How to Redact a PDF (Permanently Remove Sensitive Text)
Redaction gone wrong is a classic data leak: someone draws a black rectangle over a name, but the text underneath is still there and can be copied straight out of the file. Real redaction removes the underlying content. Here is how to do it safely.
The tool
PDF Redactor
Step by step
- Open the redactorGo to the PDF Redactor — redaction runs locally in your browser, so the document never leaves your device.
- Load your PDFSelect the PDF you need to sanitize.
- Mark what to removeSelect the text or areas to redact — names, account numbers, addresses, anything confidential.
- Export the clean fileExport the redacted PDF. The underlying text is permanently removed, not merely hidden.
Why a black rectangle is not enough
Drawing a shape over text in many PDF editors only covers it visually — the actual characters remain in the file and can be selected, copied, or extracted by anyone. True redaction deletes that content so it cannot be recovered. This tool does the latter.
Is my document private?
Yes — redaction is performed entirely in your browser, so the file never leaves your device and nothing is uploaded. That makes it well suited to sensitive documents like contracts, statements, and IDs.
Frequently asked questions
Is the redacted text really gone?
Yes — redaction permanently removes the underlying text rather than drawing over it, so it cannot be copied or recovered.
Does my PDF get uploaded?
No — redaction happens locally in your browser; your document never leaves your device.
Is it free?
Yes, with no sign-up. It runs on secure cloud servers and draws from a shared pool of 15 free cloud credits a day; Kitolity Pro and Pro Max add a larger monthly pool for heavier use.
