Remove content from a PDF for good. Drag across anything that should not be in the document, and it stops existing, rather than being covered by a rectangle that anyone can select underneath.

Questions

Is this different from drawing a black box over the text?
Completely. A black rectangle drawn over text in a PDF hides nothing: the words are still objects in the file and can be selected, copied or read with a parser. That is why names keep appearing in supposedly redacted documents. Here the page is turned into a picture of itself, so what was underneath is gone.
What do I lose by redacting a page?
That page stops having selectable text or working links, including the parts you did not mark, because the whole page becomes an image. Pages you left alone are untouched.
How do I know it worked?
The result is checked before it downloads: the finished document is reopened and the redacted pages are confirmed to carry no text at all. If any still does, nothing is downloaded and the page tells you which.
