Lightshot

Lightshot is a screen capture utility developed for Mac. This program comes as an alternative to hitting the Command+Shift+4 keys to take snapshots of certain desktop areas.

The difference is that the app provides you with screenshot editing options.

This application might come in handy if you need to capture your screen activity and add annotations to the resulted snapshot. You can add text content and geometrical shapes to your screenshot.

Another great aspect is that you can share the snapshots directly from the app's main window. You can send the screenshots via email to a co-worker or post them on your Facebook account page.

The one thing that bothers me is that the program supports only one output format: PNG. Still, this file format is very popular and is supported by almost any image editor for Mac.

Other than that, not much more can be said about this utility. It does exactly what's being said on its homepage, without slowing down your Mac in the process.

In conclusion, you should definitely give this application a try if the aforementioned disadvantage isn't important to you. Lightshot is easy-to-use, offers you many image editing options, and comes without a price.
