About the How-to guides thread

Task-first guides. Each one answers a single question a person actually typed into a search box (how do I make a transparent PNG, how do I add captions, how do I get a video into the right format), and answers it completely, free, without asking anyone to install or sign up for anything.

The house rule for this cluster is that a how-to must survive contact with the failure cases. Anyone can list the happy path; these guides say what to do when the edge comes out ragged, when the file is too large, when the output looks wrong in one app and fine in another. That is usually where the reader actually is by the time they search.
