About Word to PDF
Word documents reflow: the text wraps to whatever page or window it is shown in. A PDF freezes that layout into fixed pages, which is why contracts, CVs and invoices are sent as PDFs. The hard part of converting is deciding how the document should break across pages, how wide the margins are and which fonts the reader will have, because Word and a browser will never agree on every glyph width.
This converter reads the .docx package with mammoth, turns its structure into styled HTML and renders that to PDF pages. You get two routes: a direct download that renders the pages as images, and a print view that keeps real, selectable text if you choose Save as PDF in the print dialog. Both are useful, and the workspace tells you which trade-off you are taking.
What this tool does
Two output routes
Download a rendered PDF instantly, or open the print view and save as PDF when you need selectable, searchable text.
Structure preserved
Headings, paragraphs, bold and italic, numbered and bullet lists, tables and inline images are kept in their document order.
A4 or US Letter
Choose the paper size and a normal, narrow or wide margin before rendering, so the result fits local printing standards.
Parsed-content preview
Open the preview before converting to check that the document was read correctly and to see any converter warnings.
No upload
The .docx stays on your device. There is no account, no job queue and nothing to clean up afterwards.
Images included
Inline pictures are carried through as data inside the document and rendered with the surrounding text.
How to use Word to PDF
- 01
Add the Word file
Drop a .docx file onto the workspace or click Choose file. Legacy .doc files need to be re-saved as .docx in Word first.
- 02
Check the parsed preview
Expand Preview parsed content to confirm the headings and paragraphs were read correctly. Warnings are listed above it.
- 03
Choose the page setup
Select A4 or US Letter and pick the margin width that suits the document.
- 04
Convert or print
Click Convert to PDF for a downloadable file, or Open print view and choose Save as PDF in the browser dialog for selectable text.
- 05
Download the PDF
Save the file, then open it once to confirm the page breaks and table widths look right.
Supported formats and limits
- Input
- DOCX
- Output
- Processing
- Client-side, in your browser. Nothing is uploaded.
- Maximum size
- Up to 30 MB
- Requirements
- Chrome, Edge, Firefox or Safari · Pop-up permission for the print view
Limitations worth knowing
- Legacy .doc files are not supported; save the document as .docx first.
- Layout fidelity is limited. Text boxes, multi-column pages, headers and footers, footnotes and tracked changes are simplified or dropped.
- The direct download produces image-based pages, so its text is not selectable; use the print view for searchable text.
- Up to 30 MB per file. Image-heavy documents take several seconds, and very long documents (dozens of pages) can exhaust the browser canvas — use the print view for those.
Privacy and file handling
Your .docx file is opened, parsed and rendered entirely within your browser. It is never uploaded to FormatFlow or anyone else, and no copy of the document or its images is stored. The PDF is assembled in memory on your device and disappears when you close or reset the tool.
