Redact PDF

Permanently cover sensitive information and rebuild a sanitized document.

Redaction is permanent

Paperuna does not place cosmetic boxes over recoverable content. It renders sanitized page images into a new PDF and removes common metadata. Keep the original document separately if you may need the unredacted information later.

Private browser processing

Your file stays on this device. Paperuna never uploads, stores or inspects its contents.

Redact PDF questions

Are redactions permanent?

Applied redactions are flattened into rebuilt page images rather than placed over the original content. Always review the final file before sharing it.

Does Paperuna store redacted text?

Yes. Processing runs locally in your browser. Paperuna does not upload, retain or inspect your document content.
