Password Protect Your Existing PDF Documents for Free In Windows

 
 
In this post I am going to tell you how to password protect an already existing PDF file for free unlike the last post where I showed you how to password protect a Microsoft Office document by converting it into a PDF file (Read by clicking here).

Note that once you encrypt the document you will not be able to recover the document if you forget the password. If you forget the password, we at PC Seekers take no responsibility and won't be able to help you in any way.

If you wish to password protect your PDF with free third party tools and not want to submit a payment method for the free trial then please do scroll down to Password Protect PDF with 3rd Party tools.

Password Protect PDF With Adobe Acrobat:

  1. Download Adobe Acrobat Reader from here.
  2. Open your PDF in Adobe Acrobat.
  3. Click on 'File' and select 'Password Protect' or 'Protect Using Password'. Alternatively you can click on 'Edit' --> 'Tools' --> 'Protect' --> 'Protect using Password'.
  4. If you are already a paid customer of Adobe then just login into your account. If you're not a paid customer then go the Adobe Acrobat Pro DC page and click on 'Free Trail' button. Then you need to enter your Email, Password, Name and a payment method so that Adobe be charge you once the trial period ends - do remember to cancel the subscription before the indicated date if you don't wish to be charged for it. If you are asked if you want to buy now or continue with the free trial then just select continue to free trial.
  5. If you don't already have Adobe Acrobat Pro DC installed then it will upgrade itself to the fancier version, you don't have anything to do.
  6. Once Adobe Acrobat Pro DC is launched then make sure you sign into your account using the sign in button on the top-right.
  7. Now click the 'File' menu again and select 'Password Protect' or 'Protect Using Password'. Alternatively you can click on 'Edit' --> 'Tools' --> 'Protect' --> 'Protect using Password'.
  8. Select if you want to password for viewing or editing the PDF. Type and re-type your password. The password strength is indicated next to your password.  Once you're done click 'Apply'. You should see a confirmation message that the file was successfully protected using a password.
