Privacy by Design

Your Files Never Leave Your Device

Unlike other PDF tools, PDFox processes everything locally in your browser. Open from Google Drive or your device. Process locally. Your files never touch our servers.

Our Privacy Principles

100% Client-Side Processing

All PDF editing, text extraction, OCR, and rendering happens directly in your browser using JavaScript and WebAssembly. Zero server involvement.

Your Files, Your Cloud

Open PDFs from Google Drive or your device. Everything processes in your browser — files never transfer to our servers. Your cloud, your control.

No Data Retention

Close the tab and your work is gone from memory. We have nothing to retain, nothing to breach, nothing to hand over.

How We're Different

Most PDF tools upload your files to their servers. We don't.

Other PDF Tools

  • Upload your files to remote servers
  • Store and process documents in the cloud
  • Retain files for days, weeks, or indefinitely
  • Vulnerable to data breaches and leaks
  • May use your data for AI training

PDFox

  • Process everything in your browser
  • Files never leave your device
  • Zero data retention - nothing to breach
  • Immune to server-side attacks
  • Your documents are never used for anything
