Redact PDF

Permanently redact sensitive information from PDFs. Text, images, and metadata in marked areas are completely destroyed — not just covered visually. True redaction via MUPDF.

Redaction is permanent and irreversible

The text, images, and vector content beneath each mark are permanently removed from the file — not just hidden. The rest of the document stays intact and selectable.

Frequently Asked Questions

What makes this "true" redaction?
Text characters and image data in the redacted areas are removed from the PDF's content stream — not just covered with a black box. The underlying data is permanently destroyed.
Can I redact text by searching for it?
Yes — use "Find & Redact" to search for text, SSN patterns, email addresses, or custom patterns. All matching instances are highlighted for redaction.
Is this reversible?
No. Redaction is permanent and irreversible. A two-step workflow (mark → confirm) prevents accidental redaction.
Can metadata also be removed?
Yes — the "Full Metadata Strip" option removes XMP metadata, document info, and embedded file attachments.
