Screenshots

Description

Black Out lets you quickly hide sensitive parts of an image.

This 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.

It also removes all metadata, like when and where a photo was captured.


# Getting Started

Either:
- 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
- Paste in an image from another app or Finder (Click "Paste" in the "Edit" menu or press Command+V)

Then click and drag to create black boxes over the parts of the image you want to hide. You can move a box around by dragging it. When you’re happy with the result, click the Export button to save your new redacted image. You can also copy the redacted image (Click "Copy" in the "Edit" menu or press Command+C) for use in another app, or paste it into a directory in Finder.


# Frequently Asked Questions

‣ Does it support PDF?
You can open a PDF document, but you have to export it as a PNG image. It's almost impossible to reliably export redacted PDFs.

‣ Can you support blurring and pixelation?
Blurring and pixelation are intentionally not supported as they can sometimes be reversed (Search for "blurring sensitive"). The only reliable way to redact something is to put a black box over it.

‣ I can already do this in the Preview app!
You can do this in any graphics app. The point of this app is to make the task super easy to do. Most graphics apps, like Preview, Pixelmator, and Photoshop, preserve metadata, which means you could accidentally leak information like the capture location. Black Out strips out all metadata.

HeySRI ,

Exactly what I needed

This app does exactly what I need, and the developer seems to be committed to making sure it is fully secure (it strips out metadata, and does not support insecure methods like blurring).

Would recommend this app 100%, great work!

Developer Response ,

Note that macOS scales screenshots to half the size when viewing them in Quick Look and the Preview app. When you export the screenshot from Black Out, this "scale" metadata is lost, and you will see the screenshot at full size. This might be what's causing the impression of worse resolution.

Would you be able to email me at sindresorhus@gmail.com with a screenshot of how the yellowish transparency looks like so I can investigate?

Awesome App

Great app. I used to use preview but it was clunky. This is fast and easy! Super helpful. 5 stars!

Very Basic App

This app has a lot of promise but it is too basic to be useful. Want to resize the black bar? Nope. Want to angle it slightly? Nope. Not worth more than .99 cents

Developer Response ,

The simplicity is a feature. It's not technically hard to add support for resizing and rotating, but it's intentionally left out. The app is meant to make it very quick to black out sensitive parts of an image. Adding advanced features which slows down the user goes against that. If you need a lot of control, you might as well use a real image editor. I'll make sure to make the intention of the app and the lack of these features clear in the App Store description.
