COMMON QUESTIONS

Frequently Asked Questions

PDF security settings, owner passwords & decryption safety decoded
? How does the PDF unlocker tool work?
It uses the owner password to decrypt document binary nodes, re-compiling standard PDF structures without encryption dictionaries.
? Are my private PDF documents or typed passwords loaded onto external servers?
No. All stream decryptions, signature verifications, and dictionary rebuilds are computed locally in browser memory.
? Can the tool unlock a PDF if I do not know the password?
No. You must know the password to decrypt the file streams. The tool does not perform password cracking.
? Will unlocking a PDF affect digital signatures?
Removing passwords alters the document hash structure, which will invalidate any existing digital signatures.
? What is the difference between User and Owner passwords?
User passwords prevent opening the file. Owner passwords restrict page editing, text copying, and print permissions.
? Does it support both Acrobat 9 and newer version files?
Yes, it handles classic RC4 encryption as well as modern PDF 2.0 standard AES-256 permission schemes.
