Compress Video for Slack
Slack caps single-file uploads at 1GB, but big files eat your workspace's shared storage and upload slowly on office Wi-Fi. Compressing first keeps storage lean and uploads quick — and the file never leaves your device.

Slack upload limits and storage
Slack's per-file limit is 1GB, but every upload counts against your workspace's total storage quota (5GB on the free plan). A handful of raw screen recordings can fill that fast, so compressing before you share keeps the workspace usable.
Frequently asked questions
- What is Slack's file upload limit?
- 1GB per file regardless of plan, but free workspaces share a 5GB total storage cap across all files. Compressing videos before upload stretches that shared quota much further.
- Why are my Slack uploads slow?
- Upload time is bound by file size and your connection's upload speed (usually far slower than download). A 300MB clip compressed to 40MB uploads roughly 7× faster.
