Open the PDF you want to redact in Adobe Acrobat Pro.

Best practiceIf you do not see 'Redact a PDF,' click 'View more' to expand the list of tools.
Use your cursor to select the text or images you want to redact.

You can preview all redaction marks before applying them to ensure nothing is missed.
This runs in the Acrobat app - there is no separate API for this task.
Redaction only removes visible content from your PDF. However, PDFs can store hidden data like metadata, comments, or previous versions. Sanitize removes all this hidden information. This ensures that no sensitive data remains in the document, making it truly secure before sharing.
| Feature | Black Rectangle | Redaction Tool |

| Visibility | Text is still present underneath | Text is deleted and replaced by a black mark |
For large documents with many instances of sensitive information like Social Security Numbers or account numbers, use Acrobat's pattern-based auto-redaction feature. This allows the software to find and mark all instances of a specific pattern automatically. After auto-redaction, it's a good practice to have another person review a random selection of the redacted areas to ensure accuracy and completeness.
