When you share a Word document as a PDF, fonts that are not installed on the recipient’s computer get replaced. This substitution can change page breaks, alter table widths, and break the layout you carefully designed. The root cause is that PDF viewers fall back to default system fonts when the original font is missing.
Word includes a font embedding feature that saves the actual font data inside the PDF file. This ensures the document looks exactly the same on any device regardless of which fonts are installed locally. However, the default settings do not embed all fonts, and some font licenses restrict embedding.
This article explains how to force Word to embed every font used in your document, how to check which fonts are already embedded, and what to do when a font refuses to embed. You will also learn how to verify the final PDF for correct font rendering.
Key Takeaways: Embed All Fonts in Word for PDF
- File > Options > Save > Embed fonts in the file: Turns on font embedding for the current document and all new documents.
- Embed only the characters used in the document (best for reducing file size): Uncheck this option to embed the full font set and prevent missing glyphs when the PDF is edited elsewhere.
- Do not embed common system fonts: Keep this unchecked to force embedding of fonts like Arial and Times New Roman, which may still look different on other operating systems.
How Word Handles Font Embedding and Why It Fails
Word embeds fonts by copying the font file data into the document file itself. When you later export to PDF, that embedded font data is carried over. The feature works with TrueType (.ttf), OpenType (.otf), and PostScript Type 1 fonts. It does not work with bitmap fonts or fonts that have a license restriction marked as “No embedding allowed.”
Font licenses fall into three categories. Installable embedding allows the font to be permanently embedded. Editable embedding allows embedding but only for viewing and printing, not for editing in the PDF. Preview and print embedding allows the font to be temporarily loaded for display and printing. No embedding means the font cannot be included at all. Word respects these license flags and will skip fonts that do not permit embedding.
What Happens When a Font Is Not Embedded
If a font is missing from the PDF, the PDF viewer substitutes a default font. On Windows, that is typically Microsoft Sans Serif. On macOS, it is Helvetica. The substitution changes character widths and line heights, which can cause text to overflow containers, shift images, or alter the pagination of a multi-page report. Embedding all fonts prevents these layout shifts entirely.
Steps to Embed All Fonts in Word for PDF Export
The following procedure works in Word for Microsoft 365, Word 2021, Word 2019, and Word 2016 on Windows. Mac users have a separate setting under Word > Preferences > Save.
- Open the Save options in Word
Click File in the top-left corner. Select Options at the bottom of the left pane. In the Word Options dialog, click Save in the left sidebar. - Enable font embedding for this document
Scroll down to the Preserve fidelity when sharing this document section. Check the box labeled Embed fonts in the file. This activates the two sub-options below it. - Configure the embedding sub-options
Uncheck Embed only the characters used in the document (best for reducing file size). When this is checked, Word embeds only the glyphs that appear in your text. If someone later edits the PDF and types a character you did not use, that character will be missing. Unchecking this forces the entire font to be embedded.
Uncheck Do not embed common system fonts. By default, Word skips fonts like Arial, Calibri, and Times New Roman because it assumes the recipient has them. On macOS or Linux, those fonts are not present or render differently. Unchecking this forces Word to embed them as well. - Apply the setting to all future documents (optional)
In the same dialog, locate the Global options section at the top. Check Embed fonts in the file there as well. This makes the setting the default for every new document you create. Click OK to close the dialog. - Save the document
Press Ctrl+S to save the current document. Word now stores the font data inside the .docx file. This increases the file size but guarantees portability. - Export to PDF
Click File > Export > Create PDF/XPS. In the Publish as PDF or XPS dialog, click Options. Under PDF options, ensure Document structure tags for accessibility is checked if you need screen-reader compatibility. Click OK, then click Publish. - Verify font embedding in the PDF
Open the PDF in Adobe Acrobat Reader. Press Ctrl+D to open Document Properties. Click the Fonts tab. You should see every font used in the document listed with the label (Embedded Subset) or (Embedded). If a font appears without that label, it was not embedded.
When a Font Cannot Be Embedded
Some fonts have license restrictions that prevent embedding. If Word cannot embed a font, it will still create the PDF, but that font will be substituted on the recipient’s machine. You have three options to handle this situation.
Replace the Restricted Font
Select all text that uses the restricted font. Change the font to a similar one that allows embedding. Common safe fonts include Calibri, Cambria, and Times New Roman. These are licensed for embedding and are widely available.
Use a Font That Allows Embedding
If you purchased a font from a vendor, check the license agreement. Many commercial fonts sold through Google Fonts, Adobe Fonts, or Fontspring allow embedding for PDF distribution. Download a version of the font that has installable embedding permissions.
Rasterize the Text as a Last Resort
If you must use a font that cannot be embedded and you cannot change it, convert the text to an image. Select the text, copy it, and paste it as a picture using Paste Special > Picture (PNG). The text becomes a static image and will appear correctly in the PDF. This removes the ability to search or copy the text.
Word Online vs Desktop: Font Embedding Behavior Differences
| Item | Word Desktop (Windows/Mac) | Word Online (Browser) |
|---|---|---|
| Font embedding setting available | Yes, in Save options | No, not available |
| Embedding during PDF export | Respects embedding flags from font file | Does not embed any fonts |
| PDF output font handling | Embedded fonts preserved | All fonts substituted with system fonts |
| File size of PDF | Larger due to font data | Smaller, no font data |
| Cross-platform appearance | Identical on any device | May shift layout on different OS |
Word Online cannot embed fonts because it runs in a browser sandbox and does not have access to the local font files. If you need reliable font embedding, always use the desktop version of Word to create the PDF.
You can now configure Word to embed all fonts, including system fonts, so your PDF looks identical on any operating system. After enabling the setting, always verify the PDF font list in Document Properties to confirm no font was skipped. For documents that use restricted fonts, replace them with embeddable alternatives before exporting. This approach eliminates layout surprises when sharing reports, proposals, or forms with clients and colleagues who use different platforms.
