Protect your privacy before posting images. Blur or pixelate phone numbers, addresses, faces, and ID numbers. Processed locally in your browser — your data never leaves your device.

Before sharing a screenshot in a group or on social media, always check for sensitive information: phone numbers, WeChat IDs, addresses, ID numbers, faces. Blurring sensitive info is the essential step to protect yourself.

What needs to be blurred

  • Contact info: phone, WeChat, QQ numbers
  • Identity: ID numbers, names, addresses
  • Biometrics: faces, fingerprints
  • Account info: bank cards, verification codes
  • Private content: sensitive conversations

Two ways to blur

Pixelation (mosaic): pixelates the area, cannot be restored — the safest option.

Blur: applies Gaussian blur to hide details. Pixelation is more thorough; use it when in doubt.

Blur sensitive info with PixelForge

Open the PixelForge Mosaic tool — processed entirely in your browser, no upload. This matters for privacy.

Step 1: Upload the screenshot or photo. Step 2: Drag to select sensitive areas (phone, face, etc.), multiple areas supported. Step 3: Apply pixelation or blur, adjust strength, export.

Tips

  1. When in doubt, blur it — better safe than sorry
  2. Pixelation beats blur for thoroughness
  3. Check the background for hidden info
  4. Use a local-processing tool — no upload means truly safe
