Check for Legal Permission : It is legal to remove a password from a PDF only if you have legal permission to do so. Unlawfully removing a password can be both unethical and illegal.
Use Google Chrome to Unblock Quickly : Access the PDF document in Chrome. Type the password, then select Print, and then Save as PDF. The new document will be saved as a PDF file without a password.
Use Adobe Acrobat Pro (Paid Option) : To unlock the file in Adobe Acrobat Pro, Open the locked PDF file. Enter the password. Choose File > Properties > Security tab > No Security.
Use Free Online Tools (With Caution) : Want to unlock PDFs online? Sites like Smallpdf and iLovePDF can unlock your PDFs with a few clicks, and the file does not contain any confidential or personal data before being uploaded to the cloud.
Desktop Software for Bulk Unlocking : There are tools, such as PDFCrack or PDF Unlocker (both free and paid), that allow you to bulk unlock multiple files in a single batch process — very useful for offices or heavy users.
Always Secure the New Unlocked File : After unlocking the PDF, ensure that you securely save the new PDF to your computer. In addition, you may want to add file protection if it is warranted, or simply store it in a new folder.
