Free tool like Snagit which can capture scrolling Window?

The free version of FastStone Capture will capture a scrolling web page. Works best with IE but also works with FF (it scrolls the window very slowly) and kinda works with Chrome (page is OK but it messes up the the scroll bars).

There's also PicPick (use the 'Capture Window Control' command) which works with IE and Firefox though won't scroll in Chrome.

I use the free ScreenGrab add-on for Firefox, which can capture a selection of a page, the visible portion, or the whole page past the scroll area. In addition, it can also copy to clipboard, or save as JPG or PNG. I've been using it for over a year now with no ill effects -- it's great.

If you're using Firefox, then FireShot might be what you're looking for.

Web Screen Capture - a free stand-alone web site and web page screenshot and thumbnail utility.

I use Aviary.com, an online application that can do screen captures (region, visible, or whole pages) and online editing. They have an online video about their service here.

Their free service does what you need. It's all online, no software to install. I use a Firefox extension which makes it really easy to use.

Two of the best I have found (that have scrolling web page capture) for Windows and both freeware are:

• Greenshot

• SnapCrab

SnapCrab was reviewed by DownloadCrew and their verdict was that it was a serious competitor to Snagit.

With the option to download from there as well.

If you want a portable tool with all the features that you can carry around on a USB stick I would highly recommend PicPick Portable.
