About Redact PDF

Redact PDF permanently blacks out sensitive text and regions in the browser before you share a file. Manual boxes, phrase search, and helper patterns for emails or IDs keep PII off the wire — unlike cloud redactors that require uploading the unredacted original.

How to use Redact PDF

1Open Redact PDF and drop the document you own.
2Draw boxes, search phrases, or apply detection helpers for common PII patterns.
3Review every page — redaction is irreversible once burned in.
4Download the redacted PDF. The unredacted original never left your device.

Frequently asked questions

Is redaction just a black rectangle overlay?

Proper redaction removes or obscures underlying content so it cannot be copied from under a highlight. Always verify by selecting text in a reader after download.

Can I undo redaction?

No. Keep a private unredacted copy offline. Treat the download as permanent.

Does redaction work on scanned PDFs?

Yes for visual regions. Text search needs a text layer — run Searchable PDF or PDF OCR first if the scan has none.

Is this legal for court filings?

Toolncy cannot give legal advice. Confirm your jurisdiction’s rules and verify the output in a desktop PDF reader.

Why redact locally?

Uploading unredacted PII to a third-party SaaS creates a retention and breach surface. Local redaction avoids that hop.
