Sensitive data

Secrets on screen? Hide them.

The best screenshot of your product often has something in it that shouldn’t be shared: a live API key, a customer’s email, a face. SnapStudio finds them and covers the ones you choose, before the image goes anywhere.

Every “after” on this page is SnapStudio’s own output, not retouched.

What it looks for

  • API keys and tokens
  • Email addresses
  • Card numbers and IBANs
  • Phone numbers and IP addresses
  • Links with tokens in them, and home-folder paths
  • Faces

How to use it

  • Select the image layer in the Layers panel.
  • Choose Edit → Redact…. The screenshot is scanned on your Mac.
  • Every finding is listed and selected; untick anything you want to keep.
  • Pick a style and click Redact.

Choose the right cover

A solid block is permanent. Pixelation and blur look softer, but blurred or pixelated text can sometimes be reconstructed, and SnapStudio warns you when you pick them for text.
