How it works

Protect sensitive regions in a few steps.

  1. Upload an image.
  2. Draw a rectangle around the sensitive area.
  3. Choose blur or solid redaction and repeat as needed.
  4. Flatten the result and download the cleaned image.
Privacy note

Blur is a visual effect, while redaction uses an opaque replacement to permanently hide sensitive pixels in the generated copy. For highly sensitive data, prefer Redact.
