How to Fix the Cannot Extract Embedded Font Error in PDF
Question details
The user needs to resolve an error where a PDF viewer warns that it cannot extract an embedded font, leading to missing characters or printing failures.
- Product
- Device & OS
- not provided
- Scenario
- Opening or printing a PDF file that contains improperly embedded or corrupted fonts.
- Observed behavior
- An error message appears stating that the embedded font cannot be extracted, and some text may display as blank spaces or fail to print correctly.
Verify if the PDF displays and prints correctly despite the warning; if no characters are missing, the error can safely be ignored.
Run the Preflight Font Fixing Profile
Use Adobe Acrobat Pro's Preflight feature to automatically detect and fix potential font embedding issues and corrupted encoding tables.
This error often occurs when the creator software improperly embeds fonts, misidentifies them (e.g., TrueType vs Type 1), or includes corrupted encoding tables. The Preflight tool can often repair these structural issues natively.
Open the problematic PDF in Acrobat Pro DC and navigate to the Preflight tool.
Locate the 'Fix Potential Font Problems' profile, which is usually found within the Acrobat Pro DC 2015 Profiles group.
Run the profile to repair the font tables, then carefully review the corrected file to ensure all text displays properly.
Regenerate the PDF with Properly Embedded Fonts
If you are the author or have access to the original creator, regenerating the PDF from the source file is the most reliable way to eliminate font corruption.
Re-authenticate the Source Software
For PDFs exported from software like Adobe InDesign, licensing or authentication glitches can sometimes block proper font embedding.

Frequently Asked Questions
Why does the 'cannot extract embedded font' error occur?
This typically happens when the software that created the PDF improperly embeds the fonts, misidentifies font types (such as labeling a Type 1 font as TrueType), or includes corrupted encoding tables.
Can I ignore the embedded font extraction warning?
Yes, if the PDF displays all text correctly and prints without any missing characters or blank spaces, the warning is usually harmless and can be safely ignored.
Does the 'Use Local Fonts' option fix this issue?
In most cases, selecting 'Use Local Fonts' does not resolve extraction errors caused by corrupted encoding tables or bad embedding by the original creator tool.
How do I prevent this error when creating PDFs?
Ensure your creating software is up-to-date, verify that your system fonts are not corrupted, and explicitly check the 'Embed all fonts' setting during the PDF export or save process.
