Word to PDF: Why Formatting Breaks and How to Fix It
By the Advanced PDF Tools team | Last updated: June 2026 | 6-minute read
You spend an hour formatting a Word document. The headings look right, the table alignment is perfect, the fonts are exactly what you wanted. Then you convert it to PDF and something shifts. A paragraph breaks onto a new page it shouldn’t. Fonts change. An image that was anchored between two paragraphs drifts to the bottom of the page.
This happens because Word and PDF use fundamentally different layout engines. Word is designed for editing — it reflows content based on your screen, printer settings, and software version. PDF freezes everything into a fixed page. When the conversion happens, anything that wasn’t pinned precisely enough in Word can shift in the transition.
Here’s what actually causes the common problems, and how to prevent them.
Problem 1: Fonts Look Different in the PDF
This is the most common complaint. You use a custom or commercial font in Word, and the PDF displays a substituted font instead — usually Arial or Times New Roman standing in for something more distinctive.
Why it happens: Not all fonts are licensed for embedding in PDFs. When the converter can’t embed the font, it substitutes the closest available alternative. This also happens if the font isn’t installed on the machine doing the conversion.
Fix: In Word, go to File > Options > Save and check “Embed fonts in the file.” Then use File > Save As > PDF (not Print to PDF — see below). Embedding tells the exporter to include the font data in the output so it doesn’t need to be installed on the viewer’s machine.
If the font is unlicensed for embedding, the only real fix is to switch to a font that permits it. Common safe options: Calibri, Arial, Times New Roman, Georgia, Verdana, Open Sans.
Problem 2: Images Move or Jump to Wrong Pages
Images in Word are notoriously difficult to pin down. A photo that looks perfectly placed in editing view can land at the top or bottom of a completely different page in the PDF.
Why it happens: Word has two image anchoring modes. “In line with text” treats the image like a character — it stays where it is relative to the surrounding text. “Float” (the default when you drag an image into a document) anchors the image to a paragraph, which means if that paragraph moves, so does the image.
Fix: Select each image, right-click, choose Wrap Text > In Line with Text. This locks images in position relative to the text flow rather than floating. It’s less flexible for layout but much more predictable when exporting.
Alternatively: once you’ve exported to PDF, use our Word to PDF converter to handle the conversion — it often handles image positioning more reliably than the built-in Word export on older versions.
Problem 3: “Print to PDF” vs. “Save As PDF”
This is where a lot of formatting problems originate, and most guides don’t mention it.
When you use File > Print > Save as PDF (or the Microsoft Print to PDF printer), Windows renders the document as if it’s going to a physical printer, then captures that as a PDF. This process discards clickable hyperlinks, turns them into plain text, and can shift margins based on your default printer settings.
When you use File > Save As > PDF (or File > Export > Create PDF/XPS on newer Word versions), Word uses its own PDF export engine, which preserves hyperlinks, bookmarks, table of contents links, and handles fonts more faithfully.
Always use Save As / Export, not Print to PDF, unless you specifically don’t need working links in the output.
Problem 4: Table Formatting Breaks
Tables with merged cells, custom border colors, or cell padding often look fine in Word but render incorrectly in the PDF — cells merge unexpectedly, borders disappear, or text overflows.
Why it happens: Complex table formatting in Word uses a mix of character styles, paragraph styles, and table styles. Some converters don’t interpret all three consistently.
Fix: Before exporting, simplify the table wherever possible. Remove custom cell padding, use standard border styles (solid lines rather than dashed or dotted), and make sure no text in a cell is using manual line breaks to fake vertical centering. For important tables, check the PDF output at 100% zoom before sending.
Problem 5: Page Numbering Is Off
Sometimes the PDF starts page numbers from 1 when your Word document starts from a different number, or section-specific numbering doesn’t carry over.
Fix: In Word, go to Insert > Header & Footer > Page Number > Format Page Numbers and verify the “Start at” value before exporting. Also check that section breaks are set to “Continuous” vs. “Next Page” as intended — unexpected section breaks cause numbering resets.
The Cleanest Approach for Professional Documents
If you’re preparing something important — a contract, a client proposal, a resume — follow this sequence:
- Use Heading styles (not manual bold/size changes) for all headings.
- Set all images to “In Line with Text” anchoring.
- Use only fonts that support embedding (Calibri, Arial, Georgia, or similar).
- Export using File > Save As > PDF, not Print to PDF.
- Check the PDF at 100% zoom on a different screen or device before sending.
Five minutes of checking prevents an embarrassing resubmission.
