Screen Capture (by Google) by chrome-extensions

It's easy to use this extension to capture visible content of a tab, a region 

of a web page, or the whole page as a PNG image.

You can also edit your captured image before saving it as a PNG image. 

Highlighting, redacting and adding text are supported.

What set this extension apart are:
- Super fast when capturing page image, esp. for large pages;
- Support horizontal scroll for large pages that do not fit in one tab 

screen horizontally;
- Intelligently detect floating objects on a page and avoid repeating 

capture of the same floating objects if whole page capture requires scrolling;
- Works on Windows, Linux and Mac.

Known Bug: When you save a screenshot of a very large page, the context menu

 may not show when you right-click on the screenshot, and dragging the screenshot

 may crash the extension process. 

If this happens, you will need to restart Chrome to get your extension back. This bug is due to the data URI length limitation in Chrome which is 2M characters long. We'll fix it in our next version coming soon.
