Redact a PDF — for real, without uploading it
Hide sensitive data with permanent black boxes: search for a word, redact every e-mail address at once, or draw over any passage.
True redaction: the hidden text is removed from the file, not just covered — and the document never leaves your computer.
How to redact a PDF properly
Many tools just draw a black rectangle on top of the text; the text stays in the file and can be copied or the box removed. Here every redacted page is saved again as an image with the redaction burned in, so the hidden text no longer exists in the PDF.
Search for a name and redact every occurrence, use the quick button to redact all e-mail addresses, or draw boxes by hand — which also works on scanned PDFs. Check the pages and download.
Anonymize documents before sharing
Redaction is what you need before publishing a decision, answering a records request, filing exhibits or sharing a contract without exposing third parties’ personal data. The redacted file also leaves out the original metadata, such as author and title.
Frequently asked questions
Can the redaction be removed later?
No. Redacted pages become images with the black box burned in; the text underneath no longer exists in the file.
Does it work on scanned PDFs?
Yes, by drawing the boxes. Automatic search needs selectable text, which scans don’t have.
Are pages without redactions changed?
No. Only redacted pages become images; the rest stay identical, with selectable text.
Is the document uploaded?
No. Searching, redacting and saving all happen in your browser.
