Tobias writes about moving files between phones, apps and computers: posting to social feeds, sending through chat apps, opening archives and getting phone video down to a size that uploads. He explains what apps do to files without saying so, such as re-compression, cropping and renaming, and how to plan around it. Platform limits are linked to the platform's own help pages and dated, since they change often. Each guide shows when it was last reviewed.
