PDF Redact
Select areas on a page preview or enter coordinates, then rebuild the PDF from masked page images locally. Original content objects, metadata, and attachments are not copied. The output is image-only and loses searchable text, vectors, accessibility tags, and existing digital signatures. Review every selection before exporting.
