Setting and Removing PDF Passwords: The Complete Guide to Document Security
Learn how to set PDF passwords to protect important personal info and confidential documents, and how to remove them when no longer needed.
When sending documents containing important content like resumes, pay stubs, or confidential contracts via email or messenger, locking the PDF file with a password is no longer an option, it's a necessity.
We comprehensively summarize how to set a PDF password to ensure document security, and conversely, how to remove the password when you have the rights to the document but find it tedious to enter the password every time.
Why You Should Set Passwords on PDFs
- Preventing Personal Data Leaks: Prevents documents containing social security numbers, contact info, or bank copies from unintentionally leaking to third parties.
- Restricting Access to Confidential Documents: Restricts viewing to only authorized personnel when transmitting internal company reports or financial statements.
- Regulatory Compliance: In certain industries, encrypting customer data before transmission is mandatory.
1. Setting a Password on a PDF Document (Encryption)
The process of locking a document for protection is surprisingly simple.
- Open the Tool: Open a trusted online PDF password tool.
- Upload the File: Upload the PDF document you want to protect.
- Enter a Password: Type the password you want to use for opening the document twice to confirm. (The longer and more varied with upper/lowercase letters, numbers, and symbols, the safer it is.)
- Encrypt & Download: Click the
Setbutton to encrypt the document. Download the encrypted version and attach it to your email. It's best to share the password with the recipient through a separate, secure channel like a messenger.
2. Permanently Removing a PDF Password (Decryption)
If it's a monthly pay stub you receive or an encrypted document you created yourself, it can be annoying to type a long password every time you open it. In this case, it's convenient to remove the password and save the file.
(※ Note: This method is only possible if you already know the password. It is not a feature for forcibly hacking someone else's document.)
- Open the Tool: Open an online PDF unlock tool.
- Upload the File: Upload the locked PDF file.
- Enter the Password: Enter the current password to verify you are the legitimate owner of the document.
- Unlock & Download: Once authenticated, you can download the original document with the password permanently removed. You can now open the document with a single click.
