What is 'true' PDF redaction?

Unlike simple black markers that only overlay a shape, true redaction physically deletes the text characters, vector objects, and image pixels underneath the box, preventing anyone from extracting the text.

How can I redact a PDF for free?

Upload your PDF, draw your blackout boxes over the text you wish to hide, click Redact PDF, and download. It is 100% free on OptaPDF.

Is the redacted content copyable after download?

No. Our backend engine uses PyMuPDF's advanced redaction features to erase underlying characters and paths completely. The data is gone.

What is the naming rule for redacted PDFs?

The output file will follow our standard naming rule, e.g., x_redacted.pdf.
