Is the redacted text permanently unrecoverable?

Yes. The tool deletes the underlying character codes and vector glyphs beneath the redaction box, ensuring data cannot be recovered by copying or selecting.

Why is drawing a black shape in basic PDF viewers insecure?

Basic PDF editors often place a black rectangle *on top* of the text, leaving the raw text selectable beneath it. Our tool permanently destroys the underlying text stream.

Can I add redaction reason codes (e.g., 'FOIA Exemption b4')?

Yes. You can optionally overlay standard FOIA/privacy exemption codes on top of the black redaction bars.

Does redaction remove hidden text layers in scanned OCR documents?

Yes. The invisible OCR text layer within the redacted bounding box is completely erased along with the visible image pixels.

Are confidential legal files uploaded to any server?

No. All redaction operations execute 100% client-side in your web browser memory.

How do I permanently blackout sensitive Social Security, financial, or medical data in a PDF?

Select the Redaction tool and draw black redaction boxes over sensitive personal details (SSNs, bank accounts, medical records). Click 'Apply Permanent Redaction' to destroy the underlying character streams and rasterize the blackout area permanently.

Does PDF redaction comply with legal and FOIA privacy standards?

Yes. Because both visual pixels and underlying PDF vector text layers are permanently excised from the document stream, the redacted data cannot be uncovered using search, inspect, or clipboard copying.
