pdf.tocgen for Mac

pdf.tocgen is a collection of command-line tools for automatically generating tables of contents for PDF files. Many ebooks or scanned PDFs lack bookmark outlines, making it inconvenient to navigate between chapters, while adding entries manually one by one is time-consuming and laborious. By recognizing heading text and its typographic features in a PDF, it helps extract the chapter structure and write it back into the file as a clickable table of contents. It suits users who frequently work with long documents, technical manuals, or ebooks, especially those accustomed to working in a terminal and wanting to organize PDFs in batches. The entire toolset is built around the command line and requires no graphical interface; used together with scripts, it can complete repetitive table-of-contents organization work more efficiently.
