What do we know about PDF file formats and what benefits do they offer?
With the constant transition to the digital age, more and more people today rely on electronic documents. When discussing document file formats, PDF tops the list. In 1993, Adobe released the first PDF file format. Since then, many other variations of this well-known format have appeared, each with its own application. You are about to learn about them in this article.

There are a total of five PDF standards defined by the ISO organization. There are also PDF standards from other organizations, but we will not cover them in this article.
What is ISO?
ISO is the International Organization for Standardization, or the company that issues certificates for goods that meet its standards in various fields, including the Portable Document Format (PDF). ISO also sets standards through a complex certification process to ensure quality, reliability and versatility. In other words, the PDF standard for your document depends on how you intend to store, share and use it.
5 Different PDF File Formats
1. PDF/A is a subset of PDF designed for archiving information.
In order to keep the information in the file and ensure that the content looks good even after very long periods of storage, PDF/A sets stricter standards than those used in PDF.
Therefore, the main driving force behind the development of PDFA/A was to meet the needs of long-term archiving.
PDF/A viewers, such as Adobe Acrobat Reader, ensure that you can open files saved in this format even in the future.
2. PDF/E – PDF/E has been in use since 2008. PDF/E satisfies the different demands of both interactive and passive readers. Architects, engineers, construction professionals, and product development teams most often use this standard because it helps rotate and stack 3D objects on the screen. In addition, the inclusion of 3D engineering model data is a strength of PDF/E because many 3D data are somehow related to design workflows.
3. The PDF/X standard was developed at the request of the graphics and printing industries to facilitate document sharing. It is a standard that aims to avoid the problems that can occur when exchanging documents needed for seamless graphic production, i.e., professional printing.
4. PDF/VT adds support for color profiles, layers, and transparencies. VT is short for “variable and transactional”. So you can use this format to print everything from credit card bills and bank statements to postcards and personalized catalogs, from college application materials to Christmas greetings and photo albums. And also from labels to tickets and from checks to ID cards.
5. PDF/UA: The UA standard (short for Universal Access) helps people with disabilities access documents. When you open PDF/UA files with the appropriate software, you can open and read them with screen readers, screen magnifiers, joysticks, and other technologies to help visually impaired people access the content.
PDF file formats from ISO – Comparison
|Format type||Purpose of development||Users||Advantages|
|PDF/A||For long-term file storage.||Clerks,|
|Provides accurate reproduction of documents and ensures that archive files can be opened even after a long period of time.|
|PDF/E||To address key issues in the areas of large format drawings and multimedia.||Civil engineers,|
|Supports design and manufacturing specifications and also supports interactive multimedia, animation and stack 3D objects on the screen.|
|PDF/X||To ensure that documents are ready to print by correctly applying fonts, images or color profiles.||Print professionals,|
|Guarantees that the file will work when sent for professional printing (embedded fonts, no RGB colors, etc.).|
|PDF/VT||For variable data printing (VDP). From desktop printing to digital production machines.||Marketing campaigns,|
|Maintains color profiles, layers, and transparency in documents and can customize data, making it useful for printing bank statements, invoices, and personalized marketing material.|
|PDF/UA||To improve and ease readability for the visually impaired.||People with disabilities||This standard is compatible with assistive technologies that help users read and navigate.|
By defining the structure of a document using tags, assistive technology can determine the structure and reproduce the content accordingly.

In general, each PDF format has its own advantages, including the ability to embed multimedia content, security features, and cross-platform compatibility. In addition, they can be viewed on a variety of devices, making them ideal for sharing and distribution. If you are looking for a way to make your documents more accessible, convenient, and universally compatible, consider PDFs and their varieties.
