Format posts on your desktop

Posts are a way to create, edit and share fully-formatted documents in Slack. Text formatting in posts is designed for simplicity, with just the right options to organize your thoughts.

Posts can only be created and edited from Slack on your desktop, but you can view them from our mobile apps.

Tip: Learn all about composing your first post, and sharing it with your workspace, in Composing a post.


Paragraph formatting

When you're writing or editing a post, hover over any text to view the paragraph menu located on the left. 

Click the ¶ icon for styling options, then pick from the following: 

  • the       icons for headings and subheadings
  • the   icon for numbered lists
  • the   icon for bulleted lists
  • the   icon for checklists
  • the  icon for code blocks

Tip: Checklists are a great way to create and share to-do lists. Click the ¶ icon by your first item, then select the  checklist icon. Press Enter to add more items or a checkbox to mark an item as done.


Selection formatting

Selecting a range of text in your post displays a style menu.

Here, you can choose from bold, italics, underline, strikethrough, and code snippet styles. You can also create linked text.


Keyboard shortcuts

Posts support keyboard shortcuts for quick and easy formatting. We’ve included familiar, standard keyboard shortcuts for ease — like using Cmd B (Mac) or Ctrl B (Windows) to bold text you’ve selected.

For a list of keyboard shortcuts, press Cmd / (Mac) or Ctrl / (Windows) or just click the  More menu icon at top right and select Keyboard shortcuts. Here you can see a list of Markdown-style formatting shortcuts if you prefer, too.

Hint: A few formatting options are only available via keyboard shortcuts, so it's worth checking them out!


Add images to your post

It's not possible to attach or upload an image to a post. However, if you want to include an image, just paste a link to the image in an empty paragraph. If it's a public or shared file, the image will expand automatically. 

Link previews

Just like links in your Slack messages, you can expand links in your posts to show a preview of the content. It’s as simple as clicking the link you want to expand, then clicking the   eye icon.


Note: Some websites don’t offer content previews; in these cases, clicking the eye icon will not expand the link.
