About the Redact PDF Tool
Draw a box over anything you want to permanently hide on a PDF page — the black box is drawn directly into the page content, not just a visual overlay, so the original information cannot be recovered from the exported file.
100% Private — Processed in Your Browser
Every file stays on your device. DCPIXEL processes images entirely using the browser's built-in Canvas API and WebAssembly — zero server uploads, zero data collection.
Premium Features & Batch Processing

Frequently Asked Questions
Is the redaction actually permanent?+

Can I redact more than one area per page?+
Yes, draw as many boxes as you need on each page before saving.
Does this work on scanned PDFs?+
Yes — redaction works on any page regardless of whether it contains real text or a scanned image.
