File how-to guides
Practical fixes for the PDF and photo problems that tend to block an upload or a deadline: files that will not open, files that are too large, pages in the wrong order, and photos that reveal more than you meant to share. Each guide explains the cause, the order of steps and how to check the result, and points to a FileLivo tool only where it helps.
