How do I make sure redacted text is truly gone and not just covered?

Use the 'Redact text and images' tool, not just a black rectangle. After applying redaction, save the document. Then, try to select the area where the text was. Also, use the search function in Acrobat to look for the words you redacted. If you cannot select or find the words, the redaction worked correctly.

Redaction permanently removes the selected content from the document, making it unrecoverable. Drawing a black box only covers the content visually; the text or image still exists underneath and can be revealed by selecting and copying it. Always use the Redact tool for true data removal.

No, redaction only removes visible content. Hidden data, such as metadata, layers, or revision history, must be removed separately. After you redact, you should run the 'Sanitize' tool in Acrobat. This tool specifically cleans up hidden information, ensuring your document is fully private.

Redaction is permanent. Once you save a redacted document, the original content is gone forever. Working on a copy ensures you always have the unredacted original if you make a mistake or need the full document later. This protects your data and workflow.

Yes, for bulk Personally Identifiable Information (PII) like social security numbers or account numbers, Acrobat Pro offers pattern-based auto-redaction. You can set up patterns to find and mark these specific types of data throughout your document. After the automatic redaction, it is a good practice to have another person check a random sample to ensure accuracy before saving.
