About Remove hidden data

Remove hidden data cleans a PDF before you send it. It removes the document details anyone can see in File › Properties (author, software, dates), scripts and actions that run by themselves, attached files, comments and highlights, saved page previews, private data left by the program that made the file, and earlier saved versions that can still hold text you deleted. The pages look the same, and the cleaned file is checked again before you download it. Everything runs on your device, so the PDF is never uploaded.
