The PDF format was created by Adobe in 1993 to solve the problem of document appearance changing across different operating systems and printers.
Meanwhile, the DOCX format wasn't introduced until 2007 with Microsoft Office's major overhaul. Unlike its predecessor DOC, DOCX is actually a compressed ZIP archive containing XML files and media.
This XML-based structure makes DOCX more resilient to corruption than the binary DOC format.
Interestingly, while PDF was originally proprietary, Adobe released it as an open standard in 2008, helping it become the ISO 32000 standard.
Today, PDF/A variants are specifically designed for long-term archiving, with embedded fonts and color profiles to ensure documents look identical decades later.
Converting DOCX to PDF involves complex rendering processes that transform XML-structured content into a fixed-layout document format.
The conversion engine must interpret the OOXML (Office Open XML) schema that defines DOCX files, processing everything from paragraph styles to floating images.
Modern converters use intermediate representation trees to handle this transformation, preserving document flow while adapting to PDF's different pagination model.
Font substitution presents a particular challenge—when a document uses fonts unavailable on the conversion server, sophisticated algorithms must select visually similar alternatives or embed the original fonts.
Advanced converters also implement special handling for dynamic DOCX features like fields and macros, either by executing them before conversion or representing their final state in the PDF output.
