A fully client-side PDF redaction tool — no uploads, no server, no data leaves your browser.

🔗 Live Demo

• 📄 Open any PDF — drag & drop or click to upload
• ✏️ Draw redaction boxes — click and drag to mark sensitive areas with black rectangles
• 📑 Multi-page support — redactions are tracked independently per page
• 🔍 Zoom controls — zoom in for precision on small text
• 🗂️ Redaction list — sidebar tracks all boxes; remove any with one click or right-click
• 💾 Export — downloads a real redacted PDF with black fills permanently burned in using pdf-lib

1. Open the app and upload a PDF
2. Switch to Redact mode (default)
3. Click and drag on the document to draw black redaction boxes
4. Navigate pages and add more redactions as needed
5. Click Export Redacted PDF to download the final file

All processing happens entirely in your browser. No data is sent to any server.
