What Is PDF/A?
PDF/A is an ISO-standardized version of the PDF. It is specialized for use in the archiving and long-term preservation of electronic documents. So, the PDF/A file format eliminates features in PDF unsuitable for long-term archiving like font linking and encryption.
Because of the PDF/A file’s long-term preservation feature, it often is used by government, industry, and academic areas worldwide, including legal systems, libraries, newspapers, and regulated industries.
PDF/A comes in many different possible variants, distinguished by PDF/A standards (PDF/A-1, PDF/A-2, PDF/A-3) and conformance levels (a, b, u) they use.
PDF/A Standards
PDF/A-1 is based on PDF 1.4, while PDF/A-2 and PDF/A-3 are based on PDF 1.7.
PDF/A-2 adds some new features, namely transparency, JPEG 2000, layers, and attachments (only other PDF/A files), over PDF/A-1.
PDF/A-3 has one feature that differs from PDF/A-2 in that it allows any type of file to be added as an attachment.
PDF/A Conformance Levels
Level b conformance is the easiest level to achieve, as it requires only that documents conform with guidelines for reliable viewing.
Level aadds to the information requirements and aims to preserve the logical structure, semantic content, and natural reading order of the document.
Level u has the same requirements on Unicode as level a but degrades some of the requirements of level a, like logical structure and aspects of natural reading order.
