Protect Confidential Information Before Sharing

Whether you need to conceal social security numbers, bank account details, home addresses, or confidential contract terms, our PDF Redaction tool lets you permanently black out sensitive zones before sending documents to third parties.

True Permanent Client-Side Redaction

Unlike simple markup tools that just float a removable black box over text, A2Z PDF burns permanent blackout rectangles into the document canvas so privacy is guaranteed.

Frequently Asked Questions

Is the redaction permanent?

Yes. When you redact text or regions, solid black boxes are permanently drawn over the coordinates in the downloaded PDF file.

Can someone remove the black box to see what was underneath?

No. Our tool embeds solid filled shapes directly into the PDF content stream so the underlying visual information in those redacted zones is obscured.

Why is local redaction safer than cloud redaction?

When redacting sensitive banking, legal, or medical records, uploading unredacted originals to cloud servers creates security risks. Client-side redaction ensures the original never leaves your device.
