How to hide sensitive parts of an image

If you’re sharing screenshots, documents, or photos, you might need to hide personal details. Email addresses, ID numbers, names — things you don’t want online.

Pixit is a Mac app that makes this easy. You load an image, draw boxes over the sensitive parts, and either pixelate them or cover them with black.

Steps:

  1. Open Pixit and load your image.
  2. Drag to create one or more boxes over the areas to hide.
  3. Pick either pixelation or black box.
  4. Adjust or move the boxes as needed.
  5. Export your image securely.

It’s better than using Preview or generic tools. You get full control and instant results.
