Slack says your video is too big? Don’t worry. The maximum video upload size is 1GB per file. If your video exceeds 1 GB, try the video compressors mentioned in this article to bypass Slack video size limit.

What Is Slack?

Slack is a communication and collaboration platform for businesses and teams. Team members can share files, including videos, audio, documents, and images, on this platform. It supports multiple video formats, including AVI, MKV, WMV, MP4, 3GP, M4V, MPG, and MPEG.

Slack also supports voice and video calls, improving communication efficiency among team members. Furthermore, Slack integrates with thousands of applications, including Google Drive, Trello, and GitHub. This reduces the need for users to switch between different platforms, significantly improving work efficiency.

Maximum Video Upload Size of Slack

Slack allows you to upload videos to channels or private messages. You can upload up to 10 files at a time, including videos, documents, and images. However, the maximum video size on Slack is 1GB. In addition, different pricing plans offer different file storage capabilities. The free version offers only 5GB of total file storage, the Pro version offers 10GB, and the Business version offers 20GB.

How to Bypass Slack Video Size Limit?

Videos larger than 1GB cannot be uploaded to Slack. This will affect your workflow. Therefore, check your video file size before uploading. Videos larger than 1GB need to be compressed beforehand.
