Add files to Slack

To help you collaborate, add files to Slack and share them with your teammates. Uploaded files are stored, searchable and shareable across your workspace. 🗃

How files work in Slack

  • You can add files to your messages in channels and direct messages.
  • You can share files across your workspace or externally.
  • You can comment on files by using threads.
  • Audio and video files play in-line within your workspace, wherever shared.

Note: Files added to Slack may not exceed 1 GB in size. Please note that images cannot be edited from Slack.

To add files to Slack, choose one from your computer or from your preferred file management app.
