What Redaction Actually Does
Proper PDF redaction permanently deletes the selected information from the file. The black box you see isn't a cover — the underlying data is gone. This is critical for legal, compliance, and privacy purposes.
Redaction vs. Black Box — Critical Difference
- ✓ True redaction: Underlying text/data is permanently deleted from the file. Cannot be recovered.
- ✗ Black box overlay: Original text remains in the file beneath the black rectangle. Can be copied, selected, or seen by removing the overlay.
PDF.it's redaction tool performs true redaction — the data is deleted, not hidden.
How to Redact a PDF (Step by Step)
Upload your PDF
Go to pdf.it.com/pdf-redaction and upload the PDF containing the sensitive information. Works with text-based PDFs and scanned documents.
Select text or areas to redact
Click and drag to select the text or image areas you want to remove. You can select multiple areas across multiple pages. The selected areas are highlighted to show what will be redacted.
Apply the redaction
Click Apply Redaction. The selected content is permanently removed and replaced with a solid black box. The original text no longer exists in the file.
Download and verify
Download your redacted PDF. Open it and try to select text in the redacted areas — you won't be able to, confirming the data has been removed.
