How to compress a video for Slack
| # | Step | What happens |
|---|---|---|
| 01 | Drop your clip | MP4, MOV, or WebM — decoded in the browser. |
| 02 | Pick Medium | Tuned for Slack's 1 GB (workspace-dependent) ceiling. Switch levels if you need more quality. |
| 03 | Check size and send | Download the MP4 and upload in Slack. |
Slack stops oversized sends at about 1 GB (workspace-dependent). Slack free/pro file limits are high (often up to 1 GB); practical caps are network and patience. Use Medium compression in your browser — no upload.
Slack limits
Size: 1 GB (workspace-dependent). Slack free/pro file limits are high (often up to 1 GB); practical caps are network and patience.
For channel demos, 1080p Medium is a good default; use Strong on mobile networks.
Slack’s file cap is high on many plans, but slow Wi‑Fi and mobile still punish huge uploads.
How this preset helps
Default recommendation: Medium. You can still pick Strong, Medium, or Light and preview before download.
Compression runs on your device. Exports stay clean — no watermark.

Tips
Huge uploads clog threads — compress so people can scrub the clip.
Prefer MP4 H.264 for the widest Slack client support.
Trim the take before you compress.
Questions

No. The compressor runs in your browser for this job.
Use /compress-video for Strong / Medium / Light without a platform default.
More than a video compressor
Under the cap, the clip can still be better. Convert the container, stabilize, reframe for social or add captions. Studio exports at the size you set after the edit, not before it.
