Can You Convert PDF with Embedded Fonts to Non-Embedded Fonts Using Ghostscript?

If you've ever encountered issues with PDF documents that contain embedded fonts, you're not alone. Many users face challenges when trying to open these files in applications that do not support embedded fonts. This article addresses a specific query regarding converting PDF documents containing embedded fonts into versions with standard (non-embedded) fonts using Ghostscript.

Understanding the Problem

You may run into scenarios where your application cannot process PDFs with embedded fonts. This limitation can be frustrating, especially if you rely on specific features or integrations that demand standard fonts. When someone inquired about how to use Ghostscript for this conversion, they encountered a few challenges:

Command Attempts:

The first command produced a PDF that still had embedded fonts, rendering it incompatible with their application.

The second command resulted in a PDF that could not open, not just in their application, but even in Adobe Reader.

The Solution: Using Ghostscript Effectively

After researching alternative approaches, a successful solution emerged that involves modifying the Ghostscript command by using the -dNoOutputFonts option. This command effectively strips the embedded fonts from the PDF, thus enabling conversion to a version that uses standard fonts. Here's a breakdown of the command used and how you can implement it.

The Correct Command

The command that worked well for this conversion is as follows:

Explanation of the Command

Let's break down each component of the Ghostscript command:

-sDEVICE=pdfwrite: This tells Ghostscript to create a PDF file.

-dCompatibilityLevel=1.4: Sets the PDF version compatibility level.

-dPDFSETTINGS=/printer: Optimizes the PDF for better printing quality, which can enhance the output results.

-dNOPAUSE: Prevents Ghostscript from pausing after processing each page. This is useful for batch processing.

-dNoOutputFonts: This option is key. It instructs Ghostscript to avoid writing the embedded fonts, thus creating a file that effectively uses standard fonts instead.

-dQUIET: Reduces the amount of output provided during processing to keep the console clean.

-dBATCH: Allows Ghostscript to exit after finishing the job, ideal for automated scripts.

-sOutputFile=output.pdf: Specifies the name of the output file.

inputwithembeddedType1.PDF: This is the source PDF file containing the embedded fonts.

Why This Works

Using the -dNoOutputFonts option instructs Ghostscript to create a PDF without the embedded fonts, thus enabling increased compatibility with applications that do not support embedded PDF fonts. By following this command structure, users can bypass the limitations imposed by embedded fonts and achieve a more usable PDF file.

Conclusion

Converting a PDF with embedded fonts to one with standard fonts using Ghostscript can be accomplished effectively with the correct command. Whether you're dealing with embedded Type 1 fonts or facing application compatibility issues, incorporating the -dNoOutputFonts option is essential for successful conversion.
