What is the difference between PDF redaction and covering text with a black box?

Redaction permanently deletes the underlying content from the PDF file. A black-box overlay only hides content visually — the original data still exists and can be extracted. Our tool performs true redaction for real security.

Can redacted content be recovered?

No. Redaction is permanent and irreversible. The content is completely removed from the PDF data, not just hidden. Always keep a backup of the original document before redacting.

Is this tool suitable for GDPR compliance?

Yes. Permanent redaction helps meet data privacy regulations by completely removing personally identifiable information (PII) from documents before sharing or publishing.

Are my files uploaded to a server during redaction?

No. All redaction processing happens 100% in your browser. Your sensitive documents never leave your device, providing maximum privacy.

What types of content can I redact from a PDF?

You can redact text, images, and specific page areas. Draw rectangles over any content you want to permanently remove, then apply redaction to all selected areas.
