Is it possible, using Adobe Acrobat or another tool, to globally replace a font in a PDF?
How can I do this?
Choose Tools > Edit PDF > Edit . The dotted outlines identify the text and images you can edit. Select the text you want to change. In the right-side Format panel, select a font, font size, or other formatting options.
Open the Find dialog (Ctrl or Cmd + F). Enter "XYZ". For the replace with use "ABC". Click "next" and then "replace" .
Go to Edit > Preferences > Content Editing > Font Options. Select an appropriate font in the Default font for Add Text drop-down list. Select an appropriate font size in the Font Size drop-down list. Click OK.
Without seeing your particular file it is hard to say that this would definitely work. But, typically a font is defined like this:
/Resources <<
/Font << /F13 1 0 R >>
>>
1 0 obj <<
/Type /Font
/Subtype /Type1
/BaseFont /Helvetica
>> endobj
The font resource is then used as /F13 12 Tf
wherever text is drawn with it.
If you were to change the /BaseFont
in the definition, it would affect all uses of that font resource.
You can upload a PDF to Google Drive, and then open it. Once opened, you'll see the option to "Open in Google Docs": click it.
After it's done loading, select all text (CTRL+A), and then change the font on the menu above to the one you want. After that's done, you can do File -> Download -> PDF. Google Docs will do its magick, and give you a PDF with the modified font. New pages will be automatically added if the fonts are different sizes.
