Features
Text Is Removed, Not Covered: Most tools draw a black rectangle and save. The characters stay in the content stream, so anyone can select them, run pdftotext, or delete the rectangle — this is how redaction failures make the news. Any page with a match is re-rendered as an image instead, so the text no longer exists in the file.
Reports What It Removed: You get a match count and the page numbers it touched, because the difference between "there was nothing to find" and "the search missed it" matters enormously here.
Only Affected Pages Change: Pages with no matches pass through untouched and keep their selectable text and small file size. Only pages that needed redacting become images.
Nothing Leaves Your Device: The document never reaches a server. For a tool handling exactly the material you least want disclosed, that is the whole point.
Frequently asked questions
Why does the redacted page stop being selectable?
Because that is what makes the redaction real. The page is re-rendered as an image, which removes the underlying text along with the part you wanted gone. It is a deliberate trade: a searchable page would mean the characters were still in the file.
Could it miss something?
Yes, and you should assume it might. Matching happens inside each run of text the PDF reports, and a document can split a word across runs through kerning or font subsetting. Always open the result and check. The match count is there so a suspiciously low number is obvious.
Is a black box in another tool good enough?
No. If a tool only draws a rectangle, the text is still there — selectable, searchable, and recoverable by deleting the shape. Several well-documented leaks of court and government filings happened exactly that way.
Does the file get bigger?
Usually yes, because affected pages become images rather than text. That is the cost of the text actually being gone.
