How do I permanently remove sensitive text from a PDF?

Upload your PDF to lnpdf, select the text or areas you want to redact, and the tool will permanently black them out. The underlying data is completely removed, not just covered.

Is drawing a black box over text the same as redacting?

No. Drawing a box only covers text visually — it can still be copied or extracted. lnpdf's redaction tool permanently deletes the underlying text data so it cannot be recovered.

Can I search for specific words to redact across the entire PDF?

Yes. lnpdf offers a search-and-redact feature that finds every occurrence of a word or phrase across all pages and redacts them in one step.
