How redaction works
The tool paints opaque black regions on rendered pages, then builds a fresh image-only PDF. It does not copy original text streams, metadata, annotations, attachments or signatures. It checks for extractable PDF text in the result. Always inspect the downloadable PDF visually before sharing.
Limitations
Identifier suggestions are incomplete, especially for scans or fragmented text. Review all pages and use manual rectangles. The PDF becomes image-only and loses accessibility and searchability. Password-protected PDFs are not supported.
