Thumbnail Grabber is a tool to create thumbnail screenshots of web pages in JPEG or PNG format.
You can choose web page size (width and height) and thumbnail image size (in percent of the web page size).
Thumbnail Grabber can batch process URLs and domains from a text file.
Free for private, non-commercial use.
