# PDFEdit general overview

This means that if you delete something from a document it can still be seen in the previous revision, and the file will not get smaller.

Pdf Editor allows simple manipulation of objects within the PDF structure, using a graphical and command-line interface and a powerful scripting language.

Changes to a document are added to it as a new revision so that old revisions can be viewed or saved as a new file . All PDF viewers have to display the content of the most recent revision. Though we don't know of any PDF viewer (except for PDFedit) which would enable also revision browsing.
