These guides are here because —just use a PDF tool— is not an answer when a job portal rejects a 3 MB file, a print shop asks for TIFF, or a contract needs a password before it leaves your outbox.

What belongs here

File formats, privacy, compression, accessibility, and the unglamorous parts of sharing documents. If a guide recommends uploading something sensitive to a random server, it doesn—t belong on this site.
