Redact PDF permanently blacks out sensitive text or regions, such as social security numbers, account details, or confidential clauses, before sharing a document externally. HR teams removing personal identifiers from records and legal teams preparing court filings for public release both depend on proper redaction rather than a cosmetic highlight that can be reversed. Redaction is applied to the page content locally in your browser, so the unredacted original never leaves your device during the process.
A proper redaction removes the underlying text content from that area rather than just drawing a black box over it, preventing copy-paste recovery.
Yes, you can draw as many redaction boxes as needed across any pages before applying them all together.
No, properly applied redaction removes the underlying text so it cannot be selected or copied from the redacted area.
Once applied and downloaded, the redaction is permanent on that file; keep your original unredacted copy separately if you need to make changes later.
Yes, you can black out any visual area on a scanned page, though there is no separate text layer to remove in that case.
