What is Snagit?

TechSmith has a history of producing well-designed reliable software with plenty of features, and Snagit is no exception. It's very lightweight and unobtrusive during the recording phase, and finishes the capture process with a capable image editor that can be learned in just a few minutes. Once you're satisfied with the final product, you can share your creations online to a wide range of services from an FTP to Youtube with just a few clicks. The only issue that I have with Snagit is the price point. It's a bit expensive for a screen capture program, and a similar price point can often get you a decent video editor that includes a screen capture feature.

You already have a basic free screenshot tool. For Windows, you can take a screenshot by pressing the Alt + PrtScn keys; For Macs, it's Shift + Command + 4. If that's all what you what, you don't need to use Snagit at all. But if you are a blogger, journalist, or tutorial maker who has the needs to blur sensitive information, add fancy callouts, capture video of your PC/Mac screen, Snagit is the perfect choice. We highly recommend it.
