Redaction
Permanently removing content from a PDF — text, images, metadata — so it can’t be recovered, not just covered up.
Drawing a black box over text hides it on screen, but the text is often still in the file and can be copied out. True redaction removes the content itself.
In PDF-SDK
PDF-SDK does not redact. Remove information permanently with a redaction tool before you share a document.
