Frequently Asked Questions
Why does the tool say my PDF is 'encrypted' even though it opens without a password?
Some PDFs use empty-password encryption u2014 meaning they're encrypted but with no actual password required. This is common with Acrobat's 'permissions-only' protection. The flag is still set, even though opening succeeds silently.
What does PDF version really mean?
It identifies which PDF specification the file uses. PDF 1.4 was widely supported by 2001. PDF 1.7 (2006) and PDF 2.0 (2017) added newer features. For maximum compatibility, save as PDF 1.4 or 1.5. Modern viewers handle all versions.
Why is creation date sometimes wildly inaccurate?
PDFs only carry the date their producing software wrote into them. If the original document was edited or re-saved, the date may reflect that, not when the original content was authored. Don't trust PDF dates for legal proof of authorship.
