# Lightweight cleaning

By default, the removal process might alter a bit the data of your files, in order to remove as much metadata as possible. For example, texts in PDF might not be selectable anymore, compressed images might get compressed again…

The lightweight mode, while not as thorough, will not make destructive changes to your files.
