Frequently Asked Questions
What is redaction and how is it different from covering text?
Redaction permanently removes sensitive content from the PDF at the data level. Simply drawing a black box over text does not delete it—redaction does.
Is redaction reversible?
No. Proper redaction permanently removes the underlying data. Once applied and saved, the redacted content cannot be recovered from the output file.
What content can I redact?
You can redact text, numbers, images, signatures, and any other visible content on the page. Select the areas to redact and they will be permanently blacked out.
When should I redact a PDF?
Redact before sharing documents publicly, when hiding personal data in legal filings, or when distributing records that contain confidential financial or medical information.
Can I redact multiple pages at once?
Yes. You can select and redact content across multiple pages in a single session. Review each redacted area before saving, as the removal is permanent.
When to use this tool
Permanently remove sensitive text or images from a PDF by covering them with black rectangles. Redaction is irreversible: the hidden content cannot be recovered from the output file.
- Personal data such as names, addresses, or ID numbers must be hidden.
- A public copy of a document should conceal confidential figures.
- Legal or medical records need redacted versions for non-privileged review.
Tips for best results
- Always redact on a copy and keep the unredacted original securely.
- Double-check every redacted area before saving because the removal is permanent.
- Test the redacted PDF by trying to select text under the blacked-out areas.
