A collection of experiments demonstrating that PDF files can contain JavaScript and interactive behavior, most famously a playable Breakout game inside a PDF that works in Chrome. It serves as a demonstration and educational resource about the surprisingly powerful PDF specification.
Use cases
- play breakout inside a pdf file
- learn what javascript can do inside pdf documents
- demonstrate pdf security risks to a team
- understand the pdf specification's scripting features
- find examples of interactive pdf hacks
When to choose
- you want a concrete, working demo of JavaScript-driven behavior inside PDFs
- you are researching or teaching about PDF format capabilities and attack surface
- you want to reproduce the Breakout-in-a-PDF hack
When to avoid
- you need a production PDF generation or manipulation library
- you need a maintained tool with a license and ongoing support
- you need PDF features that work across all readers including Acrobat and Foxit
