Protect your personal identity before submitting documents online. Easily create UIDAI-compliant Masked Aadhaar cards, redact mobile numbers, black out bank details, and erase confidential text on photos and multi-page PDFs with 100% browser-local privacy.
Permanent Pixel FlatteningUnlike basic highlighter overlays that can be removed in PDF readers, our engine permanently destroys redacted pixel data upon export, rendering it impossible to recover or inspect.
UIDAI Masked Aadhaar StandardEasily comply with Indian regulatory guidelines by masking the first 8 digits of your Aadhaar number (XXXX XXXX) and QR code, leaving only the legal last 4 digits visible for hotel check-ins and KYC.
Select any PDF, JPG, or PNG document, or press Ctrl + V to paste directly from clipboard.
Choose Blur (soft gaussian), Pixelate (mosaic blocks), Blackout (opaque bar), or Whiteout (eraser).
Click and drag boxes across Aadhaar digits, signatures, phone numbers, or QR codes. Adjust blur intensity or pixel size sliders as needed.
Download the permanently flattened PDF, JPG, or PNG, or click Direct Print for instant physical copies.

| Redaction Mode | Visual Appearance | Primary Use Case | Permanent Flattening? | Compliance Standard |
|---|---|---|---|---|
| Blackout (Redaction Bar) | Solid opaque black rectangle | Court filings, Aadhaar numbers, PAN, bank details | 100% Irreversible | Legal & Judicial Redaction Standard |
| Pixelate (Mosaic Tile) | Coarse blocky pixel grid | Faces, QR codes, barcode numbers, stamps | 100% Irreversible | UIDAI Masked Aadhaar Standard |
| Gaussian Blur | Smooth, soft lens defocus | Addresses, background clutter, phone numbers | 100% Irreversible | Privacy & Social Media Sharing |
| Whiteout (Eraser) | Solid white background color | Erasing scanner smudge marks, unwanted pencil notes | 100% Irreversible | Document Cleaning & Reprinting |
Blur applies a soft Gaussian smoothing to obscure details. Pixelate creates a mosaic tile effect. Blackout places an opaque solid black redaction bar over text (ideal for official legal redactions). Whiteout replaces the area with solid white (useful for erasing unwanted marks before printing).
Open your Aadhaar card in the tool, select either Blackout or Pixelate mode, and draw a mask box covering the first 8 digits of the 12-digit Aadhaar number (e.g. XXXX XXXX 1234) and the QR code, leaving only the last 4 digits visible.
No. When you export or download the file, the underlying pixels within the redacted area are permanently destroyed and flattened into the image raster. There are no hidden vector layers or recoverable metadata underneath.
