Editing PDF

'''PDF''' can refer to one of two things, for /tg/ purposes:

* The [[Planetary Defence Force|'''P'''lanetary '''D'''efence '''F'''orce]], the speedbump used to delay the enemy until the [[Imperial Guard]] can arrive.
** There is also the [[Star Wars]] flavoured [[Planetary Defense Force (Star Wars)|Planetary Defense Force]].
** The term is somewhat generic in science fiction along with [[vidya|''Earth'' Defense Force]], but other spins on the acronym for similar styled armies also exist, like [[Grimdark Future]]'s ''Human'' Defense Force.
* A file format designed for printing out exactly what the author intended via computer, widely used nowadays for distributing books online, both legitimate and [[Pirate|piracy]]. There's some history and technical arglebargle about the file format that can be found [[wikipedia:Portable Document Format | at Wikipedia]].
**[[/tg/]] is one of token few boards on [[4chan]] that also allows for uploading PDFs in place of an image, especially useful for sharing rules, artbooks, and [[homebrew]] - though still hamstrung by the same upload limitations that have gone unchanged for years. This would bite 4chan in the ass during the April 2025 hack, as the hacker responsible claimed that [[Lolwut|the website did not properly check and validate if a file was actually a PDF]] (also confirmed by the [https://blog.4chan.org/post/781845918774394880/still-standing 4chan dev blog]  afterwards), allowing the hacker to run malicious code by uploading a PostScript file that used exploits in the website's [[EPIC FAIL|outdated-by-13-years]] version of GhostScript to gain [[Anal circumference|shell access]], fucking with the entire website until the plug got pulled. Since then, PDF support has been pulled entirely - [[Rage|with no word on it coming back]].
**May also be used as slang for [[Loli|pedophilia]] (since "PDF file" sounds similar to Pedophile) to get around filters.
