Capture by AppzlrHow to screenshot a long Slack conversation
Open Slack in Chrome and use Capture, a free Chrome extension. Choose Scrolling area, click the messages and press Capture the whole area. It scrolls the conversation and stitches it into one tall image. To capture a thread, click inside the thread instead.
Slack's messages scroll inside the page, not the window, so ordinary full page screenshot tools only capture what's on screen.
Screenshot a long Slack conversation or thread
Open Slack in Chrome
Add Capture from the Chrome Web Store, then open your Slack workspace in Chrome and go to the channel, message or thread.
Load the messages you want
Slack loads older messages as you scroll up. Scroll up until the first message you want is on screen.
Pick the message list
Click the Capture icon in the toolbar to open the side panel. Choose Scrolling area, then click anywhere in the messages, or in the thread.
Press Capture the whole area
Capture scrolls the messages from top to bottom and stitches every shot into one image.
Save or edit it
Click Download to save the capture as a PNG. With Capture Pro, click Edit to crop it, add arrows, boxes or text, or blur private details first.
- Free captures are up to 150 shots long. Capture Pro goes up to 1000.
- Capture Pro adds blur, a highlighter and numbered steps, for screenshots you share at work.
Questions and answers
Can I capture the Slack desktop app?
No. Capture is a Chrome extension, so it captures Slack in Chrome. Open your workspace in the browser to capture it.
Can I capture just a thread?
Yes. Open the thread, choose Scrolling area and click inside the thread instead of the channel. Only that list is captured.
Can I hide names before I share it?
Yes, with Capture Pro ($10/month or $100/year). The editor's blur tool hides names, emails and numbers. The free plan downloads the capture as a PNG, without editing.
