Why redact PDF?

Simply drawing black rectangle in Word does not remove text – anyone can copy behind it. True redaction permanently removes that area and replaces with solid color. Offices redact client data before sharing reports. Lawyers redact personal info from legal documents. Students redact roll numbers or personal details from certificates before posting online. Government forms require redacting sensitive IDs. This tool does real flattening, not fake covering.

Black vs White redaction

  • Black: Most common for confidential – clearly shows something was hidden, professional for legal
  • White: Clean look – hides without black marks, good for removing extra text and making document clean
