How to Redact Sensitive Text From a PDF
Published September 3, 2026 · 3 min read
A common but risky mistake is "redacting" a PDF by drawing a black box over sensitive text in a PDF editor — the original text is often still selectable underneath. Real redaction has to remove the text itself, not just hide it visually, which is what this tool does by rasterizing and covering matching content permanently.

Frequently asked questions
Yes, significantly — a drawn box in a typical PDF editor leaves the underlying text intact and selectable; this tool actually removes the matching content, not just covers it visually.
Yes — regex mode lets you match patterns like phone numbers or account formats, not just literal text you type out.
Only the matched terms are rasterized and blacked out; the surrounding text and layout stay as they were.
Because true redaction requires irreversibly altering the page content, doing this in your browser means the sensitive original never has to be uploaded anywhere to be cleaned up.
