Redact Sensitive Information in a PDF
Free & private · no signup · no watermarks · files deleted in 1 hour
Need to permanently remove sensitive information from a PDF before sharing it? Our Redact PDF tool blacks out specified text and regions so the content is irretrievably removed — not merely covered with a rectangle that can be deleted in a PDF editor. Specify the text to redact or draw over regions to black out, and the tool permanently removes the underlying content from the file structure itself, not just from the visible layer.
This is critical for legal document production (removing privileged information before disclosure), publishing redacted government records, protecting personal data before sharing internally, and complying with GDPR or HIPAA requirements that mandate the removal of personally identifiable information. Always verify the redacted output in a PDF reader before distribution.
Key features: Permanent content removal — not just a cover • Text and region-based redaction • Compliant with data protection best practices • Supports PDFs up to 100MB • 256-bit SSL • Files deleted within 1 hour • No registration

Frequently Asked Questions About Redact PDF
Everything you need to know about our Redact PDF tool
Yes, completely free. Our Redact PDF tool has no hidden costs, no watermarks, and no registration requirement. You can process as many files as you need, each up to 100MB, at no charge. We believe professional PDF tools should be accessible to everyone — students, freelancers, and businesses alike.
Your files are fully protected. All uploads and downloads use 256-bit SSL/TLS encryption during transfer. Processing happens on our isolated Hetzner server infrastructure in Germany — your file is never shared, analysed for commercial purposes, or stored longer than necessary. Every uploaded and processed file is automatically and permanently deleted within one hour of processing.
Supported file types: This tool accepts PDF files up to 100MB each. For files larger than 100MB, use our Compress PDF tool first.
Portable Document Format
Yes — works on any device. The interface is fully responsive and tested on desktop, tablet, and mobile. Touch-friendly upload areas, drag-and-drop support on desktop, and mobile-optimised buttons mean you get the same experience whether you are on a MacBook, an iPad, or an Android phone. No app download is ever required — open your browser and go.
Yes — the redacted content is permanently and irreversibly removed from the file. Unlike placing a black rectangle on top of text (which can be deleted to reveal the original), our redaction tool removes the underlying characters, images, or objects from the PDF data structure entirely. The output file contains no trace of the redacted content. Always open the output in a PDF reader and verify the redaction before distributing the document.
