Screener

Screener is a feather-light software application that enhances the functionality of the Printscreen key. It lets you preview snapshots before saving them to file, crop them, and quickly send them via email as file attachments.

As long as you have .NET Framework installed on the PC, you don't need to set up anything else. This means that you can save the program files to a custom location on the disk and just click it executable to launch Screener. Another possibility is to keep it stored on a USB flash drive to directly run it on any PC with minimum effort. Plus, unlike most installers, it doesn't modify Windows registry settings.

An important aspect worth mentioning is that Screener doesn't prompt any type of window at launch. However, it brings up a small configuration panel when triggering the Printscreen key.

You can preview the screenhot, edit its height and width, optionally preserve its aspect ratio, crop any part of the picture and save it as a PNG file, as well as send it as an email attachment by specifying the sender and receiver addresses, cc, bcc, subject, and message text.

The snapshot can be saved anywhere on the disk by indicating an output directory, file name and format (PNG, JPG, BMP, TIF, GIF). Aside from the fact that you can open the image in the default photo editor, there are no other noteworthy options.

The software tool worked smoothly in our tests, without triggering the OS to hang, crash or prompt error messages. Unsurprisingly, it left a small footprint on system resources consumption, running on low CPU and RAM.

Although it's not as feature-rich as other snapshot grabbing utilities, Screener offers a simple solution to previewing and cropping screenshots taken with Printscreen, emailing them, and saving them with a preferred file extension.
