Add files to Slack

When you work with your team in Slack, you can add files to your workspace to discuss them with colleagues. Files are searchable and shareable across Slack, making it easier for everyone to find the information they need and work together.

Note: Uploading and sharing files may be restricted for Slack Connect conversations, and certain file types can't be added at all. If you can't add files to these conversations, find an owner or admin and ask for help.

Add files from your device

  1. Drag and drop up to 10 files into the message field in Slack, or click the   paper clip icon next to the message field and choose files to add.
  2. Include a message about the file(s) if you'd like. If you're adding an image, you can also include a description.
  3. Send the message.

Note: Files added to Slack may not exceed 1GB in size.

Add files from file management apps

Once a file management app has been added to your workspace, you can add files to Slack by clicking the   paper clip icon to the right of the message field, then selecting your preferred app. Files added from an app will not be stored in Slack, but will still be searchable and shareable across your workspace. Visit an article below to get started:

  1. Open a channel or direct message (DM).
  2. Tap the message field. Tap the  file icon to add a file already shared in Slack or tap the  image icon to select up to 10 photos.
  3. Add a message about your file(s) if you'd like.
  4. Tap the   paper plane icon to send.

Tip: Looking to add a file to a thread? Tap the thread to open it, then tap the blue arrow to find the   file and  image icons.

Slack will include a preview of a file as part of your message. If you share an image, the preview will only display inline if it's smaller than 11,000 pixels on the longest side, or less than 45 million pixels total. Microsoft Office files that are larger than 50 MB will not display a preview.

Note: Files you add to Slack will be scanned for viruses and other malware, and won't be uploaded if any are detected.
