PDF Redact
Permanently remove sensitive content from PDFs.
How to use this tool
Steps
- Add a PDF and wait for page previews to render.
- Open each page that contains sensitive material and draw boxes slightly beyond the full area that must disappear.
- Review every page at useful zoom, including headers, footers, repeated identifiers, attachments, comments, and pages with no marks.
- Export the rebuilt PDF, reopen it in another viewer, search for the removed text, and inspect document properties before sharing.
Supported formats
- Input: a PDF that PDF.js can render.
- Marks: rectangular regions drawn on page previews.
- Output: a PDF with rasterized marked pages and copied unmarked pages.
Things to know
- The tool cannot know whether every sensitive area was marked.
- Unmarked pages are copied, so their original text, metadata, annotations, and attachments require separate review.
- Rasterized pages lose selectable text and may be less accessible.
- A visual black box can hide too little if the mark does not cover the complete glyph or surrounding context.
