PDF File Types

Don't think there's only one kind of gang in PDF files! PDF has three different types, namely Digitally Created PDFs, Scanned PDFs, and Searchable PDFs. Jaka will explain everything one by one.

1. Digitally Created PDFs

If you create a PDF file from scratch, the file is referred to as Digitally Created PDFs. Usually, this file contains only text and image elements.

PDF files like this are usually referred to as True PDFs.

The PDF file reader application that we have will detect the text and images separately.

2. Scanned PDFs

As the name implies, this PDF file is created when you scan using scanner. The documents you scan has the option to save as a PDF file.

Contrary to the first type, PDF reader applications cannot distinguish between text elements and image elements in this file.

Therefore, we will not be able to select the text in this PDF.

Well, actually you can, but you have to use a special application that Jaka will explain in point number 3 below.

3. Searchable PDFs

How to read text on Scanned PDFs file is to use the application Optical Character Recognition or often abbreviated as OCR.

How it works, this application will scan our PDF file to find the text in it.

After done doing scanning, the text will become a kind of new layer so that it can be detected by our PDF application.

Why Are PDF Files Locked?

Before proceeding to how to open a locked PDF, you must first know why some PDF files are locked by the owner of the file.

Broadly speaking, there is a main reason why PDF files are locked, namely to control who can access and modify the PDF document.

So, if there are important confidential documents, locking the PDF becomes an obligation so that no unauthorized people do it editing or even falsify documents.

By locking a PDF file, other people will not be able to print, copy or simply open it.

Examples of documents that must be locked are agreement documents, credit card bills, employment contracts, and other important documents.

1. Copyright Protection

Of course you know, how important is copyright? Well, one of the functions of locking a PDF file is to protect the copyright of the file maker so that the file is not copied or plagiarized by others.

2. Content Integrity

Still related to the previous point, PDF files need to be locked if we want to protect the contents of the file so that it won't be changed.

It could be that important information contained in our PDF files is changed arbitrarily by other people, so that the integrity of the content is reduced.

3. Digital Signature

With the PDF, we can do digital signatures. Well, it's dangerous for the gang, if our signatures are misused for bad deeds. That's why the PDF file is often locked.

4. Restricting Access

As Jaka mentioned above, one of the reasons why we need to lock PDF files is to limit who can access our files.
