By no means a replacement for hard core users of SnagIt, Screenpresso is a good, lightweight screen capture tool.

What I like about it:

• No installation required, so you can run it directly from your USB thumb drive (although, you can install it, if you prefer).
• It has the usual tools that are handy for tech writers (arrows, bubble text boxes, callout numbering, blurring, image shaddows, and torn edge effects).
• It has extra features, like automatic image resizing (to a fixed width, height, percentage, or maximum size) and automatic border effects.
• It is free.

It is not perfect and is not feature rich. For example, I did find it had some strangeness when editing text in text boxes and bubbles. Also, you cannot edit saved images using the free version.

Its place in a tech writer’s toolbox could be on their USB thumb drive as a good alternative when they are away from their own computer.
