What does SafePDF Protect Method do?

SafePDF Protect ensures your documents remain secure, authentic, and tamper-evident. Our method includes:

1. Prevent Copying
   Make the text and content of your PDF unable to copy or extract, protecting your intellectual property.

2. Seal the PDF File
   Apply a unique digital mark that includes:

   • A timestamp of when the file was sealed

   • A brand seal that protects your work 

   • A unique file identifier or hash that guarantees that any change has been done

3. Guarantee Integrity
   Any attempt to alter the file after sealing it will invalidate the hash, letting recipients instantly verify its authenticity.

4. Easy Verification
   Recipients can check the PDF’s seal with SafePDF Verify Method to confirm that the document is genuine and untampered.
