PDFox runs entirely in your browser — your files never leave your device. Our architecture is built on privacy-first principles, backed by industry-standard security.
All PDF processing — parsing, decompression, decryption, rendering, editing, and serialization — executes exclusively within the user's browser. This is not a policy choice — it's how the patent-pending DNPR engine is architecturally designed.
Powered by DNPR — proprietary PDF 2.0 interpreter (patent pending) — all operations run entirely in your browser. No document data is ever transmitted to any server.
The PDFox website and application delivery are protected by:
Strict authentication and authorization:
Meeting regulatory requirements:
Your files never reach our servers:
24/7 security operations:
Your documents live on your machine. We never receive, sell, share, or use your files for any purpose.
PDFox processes everything in your browser. We never see your files, so there is nothing for us to access, decrypt, or hand over.
We clearly disclose how we process your data. No hidden tracking or unexpected usage.
