Once again, welcome to our blog! Today, we’ll be taking you guys on a journey on how to lock a PDF file. This guide will answer all your questions related to the topic without complicating things too much.
So, let’s first start with the basics.
Portable Document Format or PDF is a versatile file extension created by Adobe back in 1992. Thanks to its independence of software, operating system, or hardware, this format gives users a reliable way to share and view their documents.
PDF is an open standard, meaning it can be viewed and shared on any system regardless of its software/OS/hardware. To put it simply, a PDF file would look the same on any supportable system.
The International Organization of Standardization (ISO) maintains the PDF format. Here are some of the things you can insert in a PDF doc:
Businesses, institutes, schools, and, you name it, every industry uses PDF as their primary file format to view and share any document.
Why Lock a PDF File?
But hey, why would you want to lock PDF in the first place? Well, the gist of the deed is to block the access of any user that isn’t authorized to view or share the PDF. Here are some scenarios that’ll help you understand the tool’s use more easily:
Imagine you work in a financial company. Now, you want to pass on some critical information in the form of a PDF doc to specific bodies under and over you. It wouldn’t be wise just to send the document without any protection. Why? Simply because if it accidentally ends up in the hands of unauthorized parties, things can get havoc for you and your company. That’s where a PDF password protection tool would come into play.
For instance, you are a teacher in a university, and you are given the task to fine-tune the copies of upcoming examination papers. Once you are all done revising and setting up things, it’s time for you to send the docs to a couple of members. Without password protecting the PDFs, it would be quite a dangerous play as if someone unauthorized gets hold of them; you are in a complete mess.
So, there you have it. If you pass on a PDF document that’s only meant to be viewed by a couple of eyes, you should lock it.
