Sanitize is important because it removes hidden information that redaction alone does not erase. This includes metadata, old edits, and invisible layers that may still contain private data. If you skip sanitizing, someone could find sensitive details even after redacting visible text. Always use sanitize to make sure your document is truly safe before sharing.

Redact only works on text or images you select.
If the scan is blurry, text may not be recognized as selectable.
You may need to use OCR (text recognition) first to make the text selectable before redacting.

No, the Adobe PDF Services API does not support redaction. You must use Acrobat Pro desktop for this task.
