Remove it.
Nothing left
underneath.

Almost every redaction app draws a black rectangle over the words. The words are still in the file. Anyone can copy them straight back out.

How it works

It finds them

Open a PDF and HyperRedact reads every page for names, ID and national insurance numbers, account and card numbers, addresses and dates — and counts how many times each one appears.

You choose

Nothing is removed until you tick it. Search a name or a number to catch every match at once, or press and drag across the page to add one by hand.

It proves it

The finished file is re-opened and searched for every term you removed. If a single one can still be read back, you are told.

Why a black box is not a redaction

A PDF keeps its text as text. Drawing a filled rectangle on top adds a shape to the page; it does not touch the sentence beneath. Select the area, copy, paste — and there it is. Court filings, police reports and bank statements have all leaked this way.

HyperRedact does not draw over anything. It renders each page, paints out the areas you marked, and rebuilds the document from those images. The page that comes out holds no text objects at all, so there is nothing underneath to recover.

It also flattens any invisible OCR layer the file was carrying, which is the other place redacted text tends to survive.

What you get back

  • A PDF with the marked text absent, not hidden.
  • A check run on the written file, not on the draft in memory.
  • Scans and photographs handled the same way — mark the area, it is painted out of the image.

It never leaves your phone

There is no server. Your document is opened, redacted and written on the device, and HyperRedact keeps no copy of it after you close the app. No account, no sign-in, no upload.
