How to convert Type 3 font to Type 1 font in PDF – Stack Overflow

I was able to “convert away” the Type 3 fonts in a PDF figure by opening the file in Adobe Acrobat Pro, and then printing the file to Adobe PDF (a virtual printer provided by Adobe Distiller, part of the Professional suite). I’m using the Adobe Pro suite version 11 (ca 2012), but newer versions presumably can do the same.
