- Preparing an existing PDF for professional printing where all fonts must be fully embedded, but some legacy fonts are missing.

Embed Fonts Using Acrobat Pro Preflight Utility
If you have Adobe Acrobat Pro DC, you can use the built-in Preflight tool to embed fonts that are missing, provided you have them installed on your computer.
This method requires you to first identify which fonts are missing and install them on your system before running the utility.
Go to File > Document Properties > Fonts to see a list of all fonts used in the PDF. Note which ones are missing or not marked as embedded.
Locate copies of the missing fonts (such as older legacy fonts) and install them directly onto your computer's operating system.
Open the Preflight panel located on the right side of your workspace, typically found under the PDF Standards group.
Navigate through the Preflight section and follow the available on-screen instructions to run the fix that embeds the required fonts into your PDF.
Manually Replace Missing Fonts
If you cannot find the original missing font or do not have access to a Preflight utility, replacing the font with an installed alternative is an effective workaround.
Easily Edit and Replace PDF Fonts with WPS Office
WPS Office provides a comprehensive PDF Editor that allows you to easily modify text and replace missing fonts. By editing your document in WPS Office, you can ensure your text uses available system fonts, making the file fully ready for professional printing.
- 1. Open PDF in WPS Office: Launch WPS Office and open the PDF file containing the unembedded fonts.
- 2. Enter Edit Mode: Click on the 'Edit PDF' tab in the top navigation ribbon to access text editing tools.
- 3. Replace the Font: Select the text with the missing font and choose a new system font from the text properties menu.
- 4. Save and Embed: Save the document. The PDF will update, and the newly selected font will be correctly embedded.
Frequently Asked Questions
Why do fonts need to be embedded in a PDF?
Embedding fonts ensures that the document looks exactly the same on any device and meets professional printing standards. If a font is not embedded, the printer or viewer may replace it with a default system font, potentially ruining the layout and text spacing.
Can I embed missing fonts using free online PDF tools?
Generally, no. Most online PDF services, including Acrobat Online Services, do not support advanced font embedding or preflight features. You typically need a dedicated desktop PDF editor to perform these tasks.
How do I know if my PDF has unembedded fonts?
You can verify the font status by opening the document in a PDF reader, navigating to 'File' > 'Properties', and checking the 'Fonts' tab. Fonts that are properly included will say 'Embedded' or 'Embedded Subset' next to their names.
