Redact PDF
This tool draws opaque black rectangles over selected areas of your PDF pages so the covered content is no longer visible. Important: this is visual masking, not secure redaction — the original text still exists in the PDF's content stream and can be copied or extracted by anyone with a PDF reader. Do not rely on it to remove truly sensitive information; render pages as images instead if you need genuine content removal.

Frequently Asked Questions
Is this redaction secure?
No. The tool only draws black rectangles over the content. The underlying text remains in the PDF and can be copied, selected, or extracted with standard PDF tools.
How do I genuinely remove sensitive content from a PDF?
Render each page as an image (for example by taking screenshots or exporting to images) before sharing. This destroys the selectable text layer so nothing can be extracted.
When is this tool useful?
It is useful for purely visual purposes, such as preparing mockups or hiding content in printed copies where the digital file will not be distributed.
