PDF/A (archival format)

PDF/A is a specialized version of the PDF format designed for long-term digital preservation. It ensures that a document remains unchanged and fully viewable over time, regardless of software updates or hardware changes. PDF/A embeds all necessary information, such as fonts and colors, to prevent loss of formatting or appearance. It’s commonly used for legal, governmental, and archival purposes to maintain the integrity and accessibility of important documents for years or decades.
