Real redaction, not just a black box. The text underneath is permanently destroyed, and nothing is uploaded.
No. The PDF is opened, redacted and verified entirely inside your browser. It never leaves your device, and no server ever sees the document or the text you redact.
A black rectangle drawn over text leaves the text in the file, where anyone can copy it. To destroy it, each page that has redactions is rendered to an image with the black boxes painted in, and that image replaces the page. The hidden text is gone for good. Pages without redactions are copied unchanged and keep their selectable text.
The free version redacts documents of up to 10 pages. Pro removes the page limit. Checking a redacted PDF for hidden text is always free and unlimited.
Yes, with the Draw tool. Scanned pages are already images and have no text layer, so Find & Redact cannot search them. Draw boxes over what you need to remove. The tool does not perform OCR.
