How to Redact a PDF So the Deleted Text Stays Deleted

Most redacted PDFs aren't redacted.

Open one, drag your cursor across a "redacted" paragraph, and the text is still there — selectable, copyable, pasteable. The black box is just paint. Anyone with two clicks can read what was hidden.

This happens more often than people think. Lawyers share contracts with client names "redacted" that lift right off. HR teams send salary letters with black bars over figures — figures that select cleanly underneath. The mistake is the same everywhere: covering text is not removing text.

Real redaction deletes the underlying content. A black box just covers it.

How to do it properly

1. Open the PDF in a tool that does true redaction — one that deletes the text and image data, not one that draws over it.
2. Mark the passages you want gone.
3. Export a new copy, then verify: try selecting the redacted area. If nothing selects, it's genuinely gone.

Why this matters for your workflow

Redaction is one of those tasks where "close enough" can be a liability. A contract, an offer letter, a medical report — the whole point of redacting is that the sensitive part stops existing in the shared copy. Anything less is decoration.

With PDFixel's PDF editor, the redaction tool removes the underlying text and images for good — the exported file contains no trace of what was there. And like every one of PDFixel's tools, file bytes are not uploaded for processing: everything happens locally in your browser, on your own device.

The rule is simple: if someone can select it, it isn't redacted.
