Redact PDF — Permanently Black Out Sensitive Content, Free
Cover sensitive text, numbers, or images in a PDF with permanent black boxes. Unlike simply drawing a shape over content, redacted pages are flattened into images so nothing underneath can be recovered. Everything happens locally in your browser using JavaScript — your PDF is never uploaded to a server, so it's safe to use for private, sensitive, or confidential documents.

Frequently asked questions
Is this real redaction, or just a black box on top of the text?
Pages with redaction boxes are rasterized into flattened images, so the original text and images underneath are destroyed — not just visually hidden — making the redaction permanent.
Will pages without redaction boxes stay text-selectable?
Yes — only pages where you draw a redaction box are converted to images. Untouched pages keep their original vector content and selectable text.
Can I redact multiple areas on the same page?
Yes — draw as many boxes as you need on each page before moving to the next.
