How to Convert DOCX to PDF for Free: Steps, Page Size, and What Survives the Trip
A job portal that only takes a PDF CV. A tutor who wants the essay as a PDF by midnight. A contract nobody should quietly edit. Each time you have a Word file and need a PDF of it. This guide shows how to turn DOCX to PDF and Word to PDF with no copy of Word to hand, which page size to pick, what comes through cleanly, and when Word’s own export is the better choice. To convert Word to PDF right now, use the tool above.
1. Word to PDF: What It Does and When to Use It
A .docx file is the format Word has saved in by default for years, defined in the ECMA-376 Office Open XML standard. It is built to be edited, and how it looks depends on the fonts and program of whoever opens it. A PDF, set out in ISO 32000-2, is built to be read: pages are fixed and it opens the same way everywhere. That is why portals, universities and legal teams ask for PDFs.
The tool reads one .docx file and writes a fresh PDF from it: your paragraphs, headings, lists, links and pictures, on the paper size you pick. Many people search doc to PDF when they mean any Word file, and for a .docx that is exactly what you get. An old-style .doc file from Word 97–2003 is a different format, and so are .odt, .rtf and .pages files; this tool reads only .docx. Re-save the file as .docx from the program that opened it, or try the file converter hub for other document formats.
It suits text-led documents: letters, essays, reports, policies, contracts and simply laid-out CVs. If yours relies on columns or a designed letterhead, read section 4 first.

3. Will My Document Convert Well? A Checklist
It depends on what is in the file. Here is what comes through.
Kept well:
- Headings and structure. Title and Heading 1 to 6 styles print in bold at sizes that step down from the title, so a DOCX to PDF keep headings and bullet points job works: bulleted and numbered lists keep their nesting, numbered 1., 2., 3. and bulleted with round markers.
- Text styling. Bold, italic, underline, font size and colour. Code fonts such as Consolas stay monospaced.
- Pictures. Word to PDF with images works for PNG, JPEG, GIF, WebP and BMP pictures placed in the text, shown at the size you gave them in Word.
- Layout basics. Left, centre and right alignment, left indents, spacing after paragraphs, manual page breaks and “page break before”.
- Links and edits. Hyperlink text shows blue and underlined. Tracked insertions are kept and tracked deletions left out. The document title and author carry over.
Simplified or left out: headers, footers, footnotes, comments, multi-column sections, text boxes and SmartArt. Tables come through as plain grids of text, without shading, merged cells or bold cells. Justified paragraphs are set left-aligned. Older EMF and WMF drawings, common in documents with Visio diagrams, are dropped.
Five minutes of prep that pays off. Before you convert, accept or reject any tracked changes so the PDF shows the wording you agreed. Move anything important out of a header, footer or text box and into the body, because those areas are not carried across. If a table matters, keep it simple: one header row, no merged cells, and short cell text. Replace any EMF or WMF diagram with a PNG or JPEG copy of it. Finally, give the file a clear title and author in Word’s document properties, since those become the PDF’s own title and author.
4. Why Fonts and Formatting Change in the PDF
If you are asking why do fonts change when converting Word to PDF, here is the plain answer for this tool. It does not copy Word’s pages; it lays the document out afresh using the standard PDF fonts, Helvetica for ordinary text and Courier for monospaced text. Your original typefaces are not embedded, so a CV set in a designer font will arrive in a clean sans-serif. Line breaks and page breaks can fall in different places, the usual cause of Word to PDF formatting changes.
Non-Latin text prints as question marks. The standard fonts cover Western European alphabets only. Chinese, Japanese, Arabic, Hebrew, Cyrillic and Greek characters, and emoji, appear as “?” in the PDF. For those documents, use Word’s own export described below.
When the exact look matters (a designed letterhead, a two-column newsletter, a document in Arabic), the faithful route is Word itself: open the file, choose File, then Save As or Export, and pick PDF. That keeps the original fonts, headers and footers. Use this tool when Word is not available, or when you want a tidy PDF of a text-led document that is never stored on our servers.
5. CVs, Assignments, Contracts and Chromebooks
- Convert resume DOCX to PDF, because many application portals ask for a PDF CV. Keep the CV to headings, bullet points and plain text, and check the preview; two-column templates are simplified.
- Convert assignment Word to PDF for submission: pick the paper size your institution uses, keep the default margins unless told otherwise, and add page numbers afterwards if required (section 6).
- Convert contract DOCX to PDF privately: files are never stored on our servers, nothing is retained, and nothing is used for training. Tracked deletions are dropped, so settle the redline in Word first.
- How to convert DOCX to PDF on Chromebook? Open this page in Chrome, choose the .docx from your Files app or Google Drive, and convert. The PDF saves to your Downloads folder.
- How to convert Word to PDF without Microsoft Office? You need no copy of Word and no Office subscription: add the .docx above and convert. The same goes for a library PC, a borrowed laptop, or when you convert Word to PDF on work computer without admin rights and Word is missing.
6. Converter Not Working? Fixes and Next Steps
When a Word to PDF converter not working is the problem, the message says why. Choose a .docx file first. means nothing was selected. Not a Word document (word/document.xml missing) means the file is not a real .docx: usually a renamed .doc, an .odt or a damaged download. Save it again as .docx and retry. “?” in place of letters means a script the standard fonts do not cover (section 4).
To convert Word to PDF and add page numbers, run the output through PDF page numbers, since Word’s own footers are not carried across. To merge Word documents into one PDF, convert each file in turn, then combine them with the PDF merger. Want a clickable outline built from your headings? Add it with PDF bookmarks.

Can I convert a .doc, .odt or Google Docs file?
No, only .docx files are read. Re-save the document as .docx, or download it from Google Docs as a Word document, then convert it here.
My Word attachment will not open. Can I get a PDF instead?
Yes. A search like "docx file won't open need PDF" usually means Word is not available to you, so convert the .docx here and open the PDF in any reader. If the tool says it is not a Word document, ask the sender to save it again as .docx.
Are images and tables kept?
PNG, JPEG, GIF, WebP and BMP pictures are kept at their Word size. Tables become plain text grids without shading or merged cells. EMF and WMF drawings are left out.
Can I convert several Word files at once?
The tool converts one file per run. Convert each document in turn, then combine the PDFs into a single file with the PDF merger.
Will headers, footers and page numbers carry over?
No, headers, footers and footnotes are not included in the PDF. Add page numbers afterwards with the PDF page numbers tool on the finished PDF.
