- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Editing text in a PDF and trying to select a specific custom font.
- Observed behavior
- The A Caslon Pro font does not appear in the font list within Acrobat, preventing the user from using it.
Ensure you have the valid A Caslon Pro font file downloaded to your computer and verify that the PDF document you are trying to edit does not have restrictive security permissions.
Install the Font Locally and Restart Acrobat
Acrobat relies on your system's installed fonts. Installing the font at the OS level ensures it appears in Acrobat's font list.
If a font is not installed on your operating system, Adobe Acrobat cannot use it for editing, even if it is embedded for viewing. You must install the font locally and refresh the application.
Find your downloaded A Caslon Pro font file (usually ending in .ttf or .otf) on your local drive.
Right-click the font file and select 'Install' or 'Install for all users' on Windows. On a Mac, double-click the file and click 'Install Font' in the Font Book window.
Completely close Adobe Acrobat and reopen the PDF document so the application can scan your system for newly installed fonts.
Select the 'Edit PDF' tool, highlight the text you wish to change, and select 'A Caslon Pro' from the Format panel's font dropdown menu.

Verify Font Compatibility and Integrity
Check if the font file is corrupted or unsupported by testing it in other applications.

Frequently Asked Questions
Why does a font appear in Word but not in Acrobat?
Some font formats may lack the correct embedding permissions required by Acrobat for editing. Restarting Acrobat after installation usually resolves temporary detection issues.
How can I tell if A Caslon Pro is already embedded in my PDF?
Open the PDF in Acrobat, go to File > Properties, and click the Fonts tab. If A Caslon Pro is listed with '(Embedded)' next to it, the font data is stored within the document itself.
Can I use downloaded fonts in PDFs without installing them?
No, to actively edit or add new text using a specific custom font like A Caslon Pro, the font must be physically installed on your computer's operating system.
