Practical articles for the jobs people bring to a PDF: adding a signature, fixing a word, hiding an ID number, joining files and getting under a size limit.
A tool page explains what each button does. These guides cover the part around it: which option to try first, what to check before you send a file and where things usually go wrong.
Everything described runs in your browser, so the files you choose stay on your device. The date shown on each guide is its last update.
