Thumbizy is a free, instant website thumbnail generator that can help you to take snapshots of any website. You only need to give the URL of the web site and select the thumbnail size. Thumbizy will instantly provide you a screenshot of your given web site. You can store locally, and then insert it into a web page, a PowerPoint presentation, a word processing document, or anyplace else you might need it.
Thumbizy is purely cloud-based. All the software is stored in a web server someplace; there is no software to install on your local computer. Thumbizy works well with Windows, Macintosh, and Linux systems.
To use Thumbizy, you go to the web site at http://www.thumbizy.com, enter the URL of the site you wish to capture, select from a few options, and then click on GO. A short time later the thumbnail appears on your screen. You can then right-click on the image and follow the menus to save the image to your hard drive.
Simple and free. That's what I like about useful programs.
I have included a few samples of thumbnail images I created with Thumbizy.
