Now you can hide sensitive parts of an image using similar technology. Think of it as a digital marking pen that works on the Mac’s screen. The utility is called Black Out. Duh. What it does is black out parts of an image you don’t want others to see.
We’ve all seen or read about redacted documents the government releases to media or the public. Such blackouts help to obscure some information while allowing related information to remain visible. Black Out does that with any image you want to share but contains something you do not want others to see.
It’s like Magic Marker on the Mac’s screen.
This app can be useful when you want to post a screenshot or photo on the web that contains some information you don’t want to be revealed. Maybe you want to share a screenshot of a Slack conversation on Twitter but hide some private information.
Images also contain metadata that can reveal even more information than the image itself. Black Out fixes that, too.
It also removes all metadata, like when and where a photo was captured.
Easy peasy privacy secrecy. How does Black Out work?
- Drag and drop an image onto the window
- Drag and drop an image on the Dock icon
- Click the Open button and choose an image
- Right-click an image in Finder and choose Black Out in the “Open With” menu
From there just click and drag to create black boxes that cover over the sections of the image that need to be hidden. The black boxes can be moved around; typical Mac drag and drop. Click Export and the redacted image gets saved wherever you choose.
Black Out doesn’t cost much but doesn’t have a try-before-you-buy option. Otherwise, good for the money, and much faster than Photoshop.
