Yes. The tool blacks out the selected information completely and removes it so it cannot be recovered or extracted from the document afterward. This irreversible removal is what makes it safe for sharing sensitive files.

No. Only the redacted areas are removed. All visible content retains its original high quality, formatting, and resolution. You can download the redacted PDF immediately, ready to share with the sensitive parts permanently erased.

Yes. Every step happens locally in your browser, so your document is never uploaded to any server. Sensitive legal, medical, or financial files stay entirely on your device throughout the redaction process, ensuring complete privacy.
