EA-PDF: archiving email using PDF

February 2025 by PDF Association staff

Email is one of the most ubiquitous forms of communication in personal and professional contexts. Organizations worldwide rely on email at almost every level of daily operations, but they lack options for effectively preserving and accessing email over long periods of time.

Due to its widespread use and importance as an asynchronous communication medium, many organizations need to preserve and provide access to email messages. Although the transmission of completed emails is necessarily standardized, the wide variety of open and proprietary email file formats and systems creates challenges for long-term preservation

EA-PDF defines a mechanism for offline preservation of email source data together with a reliable static rendition of the email data. Based on existing ISO 19005 standards for archival-quality PDF files (PDF/A-3 and PDF/A-4f), EA-PDF provides institutions, corporations, and individuals with many benefits. The specification may be downloaded from the PDF Association’s website at no charge.
