Word to PDF Known limits

Convert a Word document to PDF entirely in the browser.

Worth knowing before you startDOCX is parsed via mammoth.js, then the HTML output is walked by DOMParser to produce a block-structured PDF with real selectable text using pdf-lib. Simple documents — single-column prose, headings, basic bullet lists, and inline images — convert faithfully. Complex tables, tracked changes, comments, headers and footers, footnotes, text boxes, and embedded fonts will drift or be omitted. For full layout fidelity, convert with Microsoft Word or LibreOffice on your own machine.

About this tool

Browser-based Word-to-PDF conversion is a convenience, not a replacement for desktop software. mammoth.js does an honest job on what it supports — clean prose documents convert reliably to readable PDFs. The limitation is the same as in any HTML-based rendering: the DOCX layout model and the HTML layout model are not equivalent, so the more the document depends on precise DOCX-specific features, the further the output drifts.

For anything where the visual layout of the output PDF matters — client-facing documents, formal reports, formatted templates — convert using the original application. For quickly turning a simple document into a shareable PDF without installing anything, this is fast and free.

Questions

Why do complex tables look wrong in the output?

mammoth.js converts DOCX to HTML, and tables with merged cells, complex borders, or conditional formatting do not have a clean HTML equivalent. The HTML-to-PDF step then applies default table styles. The result for simple tables is usually fine; the result for complex tables with spans and precise cell sizing is usually not.

What happens to tracked changes and comments?

Tracked changes are accepted silently — the output reflects the revised text. Comments are discarded. If your document has unaccepted revisions you want to review before converting, do that in Word or LibreOffice first.

When should I just convert on my own computer instead?

When the document has any layout complexity that matters: two-column text, headers and footers with page numbers, text boxes, mail merge fields, precise font choices, or complex tables. Word and LibreOffice both export PDF with full fidelity because they have the full rendering engine. This browser tool is a convenience for simple cases.
