1. Using Markup Editor

The iPhone’s Markup editor offers a native tool to hide sensitive information in photos. While it’s not a proper blur feature, it gets the job done as you will see in the following steps. This method comes in handy to censor text from photos.

  1. Launch the Apple Photos app and open the picture in which you want to hide text or face.
  2. Tap on the Edit button at the top and press the Pen icon to open the Markup editor.
  3. Tap on the (+) icon at the bottom of the Markup editor and select the Square box from the menu.
  4. Tap on the Square/circle shape icon at the bottom and choose the filled-in square present on the left side.
  5. Drag the box over the area that you want to hide. Also, you can adjust the size of the box using the blue circles.
  6. You can also change the color of the filled-in box to black or grey from the colors at the bottom.
  7. Finally, tap on Done at the top right corner followed by Done again on the screen that shows up to save the edited image. Please note that the edited image will replace the original image after saving. Pro Tip: To remove the filled-in square from your image, open the image and tap on the Edit button. Press Revert to undo any edits.
