Redaction permanently removes sensitive information from a PDF — social security numbers, financial data, personal addresses, confidential business terms. Unlike simply drawing a black box over text, true redaction deletes the underlying data so it cannot be recovered.
Why True Redaction Matters
A common mistake is using a black rectangle annotation to "hide" text. While this looks redacted on screen, the original text is still in the file and can be easily extracted with basic PDF tools. This has caused major data breaches in government and legal contexts.
True redaction permanently removes the selected content from the PDF file. The text is deleted from the document structure — there is no way to recover it. Only true redaction provides real data protection.
Redact with PDF Alone
Upload your PDF to PDF Alone's Redact PDF tool. Select the text, areas, or images you want to permanently remove. The tool replaces the selected content with black bars and removes the underlying data from the file.
After redaction, verify the result by trying to select or search for the redacted text — it should be completely gone, not just hidden behind a black box.

Financial information: Bank account numbers, credit card numbers, salary figures, tax IDs.
Legal content: Privileged attorney-client communications, confidential settlement terms, sealed court records.
Business data: Trade secrets, internal pricing, employee names in HR documents, confidential client information.
