- Scenario
- Optimizing or reducing the file size of a PDF document that contains text formatted in the Century Gothic font.
- Observed behavior
- The Century Gothic text becomes corrupted or substituted because the font is automatically unembedded during the PDF size reduction process.
Ensure you have a backup copy of your original, uncompressed PDF file before applying any optimization workflows, so you do not permanently lose the original font data.
Use the Optimized PDF Workflow to Retain Embedded Fonts
Use the advanced PDF Optimizer tool instead of the standard 'Reduce File Size' option to explicitly prevent fonts from being unembedded during compression.
Standard file size reduction features often strip out font data to save space. By using advanced optimization workflows, you can specify exactly which fonts to keep embedded, ensuring that specialized fonts like Century Gothic display correctly on any device.
Open your PDF file. Navigate to 'File', select 'Save as Other', and then choose 'Optimized PDF' to launch the PDF Optimizer dialog box.
In the left-hand panel of the PDF Optimizer window, click on the 'Fonts' category to view the font embedding options.
Check the box labeled 'Do not unembed any fonts'. Alternatively, find Century Gothic in the list of embedded fonts and ensure it is moved to the 'Retain' list.
Click 'OK' to apply the optimization settings. Save the new PDF document, and the file size will be reduced without corrupting the Century Gothic text.

Frequently Asked Questions
Why do fonts change when I reduce a PDF file size?
Standard file size reduction tools often unembed fonts to minimize the file's footprint. If the computer or device opening the compressed PDF doesn't have the original font installed, it will substitute it with a default system font, altering the document's appearance.
What does it mean to embed a font as a subset?
Subsetting a font means the PDF only saves the specific characters (letters, numbers, symbols) that are actually used in the document, rather than attaching the entire font file. This dramatically reduces the PDF file size while guaranteeing the text displays flawlessly.
Can I fix my PDF if the Century Gothic font is already corrupted?
Once a font is completely unembedded and the file is saved, the exact font data is lost from that specific file. You will need to reopen your original, uncompressed source document and compress it again using the correct 'Retain fonts' settings.
