File sharing, meet channels

In Slack, files and conversations flow in organised searchable spaces called channels. Channels make it easier to share files and the context around them with the right people – and to find those files later on.

Integrated file sharing

From drag-and-drop to quickly adding documents from services such as Google Drive, sharing files is as much a part of Slack as typing and sending messages.

How to add files to Slack

Your files: Safe and secure

We take security seriously, including the safety and privacy of your files. When you share files in private channels or messages, only the included people can see those files or find them in search.

Different devices, same documents

As you go about your day and switch from one device to the next, Slack automatically and instantly syncs the messages, files and documents in all your channels and messages.

Yes. We take security seriously, including the safety and privacy of your files. Data at rest in Slack’s production network is encrypted using FIPS 140-2 compliant encryption standards, which applies to all types of data at rest within Slack’s systems, including relational databases, file stores and database backups. For data in transit, Slack supports the latest recommended secure cipher suites to encrypt all traffic in transit, including use of TLS 1.2 protocols, AES-256 encryption and SHA-2 signatures, whenever supported by the clients. To ensure that only the right people and approved devices can access your company’s information in Slack, we also offer many built-in security features, such as single sign-on. You can learn more about these on our security page.

Please note: Slack does not control the nature of the data submitted to Slack workspaces. The customer is the controller of customer data, which is defined as messages, files or other content submitted through Services accounts. Please see Slack’s privacy policy section on ‘Information we collect and receive’ for more details on the data elements, including any personal data elements defined as ‘other information’ that are controlled by Slack.

Great question! The amount of storage space varies according to your subscription and how many people are in your company’s Slack workspace. Here’s how it works:

• Free subscription: 5 GB total for the entire workspace
• Pro subscription: 10 GB per member
• Business+ subscription: 20 GB per member
• Enterprise Grid subscription: 1 TB (1,000 GB) per member

All PDFs, documents, images, screenshots and audio and video files uploaded to a channel or direct message count towards the file storage limit.
