A proper redaction workflow needs to remove or rasterise the covered content, not simply place a decorative box on top. Keep an untouched source because redaction is intentionally destructive.
Zoom in before drawing a redaction box. Names, account numbers and signatures often sit closer to neighbouring text than they appear at first glance.
When Permanent redaction isn’t the right endpoint
Use Pixelate or ordinary drawing only for visual effects, not for confidential document redaction.
