Security – PDF HUB

Zero server processing, automatic memory wipe, HTTPS encryption. Discover why PDF HUB is one of the safest PDF tools online.

Last Updated: November 20, 2025

Your files and your privacy are our highest priority. Here’s exactly how PDF HUB keeps everything secure:

1. Zero Server-Side Processing

  • Every single operation (merge, compress, add page numbers, rotate, unlock, etc.) happens only in your browser.
  • Your PDF never leaves your device — not even for a millisecond.
  • There is literally nothing for hackers to steal from our servers because your files never reach us.

2. No File Uploads Whatsoever

  • We do not have any upload buttons that send files to the server.
  • All processing is done using client-side JavaScript libraries (PDF.js, etc.) inside your own computer or phone.

3. Automatic Memory Wipe

  • As soon as you close the tab, refresh the page, or finish your task, the file is instantly removed from your browser’s memory.
  • No temporary files are saved on your device.

4. Encrypted In-Browser Processing

  • All tools run in a secure sandboxed environment inside your browser.
  • Even if someone somehow intercepted your internet traffic, they would only see encrypted data and code — never your actual PDF.

5. HTTPS Everywhere

  • The entire website is served over HTTPS with strong TLS encryption.
  • This protects the code and libraries we send to your browser from being tampered with.

6. No Third-Party Risk

  • We do not load scripts from advertising networks, social media, or unknown sources.
  • Only trusted, open-source libraries are used (regularly updated and audited).

7. Regular Security Updates

  • All libraries we use are automatically kept up-to-date.
  • Our code is reviewed frequently for any potential vulnerabilities.

8. Bug Bounty & Responsible Disclosure

Found something that worries you? We take security seriously. Email us at: security@pdfhub.com We respond fast and reward valid reports.

Bottom Line

Because your files never touch our servers, PDF HUB is one of the safest ways on the internet to work with sensitive PDFs — whether they contain personal data, financial documents, legal contracts, or medical records.

You stay in full control. Always.
