Redact PDF sensitive information with a visual preview

PDFLuma Redact PDF lets you permanently remove sensitive text, names, numbers, addresses, signatures, images, and confidential information before sharing a PDF. The tool is designed for quick desktop and mobile redaction with a visual preview and clear download flow.

The visual redact preview helps you see the redaction area before processing. You can drag or resize the redaction box and adjust sensitive information using black or white redaction colors. This makes it easier to redact the exact area you want instead of guessing values blindly.

Redacting a PDF permanently removes selected sensitive content from the output file. It helps protect private information before sharing documents with clients, coworkers, schools, government offices, or online services.
