Common Questions About PDF Redaction

What is the difference between redacting and just covering with a black box?

Simply covering content with a black box in a PDF editor can often be undone, as the original text or image data still exists underneath. True redaction, which our tool performs, permanently removes that data from the file, replacing it with an opaque block. It's a crucial security difference.

Can I undo a redaction after I apply it?

Before you click "Apply Redactions," you can use the "Undo Last" button to remove the last mark or "Clear Page" to remove all marks on the page. However, once you click the apply button and the process completes, the changes are permanent and cannot be undone in the downloaded file. This ensures the security of the redaction.

Will redacting a PDF reduce its quality?

No, the quality of the rest of your document will be perfectly preserved. Our tool only modifies the specific areas you choose to redact, leaving all other text, images, and formatting untouched and in their original quality.
