How to Unlock a Secure PDF File. There are two types of secure PDFs: user-locked, which means you need a password to view the contents, and owner-locked, which means you need a password to copy, print, or otherwise modify the PDF’s contents. While unlocking how to unlock the pdf file without password user-locked PDF without the password is impossible without purchasing software, you can unlock an owner-locked PDF in a few ways. If you aren’t already logged into your Google account, you’ll need to do so now with your Gmail address and password.
Click and drag your PDF into Google Drive. This will open the “Print” screen. If the PDF is user-locked, you’ll need to enter the password and then use the Print shortcut again. This option should be beneath the “Destination” heading on the left side of your screen. This option is under the “Local Options” heading in the “Select a Destination” window. It’s in the top left corner of this screen.
Doing so should download the PDF to your computer as an unsecure file. You may have to select a save location before your file properly downloads. This is in the top left corner of the screen. Look at the “Security Method” line. It should say “No Security”, thereby proving that your PDF is no longer locked. This is at the top of the Properties window.
Open the Adobe Acrobat program. This must be the “Pro” version, not the “Reader” version. Otherwise, you won’t be able to remove the password. This option is in the top left corner of the screen. Alternatively, if your PDF reader has a “Recently Viewed” tab, you can check there to see if the PDF you need is displayed. If you elected to look for the PDF in the “Recently Viewed” section, skip this step.
Double-click the PDF you wish to open. It’s on the left side of the screen beneath the “Home” tab. If your PDF is user-locked, you’ll need to enter the password here first. This is a link below the “Security Settings” heading.
It will say something like “Password Security”. This should be an option in the drop-down menu that appears. Type in the PDF’s password. As long as your password was correct, your PDF will no longer have a password lock on it. If your file is eligible for unlocking, PDFUnlock will do so and then automatically download the unlocked PDF to your computer.
You should now be able to edit the PDF’s information. You’ll do this by double-clicking a setup file and then following the on-screen instructions. You’ll need to install Ghostscript first since the GSView program runs using Ghostscript’s code. Click and drag the secure PDF into the GSView window. If your document is user-locked, GSView won’t be able to access its information.
