  • understand pdf file structure and object syntax
  • build a simple pdf file from scratch in a text editor
  • learn how pdf encryption and permissions work
  • process pdfs from the command line with pdftk
  • read a chinese translation of pdf explained

When to choose

  • you want a beginner-friendly introduction to the PDF format
  • you prefer reading in Chinese
  • you are a programmer or professional needing hands-on PDF internals knowledge

When to avoid

  • you need a PDF manipulation library or tool rather than a book

  • you need up-to-date PDF 2.0 coverage
