Redacted pages are flattened to an image and the content under each box is permanently removed — it can't be copied or recovered. Text on those pages is no longer selectable.
Permanently redact sensitive information from a PDF — names, numbers, anything — directly in your browser. PDF Bunker removes the content under each box rather than just covering it, and your file is never uploaded.
How it works
- 1Drop your PDF into the upload area, or click to browse for it.
- 2Draw black boxes over any text or images you want removed.
- 3Review your redactions and undo or clear any you need to change.
- 4Click Apply redaction to download a PDF with that content permanently gone.
Frequently asked questions
Is the redacted content actually removed?
Yes. The content beneath each box is stripped from the file, not just visually hidden, so it can't be copied or recovered from the output.
Are my files uploaded to redact them?
No. Redaction runs entirely in your browser. Your PDF never leaves your device.
Does it work offline?
Yes — once the page has loaded, you can redact with your internet disconnected.
Do I need an account?
No. Anonymous users get up to 5 operations per day; a free account gives unlimited basic operations.
