Twenty Years of Trust: Celebrating the 20th Anniversary of PDF/A-1

This month the PDF industry is celebrating the 20th anniversary of PDF/A-1 (ISO 19005-1:2005), the publication of which revolutionized digital preservation.
Before this standard, archiving suffered from dependency issues. PDF/A-1, based on a constrained subset of PDF 1.4, mandated self-contained, device-independent documents. These rules ensure that a PDF/A document’s appearance can be reliably maintained over centuries, regardless of viewing software.
Rapidly adopted globally, the principles established in PDF/A-1 persist in later standards like PDF/A-4, which is based on PDF 2.0, the latest ISO standard for PDF.
Happy 20th, PDF/A! We (ok, not us personally) fully expect to be celebrating your 200th anniversary in November 2225!
