Don’t take our word for it
Most tools that “redact” a PDF just draw a black box over the text. The text is still in the file underneath, and anyone with a free command-line tool can pull it back out in seconds. That’s the mistake that exposed Paul Manafort’s court filing in 2019.
Real Redact removes the text. There is nothing left underneath the bar. Here’s a real example, and the exact commands so you can check it yourself.
The example: a filled-in IRS W-9
We took a tax form (an IRS W-9) filled out with the name Jane Q. Testperson, and redacted that name with Real Redact. Download both versions and test them:
Both are synthetic test documents. “Jane Q. Testperson” is not a real person and there is no real personal data in either file.
Check the original — the name comes right out
pdftotext is a free tool that extracts the text from a PDF. Run it on the before file and the name is right there:
pdftotext w9-before.pdf - | grep -i "Jane"
Jane Q. Testperson ← the name pulls straight outNow check the redacted file — nothing
Run the same tools on the after file. We try three different ways to dig the name back out, including expanding every compressed stream inside the PDF and scanning the raw bytes. Every one comes back empty:
# 1. Extract the visible text:
pdftotext w9-after-redacted.pdf - | grep -i "Jane"
(no output)
# 2. Expand every compressed stream and search the raw PDF structure:
qpdf --qdf --decode-level=all w9-after-redacted.pdf - | grep -ai "Testperson"
(no output)
# 3. Scan the raw bytes for any leftover trace:
strings w9-after-redacted.pdf | grep -i "Testperson"
(no output)The form is otherwise untouched — open the redacted file and it’s still a perfectly readable W-9, just without the name. The text wasn’t covered up. It was removed.
What this does and doesn’t prove
This proves the core mechanism: when Real Redact removes a piece of text, it is genuinely gone from the file — not boxed over, not hidden, not recoverable with these tools.
What it can’t prove is that any tool will catch everything in every document. No redaction tool can promise that — scanned pages, handwriting, unusual fonts, and information you didn’t mark can all slip through. That’s exactly why the app reminds you to open and review the saved file before you share it. Real Redact does the removal honestly; the final check is still yours.
