CamTuner for Slack Huddles
Show up framed and centered in Slack Huddles. CamTuner adjusts your webcam in the browser before Slack sees it — free and on-device.
Huddles are casual, but a bad camera angle is still the first thing people see in an async-friendly workplace. Slack's small video bubbles amplify the classic webcam problem: too much room, not enough you.
CamTuner works with Slack in the browser at app.slack.com. Set your framing in the extension and every huddle shows the cropped, centered version of your feed.
Does CamTuner work with Slack Huddles?
Slack Huddles in the browser
Works. CamTuner adjusts the camera stream inside the browser before the platform receives it.
Slack Huddles desktop app
The desktop app captures your camera outside the browser, so CamTuner can't adjust it. CamTuner works when Slack runs in Chrome at app.slack.com. The Slack desktop app loads its own environment, so huddles started there are not tuned.
Set it up in under a minute
Add CamTuner to Chrome
Install from the Chrome Web Store and grant camera access.
Set your framing
Choose your aspect ratio, zoom and alignment in the CamTuner popup.
Start the huddle from app.slack.com
Open your workspace in Chrome (rather than the desktop app), start or join the huddle, and keep your normal camera selected.
Recommended framing for Slack Huddles
Slack Huddles reads best with a 16:9 frame. See exactly how to set it up in our crop to 16:9 guide, or try your framing live in the demo on the homepage.
Good to know
Bookmark the web workspace
If your team lives in the desktop app, keep app.slack.com open in a Chrome tab for huddles so your framing is always applied.
Screen shares are untouched
CamTuner only adjusts camera streams, so your window and screen shares behave exactly as before.
Slack Huddles + CamTuner FAQ
Does CamTuner work in the Slack desktop app?
No. Huddles started in the Slack desktop app use a camera path outside the browser. Run Slack in Chrome at app.slack.com and CamTuner's framing applies automatically.
Do huddle participants see the adjusted video?
Yes. The stream is tuned before Slack receives it, so everyone in the huddle sees the framed version.
Can I use different framing for different workspaces?
CamTuner keeps one global framing by default, with per-site overrides supported — so you can tune Slack differently from other tools if you want.
