
No server, no upload, no storage
Privacy through architecture
PDFHarbor does not have a file processing server. Every tool runs as client-side JavaScript in your browser tab. Your documents never leave your device.
Architecture
What this means in practice
Documents stay in browser memory
Files exist only in your browser's RAM while you use the tool. Close the tab and the data is gone.
No account or personal data needed
You don't need to sign up or provide any information to use any tool.
Built on open-source libraries
PDF.js (Mozilla), pdf-lib, and Tesseract.js — all widely audited, all running in-browser.

What we do collect
Your documents are private. The website itself uses standard web infrastructure:
- Anonymous page-view analytics (pages visited, device type)
- Ad-related cookies set by Google AdSense
- HTTPS encryption on all connections
None of this interacts with your files. For full details, see our privacy policy.
