How to: Redact PDF
- Select your PDF.
- Enter words to redact and/or draw boxes on the preview.
- Click Start and download the redacted PDF.
Drawing a black box over text in many editors leaves the text underneath – anyone can copy it out. True redaction removes it. Fileopia rebuilds every redacted page so the hidden content is gone, and because it runs locally, the sensitive document never leaves your device.
Common uses
- Hide account numbers, ID numbers and signatures before sharing.
- Remove personal data from documents released under privacy or freedom-of-information requests.
- Black out client names in case studies or court filings.
Tips for best results
- Search for a word to redact every occurrence at once, then add boxes for images or signatures.
- Check the result by trying to select and copy text in the redacted areas.
- Also run Remove PDF Metadata – author names and titles can reveal information.

- Check the network: open your browser’s developer tools (F12 → Network) while processing; you will see no file upload requests.
- Nothing to delete: close the tab and the data is gone – there is no server copy, no retention period and no account.
