Convert Word to PDF

How to Convert Word to PDF

1

Add your Word files

Click “Select files” or drag and drop one or more .docx or .doc files. Batch conversion is supported.

2

Wait for local conversion

LibreOffice loads in your browser on first use (one-time ~30MB download, then cached). Subsequent conversions start instantly.

3

Download your PDFs

Each file converts independently. Downloads start automatically as each one finishes. Originals stay untouched.

Every step runs in your browser. No server uploads, no waiting.

Why use this tool

DukPdf’s Word to PDF tool converts DOCX and DOC files to PDF while preserving formatting, fonts, and images. The conversion runs entirely in your browser using LibreOffice compiled to WebAssembly — the same engine behind desktop office suites. Your document is read, converted, and saved without ever leaving your device. Need to convert a spreadsheet instead? Use Excel to PDF. For presentations, use PowerPoint to PDF. For a step-by-step guide, see our Word to PDF guide.

Word to PDF — questions

Will my formatting be preserved?

Yes. DukPdf uses LibreOffice for conversion — the same engine that powers desktop office suites. Fonts, headings, tables, images, and page breaks are preserved faithfully.

What about custom fonts?

Fonts embedded in the DOCX are preserved. If the document uses a system font not available in your browser, LibreOffice substitutes a metrically similar font. For exact font fidelity, embed fonts in the original DOCX before converting.

Are images preserved?

Yes. All embedded images — photos, charts, logos, shapes — are extracted and placed in the PDF at their original resolution and position.

Does it support .doc (older Word format)?

Yes. Both .docx (Word 2007+) and legacy .doc (Word 97–2003) are supported. LibreOffice handles both formats natively.

Is my document uploaded during conversion?

No. The entire conversion runs in your browser using WebAssembly. Open DevTools → Network tab while converting — zero upload requests carrying your document.

Why is the first conversion slow?

LibreOffice is a ~30MB WebAssembly payload. It downloads once on first use and is cached by your browser. All subsequent conversions start instantly.
