Did you know?

What is PDF/A?

PDF/A is a PDF format that imposes certain restrictions on the essential parts of digital documents, including text, images, vector graphics, and related metadata, suitable for long-term storage. It is an ISO standard format and is now widely adopted in all industries. This PDF/A format guarantees that you can open your document, no matter what software you use, because essentially all the information needed to display the document and its elements in the same way is included in the file. In the digital age, it's important to have a reliable and secure format for storing and sharing electronic documents. PDF/A was created to meet this need, providing a standardized format for long-term storage and accessibility of digital documents. Whether you work in government, finance, law, or other industries, PDF/A is an important tool for preserving important digital documents for the future. There are many different types of PDF/A. Each of them has different PDF/A standards and conformance levels.

Types of PDF/A

PDF/A-1b

Ensures that text and other content on pages are uniformly readable and viewable by users on their computer screens. This Level B level provides minimal guarantees that the rendered visual appearance of the document will be preserved over the long term, but does not guarantee the quality of the text.

PDF/A-2b

It is based on PDF 1.7 (ISO 32000-1) and guarantees that your document will render exactly as it did when it was first saved. It offers several new features, such as JPEG 2000 image compression, support for transparency and layers, and electronic signatures.

PDF/A-3b

Like PDF/A-2, it is based on PDF 1.7 (ISO 32000-1). You can embed any document format in your PDF documents, such as Excel, Word, HTML, CAD or XML files.

Benefits of the PDF/A format

The primary purpose of PDF/A is long-term archiving of digital documents. Today, libraries, banks, insurance companies, and all industries convert key documents to PDF/A for use.
The PDF format is accessible on all platforms, and the PDF/A format has the same benefits. This means that you can perfectly read and use PDF/A documents whether your OS is Windows or Mac.
In a digital environment, it is more important than in an analog environment that documents remain authentic, that they are not modified after they are created, and that documents with original content modified are not shared. The PDF/A format cannot fully guarantee the authenticity of a document, but it is difficult to modify and provides an electronic signature to help determine authenticity.
Electronic documents can contain a lot of information as metadata, such as the author's name and the date of the file. Therefore, it is important to be able to save and add this metadata when converting the original electronic document to another file. PDF/A was specifically designed to fully support metadata.
The PDF format has been around since 1991, so the format isn't going away any time soon. Therefore, PDF/A will remain easy to read and use as long as PDF exists.
