What this actually does
This reads your .docx file's text structure — paragraphs, headings, bold/italic, lists, basic tables, and inline images — using Mammoth, an open-source library that deliberately converts structure rather than trying to pixel-match the original. It then opens your browser's native print dialog, where choosing "Save as PDF" produces a real PDF with selectable, searchable text (since it uses your browser's own PDF engine, not an approximation).
What's not preserved: exact fonts and font sizes, precise colors, exact page margins and layout, headers/footers, page numbers, and complex multi-column layouts. For straightforward text documents — letters, reports, articles, resumes without heavy custom design — this works well. For documents with precise visual design requirements, exporting directly from Word ("Save As" → PDF) will match the original far more closely.
