Frequently Asked Questions
Is it free?
Yes. No signup required.
Is my file safe?
Yes — your PDF is processed entirely in your browser and never uploaded.
Is the redaction permanent?
Yes. Pages with redactions are rasterized into images with the sensitive text physically destroyed — it can't be recovered by selecting, copying, or inspecting the PDF.
How do I choose what to redact?
Enter search terms (comma-separated) — for example, a person's name, a phone number, or an email address. Every occurrence of each term on every page is found and blacked out.
Does it work on scanned PDFs?
No. Redaction searches for real text in the PDF. Scanned PDFs contain images, not text — run OCR first to add a text layer.
What happens to pages without redactions?
They keep their original text layer — fully selectable and searchable. Only pages where redactions were applied become image-based.
