Add files to Slack

When it's time to collaborate on a file, you can upload it to your workspace by adding it to your message. Uploaded files are stored, searchable, and can be shared across your workspace. 🗃

How files work in Slack:

  • Add files to messages in channels, direct messages, and threads.
  • Share files in other conversations across the workspace, or externally.
  • Comment on files by starting or replying to a thread.
  • Play audio and video files inline in your workspace.

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