Is layout preserved 1:1?

We use mammoth.js to convert .docx to clean HTML, then render to PDF. Text styles and basic layout carry over; complex layouts (columns, headers/footers, embedded charts) may differ — perfect-fidelity Office→PDF requires LibreOffice.

Are my files uploaded?

No. Conversion happens locally with mammoth + jsPDF. Your files never leave your device.

Understanding word to pdf

A .docx file is a zip archive of XML. This converter reads that XML with mammoth, maps it to semantic HTML — headings, lists, tables, bold and italic — and then renders that HTML to PDF pages.

It deliberately extracts structure rather than trying to reproduce Word's exact pagination. Word's layout engine depends on installed fonts, printer metrics and dozens of undocumented behaviours that no browser can replicate exactly.

For text-heavy documents — letters, reports, CVs, essays — the result is clean and faithful. For documents built around precise placement, expect drift.

When you would use it

—Sending a CV as a PDF so formatting cannot shift on the recipient's machine.
—Publishing a policy document written in Word.
—Converting a contract draft for signature.
—Making a Word document readable on a device without Office.

Practical tips

Use Word's built-in heading styles rather than manual bold text; styled headings survive conversion, hand-formatted ones do not.
Legacy .doc files are not supported — save as .docx first.
Check page breaks in the output; the converter repaginates from scratch.

Troubleshooting

My layout looks different: Structure is preserved, absolute layout is not. Documents relying on text boxes and columns will reflow.
Images are missing: Embedded images are extracted where possible; floating and anchored images may be dropped.
