Files never leave your browserPermanently remove sensitive content by rasterizing redacted pages.
⚠️ How this redaction works
Any page with a redaction box is fully rasterized (converted to a flattened image) before download — the original text and vector content for that page are not carried over to the output, so there's nothing left to select or extract underneath the black boxes. Pages with no redaction boxes are left as-is (still selectable text), since they weren't marked sensitive.

Frequently asked questions
How does PDF redaction work here?
You draw blackout boxes over sensitive areas, and the tool draws opaque solid black rectangles over those coordinates on the PDF page.
Are redacted documents safe to share?
Yes. For maximum security when redacting highly sensitive documents, printing or flattening the resulting file ensures visual obscuration.
