Redact Aadhaar, PAN and account numbers from a PDF
The mistake almost everyone makes when hiding something in a PDF is drawing a black rectangle over it. It looks convincing and it hides nothing: the text is still in the file underneath the shape, and anyone can select it, copy it or extract it with a free tool. Documents have leaked this way repeatedly. Real redaction removes the text from the page content rather than covering it.
That is what happens here. You choose the categories that matter, such as Aadhaar numbers, PAN, phone numbers, email addresses, bank account numbers and card details, and can add specific words or names of your own. Matches are validated rather than merely pattern matched, with Aadhaar and card numbers checked against their checksums, which avoids mangling an invoice number that merely looks like an account number. The text is then taken out and the page is flattened, so there is nothing left behind to recover.
Two practical notes. A scanned document contains no text to find, so run OCR first or the search will come back empty even though you can see the numbers on screen. And flattening means a redacted page is no longer searchable, which is the unavoidable cost of making sure the removed content is genuinely gone. Always open the result and check it before you send it.

Get a better result
Matches are checked rather than merely pattern matched, with Aadhaar and card numbers validated by their checksums, which keeps false positives down. Pages containing a match are flattened so the removed text cannot be copied back out.
Know how your file is handled
Redaction runs on our server because flattening and rewriting page content needs tooling unavailable in a browser. The file is transferred securely and deleted once your download has been produced.
Check before you share
Only text the PDF actually contains can be found, so a scanned page needs OCR first. Redacted pages are flattened, which means they are no longer searchable afterwards.
Questions people ask
Redact PDF FAQ
What is detected, whether the data is really gone, scanned documents, and checking the result.
How do I redact a PDF properly?
Upload the document, choose which categories of data to remove and add any specific words, run the redaction, then open the downloaded file and confirm the information is gone before sharing it.
Is drawing a black box over text the same thing?
No, and this is the single most important point. A black rectangle is a shape drawn on top of text that is still in the file, so the hidden words can be selected, copied or extracted. Redaction removes the text itself.
Can the redacted text be recovered?
No. The matched text is taken out of the page content and the page is then flattened, so there is no hidden layer left holding the original characters.
What kinds of data can it find?
Aadhaar numbers, PAN, phone numbers, email addresses, bank account numbers and card details, plus any specific words or names you add yourself.
Why does it not find the numbers in my document?
Almost certainly because the PDF is a scan, so the page holds an image and there is no text to search. Run OCR PDF first and then redact the searchable version. OCR PDF
Will it redact things it should not?
Matches are validated rather than guessed from shape alone, and Aadhaar and card numbers are checked against their checksums, which keeps false positives low. Reviewing the result is still worth the minute it takes.
Why is the redacted page no longer searchable?
Because flattening is what guarantees the removed text cannot be recovered. It is a deliberate trade: a searchable page would mean leaving a text layer in place, which is exactly what you are trying to avoid.
Does the document I am redacting leave my computer?
Yes. Rewriting and flattening page content needs tooling that cannot run in a browser, so the file is processed on our server securely and removed once your download is ready.
Should I redact or just delete the page?
Delete the page when nothing on it is needed, since that is simpler and equally final. Redact when the page has to be shared but specific details on it must not be. Remove Pages
Can I redact a name or a specific word?
Yes. Add the words you want removed alongside the categories, which is how people handle names, addresses, client references and internal project codes.
