Word to PDF

Word to PDF turns a .docx document into a PDF using your browser. It usually keeps headings, paragraphs, lists, pictures and basic tables, and the file never leaves your device. It is a visual rendering, not a Word export, so complex layouts may differ.

How to convert Word to PDF

1. Drop your .docx file onto the tool or click Choose file. Files can be up to 20 MB.
2. Wait while the browser reads the document and builds a preview. A short conversion-notes list appears if some Word features cannot be fully reproduced.
3. Choose A4 or Letter, an orientation, and a margin of 0, 10 mm or 20 mm.
4. Scroll through the preview. It shows the converted formatting; page size and margins are applied when the PDF is created.
5. Click Convert to PDF and wait for rendering and pagination to finish.
6. Download <name>.pdf. Your original .docx file is not changed.

DOCX versus DOC

.docx is the Office Open XML format used by Word 2007 and later: a ZIP package of XML files, styles and embedded images. .doc is the older binary format from Word 97 to 2003. This tool reads .docx only. A renamed .doc still cannot be opened.

To convert a legacy .doc, open it in Word, LibreOffice or Pages and save or export a copy as .docx. Save a .docm file as .docx to remove its macros, and remove any password before converting. Macros are never run, and macro code is not carried into the PDF.

How the conversion works

Mammoth reads the document's XML and converts it into semantic HTML. Headings become heading elements, lists become lists, tables become tables, and embedded pictures become data URIs inside the HTML, so they are not fetched separately.

The HTML is laid out in a hidden, sandboxed frame using a clean stylesheet for A4-width content, fonts, tables and images. This is the browser's layout engine, not Word's: it decides where lines wrap and how tall the content becomes.

The page is drawn at twice the normal screen scale, roughly 192 pixels per inch. The tall rendering is cut into page-sized JPEGs and placed into an A4 or Letter PDF with your margins. The PDF's page breaks come from that cutting, not from Word. Auto orientation uses portrait and switches to landscape when the content is wider than a portrait page.

What is usually preserved

Ordinary text documents come through best. The converter generally keeps:

• Headings that use Word's built-in Heading 1 to Heading 6 styles.
• Paragraphs and basic emphasis such as bold and italic text.
• Bulleted and numbered lists, including nested levels.
• Pictures embedded in the .docx.
• Simple tables, with rows, cells and uniform borders added by the stylesheet.

Text and pictures keep the order Mammoth reads from the document. Simple tables often look close to the original, though their exact column widths are not copied.

What may shift or disappear

This is a browser rendering of converted HTML, so it cannot reproduce everything Word can do:

• Columns. Multi-column sections are flattened, so side-by-side text can end up in a different reading order.
• Text boxes, shapes and drawings. These are often missing or flattened into the text. SmartArt, charts and equations may be incomplete.
• Pictures. Images use their natural size, capped to page width; wrapping is lost.
• Headers and footers. Running headers, footers and page numbers are usually lost, or become ordinary content rather than repeating.
• Fonts. Calibri, Carlito, Segoe UI or Arial are used when available; missing fonts can change line lengths and page count.
• Page and section breaks. Original breaks are ignored; pages are cut by height after rendering.
• Tables. Merged cells, shading, exact widths and large tables may be simplified or overflow.
• Comments, tracked changes and form fields. These are not preserved as editable or interactive content.

The original page size is also ignored. Choose Letter if the file used it. For exact typography, export from Word or LibreOffice.

Text selectability and accessibility

Every PDF page is a JPEG image. The text looks normal, but there is no text layer, so you cannot select, copy, search or highlight it. A screen reader has no words to read, and links or form fields are not interactive.

At about 192 pixels per inch, it is comfortable on screen and for ordinary printing; zooming shows JPEG softness around small text. For a searchable PDF, use Word's Save As or Export command, or run OCR separately. This converter does not perform OCR. Keep the .docx as your editable master.

When to use Word to PDF

Use this tool for everyday documents where words and structure matter more than pixel-perfect design: letters, reports, CVs, notes, policies, essays and simple proposals. It suits sharing, printing or submitting a fixed copy when you do not have Word installed.

It is less suitable for brochures, forms, contracts with careful typography, or documents that rely on columns, text boxes and repeating headers. For a spreadsheet, use Excel to PDF; for web pages, HTML to PDF; to go the other way, PDF to Word.

Very long documents use more memory because each page is held as an image. Documents over roughly 250 pages are refused; split them first.

Privacy

Mammoth, html2canvas and pdf-lib all run inside your browser. The document, its embedded pictures and the finished PDF are processed on your device and are never uploaded to Lembog or any third party. There is no account or stored copy after you close the page.

The page is downloaded from this website, but your Word file is not sent with it. Use a device you trust for confidential documents.

Word to PDF FAQ

Is this Word to PDF converter free?

Yes. There is no sign-up and no watermark. Files can be up to 20 MB, and documents over about 250 pages are refused.

Are my Word documents uploaded?

No. The .docx is read and rendered entirely in your browser. Nothing is sent to Lembog or another service, and no copy is stored after you leave the page.

Can I convert a legacy .doc file?

No. This tool only reads .docx. Open the .doc in Word, LibreOffice or Pages, save or export it as .docx, and convert that copy.

Why does the PDF look different from the document in Word?

Word and the browser lay out text differently, and the converter rebuilds the document from HTML rather than using Word's page engine. Fonts, columns, tables, text boxes, headers and page breaks can all change.

Is the text in the PDF selectable or searchable?

No. Each page is a JPEG image, so the words cannot be selected, copied, searched or read by a screen reader. For a searchable PDF, export directly from Word or LibreOffice.

Does it keep images and tables?

Pictures embedded in the .docx are usually included, and simple tables are rebuilt with borders. Floating images, complex tables, merged cells, charts and drawings may be missing or simplified.

Can I convert a password-protected or macro-enabled file?

Not directly. Remove the password and save an unprotected copy. For a .docm file, save a .docx copy, which also discards the macros. Macros are never run.

Why is the finished PDF large?

Every page is a JPEG image, so a text-heavy document can be larger than a normal Word export. Use Compress PDF for a smaller copy.
