There are a bunch of Chrome extensions that do this, but to capture the Slack app, I recommend using CleanShot X on the Mac or SnagIt! on Windows.īoth of these allow you to select a window to be captured, let you scroll all the way down the windows, and then save that giant constructed graphic as a PNG, JPEG, or PDF. To accomplish this, you'll want to use software that can capture a scrolling page. This approach takes a screenshot of the entire message thread, even if you have to scroll for page after page. Save archive using scrolling screenshot software The only downside of this approach is that the final saved archive won't look exactly like it does in Slack.
