Permanently redact and blackout sensitive PDF text

Frequently Asked Questions
How secure is Redact PDF?
Redact PDF uses industry-standard algorithms processed entirely within your browser. No passwords, encryption keys, or file data are transmitted over the internet, making it as secure as offline desktop software.
Is it safe to use Redact PDF with confidential documents?
Absolutely. Redact PDF processes everything locally inside your web browser using JavaScript and WebAssembly. Your files are never uploaded to any external server. Sensitive documents, contracts, and personal files remain completely private on your device.
Is Redact PDF really free? Are there hidden limits?
Yes, Redact PDF is 100% free with no hidden costs. There are no file size limits, no daily usage caps, no watermarks on your output, and no account registration required. Use it as many times as you need.
Does redaction really delete the text?
Yes. Unlike simply placing a black box over text (which can be removed), PDFtoPixel’s redaction permanently destroys the underlying text data from the PDF structure. The content cannot be recovered.
