Use a canvas in Slack

When you need to share information that won’t fit in a simple message (such as project plans or meeting notes), create a canvas. A canvas is a surface built into Slack where you can create and share fully formatted content. You can use a canvas in two ways:

  • In a channel or direct message (DM)
  • On its own

A channel or DM canvas

Edit a canvas

To edit a canvas, you'll need Editor access. Anyone with Editor access will be able to apply formatting, mention people and add comments to the canvas.

A channel or DM canvas

The ability to edit a channel or DM canvas is determined by the following:

  • Whether you're a member of the conversation
  • Whether a channel manager has set edit permissions to Anyone who can post in the channel or Channel managers only

If you belong to a channel and can't edit its canvas, ask the channel manager for permission to edit.

Tip: Review our guide on canvas sharing, security and access to learn how to share and assign permissions.


A standalone canvas

If you need to edit a View only canvas, you can request editor access from your desktop using the steps below.

  1. From your desktop, click   View only in the top-right corner of a canvas, then click Request edit access.
  2. Your request will be sent to the canvas’ owner for review, and you’ll be notified once the request is approved.

You can send the canvas owner a reminder of your outstanding request by repeating step 1.

Note: It’s not currently possible to request edit access on mobile.


Apply formatting

You can apply a variety of formatting options to the text in a canvas, such as headers, block quotes and bullet-point lists. You can also insert audio and video into a canvas to have it play inline, and inserting a file or another canvas will include a preview.
