Why these are here
Every tool on this site answers "how do I convert X to Y". These pages answer the questions that come before that: whether uploading a file somewhere is a problem, why an operating system refuses to open a photo, and what your options are when you would rather not send a document to a stranger's server. Where the honest answer is "use the feature already built into your computer", that is what they say.
