Slack is a chat application that empowers teams to communicate in real-time and collaborate across departments. It’s a great place to share files and work on projects that come with tight deadlines. Colleagues can easily upload and download files and attachments from within a Slack channel. But it’s important to know Slack’s file size limitations to make sure your team shares efficiently. Here’s a breakdown of the sizes that matter for 2021.

Why file size matters

When teammates are busy collaborating on a campaign launch they need to know their files are going to be received. If you’re not aware of your size limitations, then the chances are you’ll stall projects or delay campaigns, which can lead to deadlines being missed and a decrease in productivity. A clear understanding of file size is critical to the continued fluidity of a project, and to keep teams in sync.

File size limits

Uploading a file into a Slack channel or direct message is easy. You can attach audio, video, screenshots and PDFs and send them to colleagues or groups in an instant. If a file capacity is reached older files are archived within Slack and the user is sent a notification. You can upgrade packages to unarchive older documents. This is beneficial if you want to retrace steps on a given project.

Slack file size limits:

  • Free:            5GB entire workplace
  • Standard:   10GB per member
  • Plus:            20GB per member
  • Enterprise: 1TB per member

Single upload file size limit

The single file size upload limit is 1GB. However, with hundreds of Slack integrations, an alternative option for users is to provide access to Google Drive or a digital asset management solution via a chat channel or direct message. This means if a file is too large to be uploaded to Slack, it can instead be stored and accessed in another location that has larger upload and download capabilities.

Consider the options available to your organization and choose a file size limit that makes space for communicative features that are readily available to your entire team.
