What is PDF/A? Discover PDF vs. PDF/A

Undoubtedly, PDF is a reliable source for creating and storing text documents. There's another format known as PDF/A likely to replace PDF in the near future. You may call it the successor of PDF as it's a part of it.

Still, there are WHAT-IF related to PDF/A, which we'll discuss in this article. In this article, we'll discuss everything about PDF A, its types, its differences from PDF, and its advantages of using it. So, let's start with the "What" part.

What is PDF/A?

So, what exactly is PDF/A (Portable Document Format Archivable?) And why so being fussy about it when we already have PDF? PDF A is the futuristic version of creating PDF content or documents. The purpose of PDF A is almost the same as it is supposed to be in Adobe's Portable Document Format. But it sets strict standards for those who use PDFs.

In other words, PDF/A is nothing but another modified version of PDF with more features and functionalities. But that doesn't mean it is superior to PDF format. Still, you can expect exceptions from it. Well, there's another story of advantages and disadvantages; we'll discuss that later in this article. But first, let's get back to our topic.

PDF/A is a new archiving document format that promises to view the same document format for an extended period. PDF/A has characteristics that differentiate it from other types of files. Below are some attributes of PDF/A that shares different values:

  • Self-Contained: In self-contained attributes, it will display the text, images, fonts, colors, graphs, etc. - all this necessary information in your original document state. However, please remember that external references are not allowed in this file type.
  • Self-Documented: In self-documented PDF format, you can add metadata to your document. Metadata helps to understand the concern of the document.
  • Independent-Version: The independent version will make sure to use software chunks available on every standard device (RGB and specific CMYK colors side views), permitting the document to print or display on whatever device you use.

Types of PDF/A

Like the different attributes, PDF/A comes in different types. Each type has its own features created by other standards and congruity levels. Each standard determines the number of features available and image compression technologies that helps in archiving the content of a file.

There are three levels of congruity or conformance levels: Level b, known as the Basic level; Level a, known as the Accessible Level; and Level u, known as the Unicode Level.

Below are the three types of PDF/A

1. PDF/A-1b

PDF/A-1b is a level B conformance that gives you the assurance to read and view on the computer screen. But it won't ensure the quality of the text, whether it's legible or not.

2. PDF/A-2b

PDF/A-2b is another Level B subset ISO PDF identification that is used to create archival documents version with the ability to render precisely the same as they were before.

3. PDF/A-2u

PDF/A-2u is slightly different from the previous ones. Its conformance level is different as "u" stands for Unicode, which gives you a reliable way to search and copy the Unicode text from digitally created PDF documents and others that were scanned with successive OCR (Optical Character Recognition.)

All the above ISO standards or conformance levels are basically used for the everlasting preservation of PDFs.

Difference Between PDF and PDF/A

pdf vs pdf a

Well, you already know that PDF/A is a subset of PDF and is used to preserve digitally created documents for a long time. But when it comes to comparison with PDF, there are many visible differences between these two.

The first significant and clear difference between PDF and PDF/A is the limitations of a particular type of content. You can't submerge audio, video, and executable files. PDF viewer won't let you open a PDF/A file that contains this type of content. Plus, no one's sure to add another software or tool that allows you to access these types of files in PDF A format.

The other significant difference between PDF and PDF/A is that the second one is meant for preserving documents that can be restored when needed. On the other hand, a standard PDF can't preserve the documents.

Another thing that you can't do in PDF/A file format is encryption. Yes, you can't set any encryption of files and documents in this format. On the other hand, PDF allows different types of encryptions and restrictions. In PDF file format, you can increase the security of your PDF document by setting the user and owner passwords. Other protection includes setting restrictions on printing and copying content from your PDF.

Advantages of PDF/A

Doesn't seem to be a fan of PDF/A after covering the differences part. Well, don't disappoint, as PDF/A also has some advantages to play with.

PDF/A provides many advantages in areas of various applications;

  • Long-Term Preservation: As you already know that the primary purpose of PDF/A is to archive digital information for an extended period of time. This can include archives, libraries, banks, insurance companies, etc.
  • Binding Documents: You can also legally bind documents with the help of PDF/A format. The ISO standards already allowed electronic signatures and other facilities in this format. This means you can digitally sign your documents with this technology.
  • Worldwide Integration: In this PDF format, you can store your content in any foreign language that supports any kind of writing system around the globe. PDF/A ensures that the stored information is correctly viewed and displayed on any device in the world.
  • Independent Platform: PDF/A is not bound to any channel. Perhaps, documents stuck with this format can be accessed from various channels.
  • Text Searching: You can find any particular text or information within the data set. You can also do this in scanned documents even though one conformance level supports this functionality.
  • Reuse Content Easily: Level A makes it easier to reuse the content. These files can also be helpful while converting to Word, HTML, e-Books, and other formats.
  • Collaborate with Other ISO Standards: PDF/A provides a variety of ISO standards. Each standard can collaborate with one another.
