How to Convert Word to PDF Without Losing Formatting

Why formatting breaks in conversion

A Word document looks the way it does because of three things working together: the file structure, the fonts available on your system, and the rendering engine used to display it. When you convert to PDF, all three need to translate correctly.

Most formatting losses come from one of these issues:

1. Fonts on your computer are not embedded in the PDF, so they substitute on the reader's device
2. Page margins or paper size were set differently in Word than in the PDF settings
3. Complex elements (text boxes, SmartArt, Word's specific features) do not have direct PDF equivalents

The good news: most issues are preventable if you check the right settings before converting.

The cleanest conversion path

If you have Microsoft Word installed, the most reliable conversion is to export directly from Word:

1. Open your document in Word
2. Click File, then Save As (or Export, depending on version)
3. Choose PDF as the format
4. Click Options before saving
5. Make sure "ISO 19005-1 compliant (PDF/A)" is unchecked unless you specifically need archival format
6. Check "Embed fonts" if available
7. Save

This bundles everything Word needs into the PDF, including fonts, so the file looks the same on any device.

When you do not have Word

If you cannot use Word, use the Word to PDF tool. Drop your .docx file in, and the tool converts it in your browser without uploading.

The tool handles standard formatting well: headings, paragraphs, lists, tables, basic images, and common fonts. For documents with simple to moderate formatting, the output is essentially identical to the source.

For complex layouts with text boxes, embedded charts, or unusual fonts, the result may need a quick review and adjustment.

Avoiding font substitution

Font substitution is the most common cause of subtle formatting changes. It happens when a font in your Word document is not available on the reader's system and the PDF substitutes a different font.

To prevent this:

• Use standard, widely available fonts (Calibri, Arial, Times New Roman, Helvetica, Georgia)
• Avoid free fonts from random sites unless you are sure they embed correctly
• If you must use a non standard font, embed it in the PDF during export (Word, "Save As", "Tools", "Save Options", "Embed fonts in the file")

A common gotcha: emoji and special symbols often substitute even with font embedding. Test these specifically in the output.

Handling tables and complex layouts

Tables convert well when they fit within a single page. Tables that span multiple pages can sometimes break awkwardly in PDF, especially if rows are tall.

Tips:

• Set "Repeat header rows" in Word so each new page shows the table header
• Avoid merged cells where possible (they cause more conversion glitches than they are worth)
• Test print preview in Word before converting; if it looks good there, it usually converts cleanly

For Word documents with text boxes or floating images, the PDF positioning is usually accurate but sometimes shifts by a few pixels. Review carefully if exact placement matters.

Multi page documents and TOCs

Tables of contents in Word use field codes that need to be updated before converting:

• Click anywhere in the TOC
• Press F9 to update
• Choose "Update entire table" if prompted

If you skip this, your TOC may show old page numbers or missing entries. The fix takes two seconds but is easy to forget.

Common problems and quick fixes

Problem: text appears in a different font than my Word document. Fix: the font was not embedded. Re-export with font embedding enabled.

Problem: page margins look different in the PDF. Fix: check that the paper size in Word matches the PDF output (both A4 or both Letter).

Problem: bullet points appear as little squares or boxes. Fix: the bullet character font was substituted. Use standard bullets or change to a font with broader symbol support.

Problem: table borders look different or missing. Fix: in Word, explicitly set table borders (some default borders are theme dependent and convert inconsistently).

Problem: hyperlinks do not work in the PDF. Fix: re-export and make sure "Create bookmarks" and "Include document properties" are enabled in the PDF options.

After converting

Once you have a clean PDF, you can:

• Merge it with other PDFs using Merge PDF
• Clean the author metadata with PDF Metadata
• Add a password with Protect PDF before sharing

For documents you will send to many people, do one careful conversion, review thoroughly, and reuse that PDF rather than re-converting from Word each time.
