ShareX is a free software to take screenshots on Windows.

Capturing the Windows screen is rather simple; there are plenty of programs to perform this task, and even Windows brings a rudimentary tool for making screenshots. Pressing the "Prt Scr," we get a desktop screenshot. This tool is good, but normally we need more to make screenshots easily, quickly, and efficiently.

ShareX is an ideal solution for screen captures since it allows full screen captures, only a window or selected region. In addition to the basic characteristics that we have just mentioned, this program has several features that make it very handy, for example:

• Screen capture of a particular monitor. If we have multiple monitors, we can select which of their capture.
• Screenshots with the corner rounded, ellipse, triangle, polygon-shaped, or diamond.
• Screenshot with the shape, thanks to the Free Hand selector.

Another important feature is the ability to record what is happening on the screen and create video files or animated gifs. This option is very good since we can record a video of our full desktop or a part by pressing a key combination.

Once we have made the screenshot, we can edit it: crop, rotate, resize, add borders, etc. We can also tweak the settings such as brightness, black and white, saturation, the scale of greys, etc. We can even apply more than one dozen of filters.

We can easily add text annotations, draw geometric figures, draw arrows or lines, and add a watermark. So we can avoid opening an image editor software to perform these simple tasks.

When the screenshot is taken, we can save it to the hard drive, copy it to the Clipboard, print it, or upload it to the Internet.

At the time of uploading the screenshots to the Internet, we have a multitude of image servers to upload, such as imgur.com, flickr.com, imageshack.us, photobucket.com, and more.

We can also upload them to file servers such as Google Drive, RapidShare, mega.co.nz, dropbox.com, and more.

We can even upload screenshots automatically to Twitter.

Once we've uploaded images to the Internet, this software allows us to use shortening URL services such as tinyurl.com, bit.ly, goo.gl, and more.

All these features make ShareX full-featured software, which covers the vast majority of needs when we want to make screenshots. Despite the impressive features, the software is free, and the source code is available to study or modify.
