How to corrupt a PDF on purpose

Need a file that looks like a real PDF but won't actually open? This tool selectively damages a PDF's structure so it triggers a "file is damaged" error in any reader.

Useful for testing your error-handling code or for the rare case when you need to send a deniably-broken file. Don't use it to deceive anyone you owe a working document.
