Description

I am using pdfbox-2.0.24 to merge multiple PDFs. However, the merged file size is too large because it contains many duplicate embedded subsets of font. For an example, I merge 1.pdf and 2.pdf which shows some repeated font list as picture1. 

 

I tried the source code provided by mkl : How to reduce the size of merged PDF/A-1b files with pdfbox or other java library - Stack Overflow

 

However, it is not working for me. Can anyone have an idea to remove the duplicate embedded subsets of font in merging PDFs?
