Black box redaction tool

Black out text in image online

Cover text with a solid black box before sharing an image. This is the classic redaction style and the best choice when the hidden information must not remain readable.

What to black out

How to black out text

  1. Open your image in Redacted.
  2. Drag over the text you want to hide.
  3. Choose the black box mask.
  4. Adjust the box so it covers the full line.
  5. Download the redacted image.

Why black boxes are stronger than blur

Blur and pixelation can be acceptable for casual screenshots, but a solid cover removes the visible detail from the exported image. Use black boxes for sensitive text, IDs, legal details, or financial information.
