about this task

If you cannot select or find the text, the redaction was successful.

Redacting content with the Redact tool permanently removes the text or image. Covering it with a black rectangle only hides it visually; the original content is still there underneath and can be copied or searched. Redaction makes sure the information is truly gone.

Redaction only removes visible content. A PDF can also contain hidden data like metadata (author, date), layers, or revision history. This hidden data might still contain sensitive information. Sanitizing the PDF removes all this hidden data, ensuring no private details are left behind beyond what you redacted visually.

For large documents with many instances of specific patterns like SSNs or account numbers, use Acrobat's pattern-based auto-redaction feature. This allows the tool to find and mark all instances automatically. After auto-redaction, have another person review a random sample of the document to ensure all sensitive information was correctly redacted and nothing was missed.

No, the Adobe PDF Services API does not have a redaction operation. Redaction is a feature that is only available in the Acrobat Pro desktop application. You cannot automate the redaction process through the API.
