Frequently Asked Questions About PDF Redaction
Is the redaction really permanent?
Yes. The tool draws a solid, irreversible black or white rectangle over the designated area within the PDF's content stream. For a client-side solution, this ensures the content is visually and functionally blocked, preventing standard copy/paste or search functions from accessing it.
Is it safe to use this tool with sensitive documents?
Yes. This is the safest way to redact a file. Because the tool runs 100% in your browser, your PDF is **never uploaded to any server**. Your private information remains on your computer at all times.
What color can I use for redaction?
The tool currently applies a **black** rectangle for the redaction box, which is the industry standard for permanently obscuring sensitive data.
