Frequently asked questions
Can I unlock a PDF without its password?
This tool is for documents you are authorized to access; provide the correct password where required. It is not a password-recovery service.
Does unlocking remove page content?
No. It removes password protection and saves a PDF with the same intended content.
Should I share the unlocked copy?
Only with authorized recipients. The output no longer has the original opening-password barrier.
Can I password-protect the result again?
Yes. Use Protect PDF to apply a new opening password.
What are the limits and privacy policy?
Guests can upload files up to 25 MB each. A free account raises the limit to 50 MB per file, and Premium allows 500 MB per file with larger batches.
