Converting Word to PDF should preserve your formatting exactly — and usually does, if you use the right export method. The cases where formatting breaks after conversion almost always trace back to one specific cause: how the PDF was generated. Understanding the difference between export methods explains most formatting problems and points directly to the fix.
The Two Export Methods — and Why One Breaks Formatting
There are two common ways to create a PDF from Word, and they produce very different results:
- File > Save As > PDF (or Export to PDF): Word's native PDF export. This uses Word's own PDF engine, which understands the document's internal structure — styles, fonts, layout, hyperlinks, bookmarks. It produces the most faithful PDF reproduction of your document.
- File > Print > Save as PDF (Print to PDF): routes the document through the print system. The print renderer interprets the document visually, like a printer would. It loses structural information — hyperlinks become plain text, bookmarks disappear, accessibility tags are stripped. Layout is usually preserved but structural features are not.
For the best formatting preservation, always use Word to PDF via File > Save As > PDF, not via the print dialog. This is the single most important thing you can do to avoid formatting problems.
Fonts: The Most Common Formatting Problem
If your PDF looks different from the Word document — different typeface, different letter spacing, text wrapping differently — fonts are almost certainly the cause. When a PDF doesn't embed fonts, viewers substitute whatever is available on their device. The substitution changes everything that depends on character width.
Word's native PDF export embeds fonts by default. Verify this by going to File > Save As > PDF > Options and confirming that "ISO 19005-1 compliant" or font embedding options are set correctly. If you're using a third-party PDF printer driver rather than Word's native export, check its settings for font embedding — not all drivers enable it by default.
Tables and Multi-Column Layouts
Tables and multi-column layouts in Word are complex structures. Most of the time they convert cleanly to PDF. When they don't, the issue is usually in the Word document itself rather than the conversion — a table that's slightly too wide for the page margins, or a column layout with inconsistent spacing.
Before exporting, check the print preview in Word (Ctrl+P). The print preview shows exactly what will appear in the PDF — if it looks wrong in preview, it'll look wrong in the PDF. Fix layout issues in Word first, then export. A PDF that looks wrong is almost always telling you that the Word document had a hidden layout problem.
Page Breaks and Unexpected Blank Pages
Extra blank pages in the PDF usually mean extra paragraph marks or page breaks at the end of the Word document. Turn on formatting marks in Word (Ctrl+Shift+8) and look for paragraph marks or page break symbols after the last line of content. Deleting these before export prevents blank pages from appearing in the PDF.
Unexpected page breaks in the middle of content are usually caused by "Page break before" paragraph formatting applied to headings or specific styles. In Word, right-click the heading, go to Paragraph > Line and Page Breaks, and check whether "Page break before" is checked when it shouldn't be.
Images Shifting Position in the PDF
Images that are "floating" in a Word document — set to wrap text around them, or placed with a fixed position on the page — sometimes shift slightly when exported to PDF. This happens because the float positioning is interpreted slightly differently by the PDF engine than by Word's layout engine.
The most reliable fix is to set images to "In line with text" rather than floating — this anchors them to the text flow, which converts predictably. For images that must stay in a specific position, check the PDF result carefully and adjust the image position in Word slightly if needed before re-exporting.
Converting Without Word Installed
If you don't have Word available, WukongPDF's Word to PDF converter at www.wukongpdf.com handles .docx files directly in the browser. Upload the Word document, download the PDF. For standard documents — reports, letters, proposals — the formatting is preserved well. For complex documents with custom styles, unusual fonts, or intricate layouts, Word's native export produces more reliable results when available.
