Question :I'm aware of the some utility that can indicate which fonts are used by a PDF, and whether they are embedded or not. Now the problem: given I had PDF files with embedded fonts -- how can I extract those fonts in a way that they are re-usable as regular font files?
Are there preferably free tools which can do that? Also: can this be done programmatically with,is there any solution on VeryPDF? What do I exactly need to type into command prompt window?

Extract embedded PDF fonts to an external ttf file using some utility or script. Update: Jul Recent versions of mupdf have seen an internal reshuffling and renaming of their binaries, not just once, but several times. The main utility used to be a 'swiss knife'-alike binary called mubusy name inspired by busybox?
These support the sub-commands info , clean , extract , poster and show. Unfortunatey, the official documentation for these tools isn't up to date yet.
If you're on a Mac using 'MacPorts': then the utility was renamed in order to avoid name clashes with other utilities using identical names, and you may need to use mupdfextract. To achieve the roughly equivalent results with mutool as its previous tool pdfextract did, just run mubusy extract Downloads are here: mupdf. Then, Ghostscript can also extract fonts directly from PDFs. However, it needs the help of a special utility program named extractFonts.
Now use it, you need to run both, this file extractFonts. Ghostscript will then use the instructions from the PostScript program to extract the fonts from the PDF. I've tested the Ghostscript method a few years ago. I don't know if other font types will also be extracted at all, and if so, in a re-usable way. I don't know if the utility does block extracting of fonts which are marked as protected. Finally, Didier Stevens' pdf-parser. It can also decompress and extract arbitrary streams from objects, and therefore it can extract embedded font files too.
But you need to know what to look for. Let's see it with an example. I have a file named big. Object no. To look specifically at PDF object no. This pdf-parser. To dump any stream from an object, pdf-parser. Let's do it:. Our extracted data dump will be in the file named dumped-data. Let's see how big it is:. Oh look, it is 1. We saw this figure in the previous command's output. Opening the file with a font reading tool like otfinfo this is a part of the lcdf-typetools package will lead to some disappointment at first:.
OK, this is because we did not yet let pdf-parser. For this we have to add the -f parameter:. Oh, look: that exact number was also already stored in the PDF object no. So Bingo! Given the size of this file We could rename it to arial-regular. FontForge will automatically detect and show a list of all the fonts used in the PDF file.
Double click on any font to generate a character set for that particular font which you can then save to your hard drive. When you are uncertain, it is better to take what is already working and use it in your own work. Saves a lot of time and effort.
