There are several easy ways to upload a file from your computer:

  • Copy and paste images directly into the message box. 
  • Upload a file by clicking the  plus icon next to the message box.
To upload a file:
  1. Once you select a file to upload, Slack will prompt you to decide where you'll share it.

Note: Hold the Shift key while dropping or pasting the file and it will upload instantly, bypassing the option to add a title and comment.

File storage

Every Slack team is provided with storage for uploaded files. The amount of space varies by plan:

  • Free plan — 5GB total for the entire team
  • Standard plan — 10GB per team member
  • Plus plan — 20GB per team member
  • Slack Enterprise Grid — 1TB (1,000 GB) per member

Slack will let you know once you've reached your storage limit. For more space, you can delete older files or consider upgrading your plan.

Tip: Audio and video files, including .mp3, .mp4, .wav, and .mov will play inline on Slack's desktop app — no need to download the file!
