FAQ
How is this different from drawing a black rectangle?
A drawn rectangle only covers the text; it is still in the file and can be copied. Here every page is re-rendered as an image, so the text no longer exists.
Can the redaction be undone?
No, and that is the point. Keep the original elsewhere if you need it.
Why is the export larger than the original?
Rasterised pages at 2x are usually bigger than vector content.
