Frequently Asked Questions

What does PDF redaction mean?

PDF redaction is the process of permanently removing or hiding sensitive information from a PDF document by covering it with solid black boxes. Unlike highlighting or annotating, true redaction ensures the hidden content cannot be recovered, revealed, or searched — it is gone from the file permanently.

Is the redaction truly permanent and secure?

Yes. PDFWorld uses PDF-lib to draw a solid, opaque black rectangle directly into the PDF content stream. This is a content-level redaction — the covered area becomes a permanent part of the page. Unlike CSS overlays or annotation layers, the underlying text in the redacted area is not separately extractable by copy-paste or screen readers.

Is my confidential document safe when I use this tool?

Absolutely. Our PDF Redaction tool runs 100% in your browser using PDF-lib and PDF.js. Your document is never sent to any server, never stored, and never logged. It is ideal for redacting confidential legal contracts, medical records, HR documents, Aadhaar numbers, financial statements, and court filings.

Can I redact multiple pages in one go?

Yes. Navigate between pages using the page controls and draw redaction boxes on each page that requires it. The tool tracks all your redaction boxes across all pages. When you apply redactions, all boxes on all pages are burned into the document in a single download.

How do I redact an Aadhaar card number or PAN number from a PDF?

Simply upload the PDF, zoom in if needed, and drag a redaction box directly over the Aadhaar or PAN number printed on the page. The black box will permanently cover those digits in the downloaded file. This is the safest way to share sensitive ID documents without exposing private identification numbers.

Does redaction work on scanned PDFs?

Yes. Since PDFWorld draws black boxes directly onto the rendered PDF page regardless of whether it contains selectable text or scanned images, redaction works equally well on both text-based PDFs and scanned image PDFs.

Are there any hidden charges or watermarks added to my redacted PDF?

No. PDFWorld is 100% free, with no subscriptions, no watermarks, and no usage limits. You can redact as many documents as you need. We believe privacy tools should be freely accessible to everyone.
