Obfuscate – utility to censor private information

In Operation

Obfuscate has a delightfully simple user interface. Here’s what you see starting the app.

Drop an Image

We can either drop an image into the above window, or click the Open button. The software supports PNG, JPEG and BMP formats.

There are two tools to conceal an image. The most secure is the fill tool which lets you draw a black box around sensitive information. The other tool is a blur function; the program warns that this tool is not secure and should not be used when sharing sensitive information in a public arena.

Other features of the program include:

  • Undo/redo.
  • Zoom function.
  • Keyboard shortcuts.


Obfuscate is a simple tool but needs to be used sensibly. The blur function can easily be reversed. At least the program gives an adequate warning in this regard. It would be much better if blurring wasn’t based on the area itself but with a pattern unrelated to the information in the image.

The other option to use a solid colour to hide sections of an image can easily be achieved by any half-decent image editor such as the sublime GIMP. But Obfuscate may be all you need.
