The Hidden Cost of "Free" PDF Tools

Every day, millions of people upload sensitive documents to free PDF tools online. Tax returns, contracts, medical records, passport copies - all sent to unknown servers.

What happens to your files?

Most services:

  • Store files "temporarily" (hours to days)
  • May scan content for analytics or advertising
  • Could be subject to government requests
  • Might suffer data breaches
  • The Privacy-First Alternative

    What if your documents never left your computer? That's exactly how ExactPDF works.

    How Local Processing Works

  • You select a file using your browser's secure file picker
  • JavaScript processes the file in your device's memory
  • The result downloads directly to your device
  • Nothing is transmitted over the network
  • A Privacy Audit of Common PDF Tasks

    Compressing PDFs

    Online tools: Upload → Server processing → Download ExactPDF: Select → Local compression → Save

    Merging PDFs

    Online tools: Upload multiple files → Server merging → Download ExactPDF: Select files → Browser merging → Save

    OCR / Text Extraction

    Online tools: Upload → Cloud AI processing → Download ExactPDF: Select → Local Tesseract.js → Save

    For Privacy-Conscious Users

    Who Should Care?

  • Legal professionals - Client confidentiality is paramount
  • Healthcare workers - HIPAA compliance matters
  • Financial advisors - Protect client financial data
  • Government employees - Sensitive government documents
  • Anyone with private documents - We all have something worth protecting
  • The Swiss Standard

    Switzerland is known for its strict privacy laws. Swiss banks, Swiss data protection - it's a global standard. ExactPDF meets this standard by simply never collecting your data in the first place.

    Practical Privacy Tips

    1. Check Network Activity

    Before using any PDF tool, open Developer Tools (F12) and watch the Network tab. If files are uploaded, find an alternative.

    2. Test Offline Mode

    Disconnect from the internet and try the tool. If it works offline, it's processing locally.

    3. Read Privacy Policies

    Look for clear statements about:
  • No file uploads
  • No data collection
  • No third-party sharing
  • 4. Prefer Open Source

    Open-source tools can be audited. ExactPDF uses open-source libraries like pdf-lib and Tesseract.js.

    The ExactPDF Promise

  • 100% Browser-Based - JavaScript does all the work
  • Zero Uploads - We can't see what we don't receive
  • Works Offline - The ultimate privacy test
  • Free Forever - No premium tier that might compromise privacy
  • Beyond PDF Tools

    The same principles apply to all document processing:

  • Image editors
  • Format converters
  • File compressors
  • Text extractors
  • Always ask: Does my file leave my device?

    Conclusion

    Privacy isn't about having something to hide - it's about having the right to choose who sees your information. Choose tools that respect that right by design.
