Build images into a PDF and extract pages back out, pack files into a ZIP, turn a file into Base64 and back. Nothing is uploaded to a server.
This section handles jobs where a file needs repackaging rather than editing: collecting several shots into one PDF to send, splitting a document back into images, zipping a set of files, or getting a string representation of a file to paste into code. These operations usually involve documents and personal data, so the tools here work locally in the browser: the contents are never sent to a server and never persist after the tab closes.
