Also: can this be done programmatically with, say, iText? You have several options. However, be aware that most PDFs do not include to full, complete fontface when they have a font embedded. Mostly they include just the subset of glyphs used in the document. Another method is to use the Free font editor FontForge :. Check the FontForge manual. You may need to follow a few specific steps which are not necessarily straightforward in order to save the extracted font data as a file which is re-usable.
Next, MuPDF. This application comes with a utility called pdfextract on Windows: pdfextract. Update: Newer versions of MuPDF have moved the former functionality of 'pdfextract' to the command 'mutool extract'. Download it here: mupdf. This command will dump all of the extractable files from the pdf file referenced into the current directory. Generally you will see a variety of files: images as well as fonts.
The image names will be like img CFF Compact Font Format files are a recognized format that can be converted to other formats via a variety of converters for use on different operating systems. Again: be aware that most of these font files may have only a subset of characters and may not represent the complete typeface. 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.
In any case you need to follow the license that applies to the font. Pirating fonts is like pirating any software or other copyrighted material. Most PDFs which are in the wild out there do not embed the full font anyway, but only subsets. Extracting a subset of a font is only useful in a very limited scope, if at all. No need to install anything. Worked a treat, so happy. Even though this question is 10 years old, it is still valid and as technology changes so does a valid answer.
In searching the current answers noticed none of them note WOFF Web Open Font Format W3C Wikipedia which can be used to recreate the individual characters glyphs and display them in a web page accurately.
In the resulting zip will be a font directory of woff file types. Current Internet browsers support woff files if you were not aware. PS, I will probably update with more info as I learn more about using woff file types, but as this is creative commons, feel free to edit this answer if you have something of value to pass along.
It produces OpenType. PDF2SVG is a commercial product, but you can download a free demo executable which includes watermarks on the SVG output but doesn't otherwise restrict usage. This is a followup to the font-forge section of Kurt Pfeifle's answer , specific to Red Hat and possibly other Linux distros. Learn more. How can I extract embedded fonts from a PDF as valid font files? Ask Question. Asked 9 years, 9 months ago. Active 5 months ago.
Viewed k times. Kurt Pfeifle Active Oldest Votes. Now fonts will be embedded in. You may need to convert the. In PDFs there are never. Without these, font files are hardly usable in a visually pleasing way. Then select "Extract from PDF" in the filter section of dialog. Select the PDF file with the font to be extracted. A "Pick a font" dialogbox opens -- select here which font to open.
Using pdf-parser. To show this more clearly: pdf-parser. Let's do it: pdf-parser. Let's see how big it is: ls -l dumped-data. 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: otfinfo -i dumped-data. For this we have to add the -f parameter: pdf-parser. What does file think it is? All Rights Reserved.

Caveats: In any case you need to follow the license that applies to the font. Pier Paolo Ramon 1, 16 16 silver badges 21 21 bronze badges. Kurt Pfeifle Kurt Pfeifle If you are on Mac and install mupdf from ports or perhaps from binary too , the extraction too is called mupdfextract.
The Final Output, Generating Font Files
Although you can do a wide range of testing within FontForge itself, you will need to generate installable font files in order to perform real-world testing during the development process. In addition, your ultimate goal is, of course, to create a font that you can make available in an output format for other people to install and use. You will use the Generate Fonts tool found in the File menu to build a usable output font regardless of whether you are making it for your own testing purposes or to publish it for consumption by others, but you will want to employ a few extra steps when building the finished product. FontForge can export your font to a variety of different formats, but in practice only two are important: TrueType which is found with the. Technically the OpenType format can encompass a range of other options, but the CFF type is the one in widespread use. To build a font file for testing purposes — such as to examine the spacing in a web browser — you need only to ensure that your font passes the required validation tests. Be sure to save your work before you proceed any further, though: some of the changes required to validate your font for export will alter the shapes of your glyphs in subtle ways.
Extract all fonts inside a PDF file
The Font Info dialog is available from all views. It allows you to name your font and various other useful bits of information. In a CID keyed font , things are more complex. Each CID keyed font is composed of man sub-fonts; this command works on the current sub-font while there is a separate command to access the information for the font as a whole — that dialog looks the same.
