Black out sensitive text or images before sharing a PDF — for real. The redacted area is flattened into the page itself, not just covered with a box, so nothing underneath can be selected or copied out. Runs locally in your browser.
How to use this tool
- 1
Upload your PDF
Click the upload area or drag in the document with sensitive content.
- 2
Jump between pages
Click any page in the thumbnail rail to see it — mark boxes on as many pages as the document needs.
- 3
Draw over what to hide
Drag over each area you want permanently blacked out — draw as many boxes as you need.
- 4
Redact and download
One click redacts every page you marked and downloads the result — nothing is uploaded first.
Why use this tool
Nothing leaves your device
Redaction happens locally in your browser — the document is never uploaded.
Genuinely removed, not just covered
The redacted page is rebuilt as a flattened image, so the underlying text truly can't be recovered — unlike a simple black rectangle placed on top.
Common use cases
Hide an ID or account number
Black out a social security number, account number, or other identifier before sharing.
Prepare a document for legal disclosure
Redact privileged or confidential sections before producing a document.
Share a form without private details
Hide a signature, address, or other personal field before forwarding a form.
Pro tips
- This tool redacts one page at a time — repeat it if you need to redact multiple pages.
- Because the redacted page becomes an image, its text is no longer searchable or selectable — this is intentional for real redaction.
- Double-check the downloaded file before sharing — redaction can't be undone once shared.
