On the Mac, how can I take a screen shot of a window that includes the parts that are off-screen and need scrolling to become visible?

The built-in Grab application can capture individual windows, but it only includes the parts that are on-screen at the moment.

Clarification: By "off-screen" I mean parts that are in the window, but are not visible, because the window has scrollbars. I do not mean parts of the window that are simply off-screen because of how the window is positioned (of course, I want those, too).

LittleSnapper will capture whole web pages, but not capture scrolled window contents in applications such as Finder.

Here is a website with 6 Screenshot Utilities (including LittleSnapper and some others that will capture whole pages).

There is a utility specifically for Finder listings called Print Window.

Update (2021)

The ability to do this is now built into Safari and is super easy.

File > Export as PDF... will get you what you want in most cases.

See this answer for more details on how to snapshot a whole page or a sub-section of the page.

There are also similar capabilities in Firefox & Chrome.

Original answer

Snagit is the only software I've found for macOS that can do this for scrolling application windows as well as web pages.

There is a pretty good tutorial available, but basically when you are making a capture you can click on the vertical scrolling button and it will manually scroll the application window and piece together all the shots to make a comprehensive shot - very helpful!

Hope this helps!

While Little Snapper can take a picture of an entire web page, and Layers can capture every element on your screen (including stuff that’s hidden by other windows in front of it)—it’s unlikely you will find an application that can take a picture of the off-screen regions of a window.

The reason is that many applications don’t draw the off-screen portion until it’s needed. Often that part of the display isn’t even rendered until you scroll it into view. So a theoretical “whole window” snapper would capture a lot of blank or undefined areas.

If you just want to grab the output of a webpage as an image you can check out webkit2png or Paprazzi, a GUI similar in practice to webkit2png. Little Snapper does this as well.

In any browser, you can do File->Print. Then select PDF->Save as PDF...

Most web site don't have a special "Print" CSS, so the result in the PDF is reasonably equivalent to what you see.

To convert to another format, open the PDF with and Save as... you can select in a good list of formats (TIFF, PNG, GIF, JPEG...)

For Firefox centric usage, Awesome Screenshot addon is pretty great and allows snapping entire web pages.

This drove me crazy for a while, too. But here's how you do it in little snapper:

  1. Open the web page you want to capture
  2. Click on the LittleSnapper icon in the toolbar at the top of your screen (looks like a camera lens)
  3. Select 'Open current website in LittleSnapper' (I've found that this works for Safari but not Chrome)
  4. In the LittleSnapper browser, click the camera icon to 'Snap the current webpage'
