Discover collaborative file and document sharing
Bring your files and the conversations surrounding them together in Slack. It's like show and tell, but at work.
Deliver documents from anywhere
Files, documents, photos, and videos can be shared from your computer, device or cloud storage service of choice, all without switching tabs or windows.
Collaborate on large files
Sometimes big files have pieces and parts that span across different software or departments. Discuss the bigger picture and finesse the final product together with in-line file and document sharing.
File sharing, meet channels
In Slack, files and conversations flow in organized, searchable spaces called channels. Channels make it easier to share files and the context around them with the right people — and find those files later on.
Integrated file sharing
From drag-and-drop to quickly adding documents from services like Google Drive, sharing files is as much a part of Slack as typing and sending messages.
