File upload limits

Section titled “File upload limits”

The Zulip Cloud Standard and Zulip Cloud Plus plans include 5 GB of file storage per user. Each uploaded file can be up to 1 GB.

The Zulip Cloud Free plan includes a total of 5 GB of file storage. Each uploaded file can be up to 10 MB.

In organizations on a self-hosted server, server administrators can configure the maximum size for uploaded files via the MAX_FILE_UPLOAD_SIZE server setting. Setting it to 0 disables file uploads, and hides the UI for uploading files from the web and desktop apps.
