Removing
Security from PDFs: Individually and in Batch
Acrobat files may be secured using passwords, digital certificates or using rights management (provided by Adobe’s LiveCycle Rights Management server).
PDF documents circulated between sponsors, partners and clinical
staff are often secured to prevent changes and leakage of information.
PDFs which are secured cannot be changed. That means it is not
possible to add links, bookmarks or combine pages from these files as part of
your regular document operations. That certainly can pose a problem for regulatory
professionals who need full access to these documents to prepare submissions.
Because life science firms frequently secure PDFs, it was not too
surprising when I received a message last week from a large bio-pharma company
which posed this question:
Is there a way to batch process the removal of a password from
multiple PDFs?
Thee same password is used on multiple files . .
.
If you know
the password for a PDF, you can remove security from the document and make it
available for editing. Just click theSecure button, then choose Remove
Security:
You’ll be asked to enter your password, click OK, then save the
document.
While not difficult, that process is cumbersome when you have many
documents— perhaps hundreds— which need processing.
Fortunately, if you have Acrobat Pro, you can remove security from
documents in batch!
In this article, I’ll
discuss how to:

Checking Security on a PDF
When you open a PDF that has a password, you’ll see some immediate
indications that the file is secure.
Viewing and changing settings are just a click away.
A) The Title Bar of the document will display SECURED
B) The Navigation Panel will include a lock ICON
Unless you’ve changed the default user interface, you’ll also see
(C) a Security button. The Security Button offers quick, one-click access to
(D) view your security settings. If you choose Show Security Properties, you
can see what rights have been assigned to the document:
The Two Passwords of PDF
When you password protect a PDF, you can set a password which . .

§ Is required
to open a document (the OPEN password)
§ Limits use
of printing, copying or commenting (the USAGE RESTRICTION password)
Open passwords and Usage Restriction passwords may be used
individually or both may be present.
When removing security in Batch, you have to know which password
to use:

Creating a
Batch Sequence to Remove Security from Multiple PDF Documents
Follow these steps to remove security from multiple PDF documents
using Acrobat Pro.
First, you’ll need to change a preference so that Acrobat will
allow you to enter a password when you run a batch sequence.
1.
Choose Edit> Preferences (Windows) or Acrobat>Preferences
(Mac)
2.
Click the Batch Processing category at the left.
3.
Set the Security Method to Password
4.
Click OK
Tip:You may
wish to enable the check box "Save warnings and errors in log
file". If Acrobat cannot process a file, you’ll have a handy report you
can use.

1.
Choose Advanced> Document Processing> Batch Processing
2.
Click the New Sequence button and name your sequence (e.g.
Remove Security)
3.
Click the Select Commands Button
4.
The Edit Sequence window appears. Make the following changes:
A) Choose Security from the list at the left

the sequence, Acrobat will prompt you to locate the files and then process
them in place. Acrobat can, optionally, process specific folders and output
to specific folders, rename files and more.

Some Final
Thoughts
It is very important to take note of the table I
placed above.
If you are trying to unlock a document which has both an open
password and a usage restriction, you must enter the usage restriction
password. Acrobat will appear to process the file, but the document will remain
locked. Oddly, Acrobat did not log this as an error.
