If my PDF scan is blurry or has handwriting, will Redact in Acrobat Pro still work?

Redact works best on clear, typed text and images. If the scan is blurry or has handwriting, Acrobat may not recognize the text. You may need to use the image redaction tool to cover these areas. Always check by copying, searching, and looking at the redacted spots.

Redaction means hiding or removing private information from a document so others cannot see or recover it. In PDF files, redaction is important because sensitive data like names, numbers, or prices can be hidden under black boxes if not properly removed. True redaction makes sure no one can find this information, even if they try to copy or search the document. This protects privacy and keeps your organization safe from sharing secrets by mistake.
