Posts let you create, edit and share fully formatted documents directly in Slack. They’re a great way to share and collaborate on long-form content – like project plans or meeting notes.
Note: You can view posts on Slack’s mobile apps, but you’ll need to use Slack on your desktop to create and edit them.
Create a post
From your desktop, click the lightning bolt icon in the bottom left of the message field.
Under Slack, select Create a post.
Enter a title and begin typing. Your post will be saved automatically.
Access your posts
From your desktop, click File browser at the top of your left sidebar. If you don't see this option, click on More to find it.
Click on Filter.
Open the File type drop-down menu, then select Posts.
Share a post
Open your post by clicking on the Edit in new window icon.
Click Share in the top right.
Under Share in, search for a channel or person to share your post with.
To allow shared editing, tick the box next to Let others edit this post.
Click Share to finish.
Copy a link to a post
Open your post by clicking on the Edit in new window icon.
In the top right, click the three dotsicon.
Click Copy link.
Edit a post
Open a post by clicking the Edit in new window icon.
Make your changes. If you didn't create the post, click Edit first.
When you’ve finished, click Finished editing.
Enable shared editing
To let other members to edit your post, you can allow shared editing:
Open your post by clicking on the Edit in new window icon.
Click Share in the top right.
Tick or untick the box next to Let others edit this post.
Click on Share to save.
Only one person can edit a post at a time, so the Edit button will be unavailable when someone else is making changes. Any member can edit a public post, but posts shared in private channels and direct messages can only be edited by members of those conversations.
Format a post
When you're writing or editing a post, you'll see a menu with formatting options appear when you highlight a portion of text.
Add images to a post
Images from Slack
For images that have been shared to your Slack workspace, use the steps below:
From your desktop, hover over the image that you'd like to use.
Click on the three dots icon and choose Copy link to file.
Paste the link in the post. If the image is public and shared, it will automatically expand in your post.
Images from the web
To add a web image, copy the image URL and paste it to your post.
Note: Images will not display in posts if Slack can't detect an image's file extension, or an image URL is added to a list in a post.
