Draw Redaction Masks
Use the redact tool to draw black rectangles over sensitive information. Each mask is stored with precise coordinates.
Rasterize & Export
We convert each page to high-quality images with redaction masks permanently applied, then assemble into a new PDF.
🔒 Privacy-First Approach
Guaranteed Content Removal: Our rasterization pipeline ensures that underlying text is completely removed and cannot be recovered. The exported PDF contains only images with redaction masks permanently applied.
No Server Uploads: Everything runs in your browser. Your documents never leave your device.
