A black box drawn over text in most "redaction" tools leaves the words themselves sitting underneath it, selectable and copyable the moment the shape is removed. This instead turns every page that contains a match into a flattened image with the box burned into the picture — the words are actually gone from that page, not covered. Pages with no match are left exactly as they were, still text and still searchable.

No. The file is opened, changed and written by this browser tab — it is never sent to a server, so there is no queue to wait in and nothing to delete afterwards. Once the page has loaded you can turn the network off and the tool still works.
