How to blur your background in Microsoft Teams

Blurring hides what’s behind you so people focus on you. Most issues happen when Effects and avatars is missing, camera permission isn’t granted, or org policy blocks effects. The fix: turn your camera on, open Effects and avatars, choose Blur, and apply.

Before you start

• Use the desktop or web app for full controls; mobile supports blur, too.
• Good lighting improves edge detection around your face and shoulders.
• Custom images may be blocked by policy. If you want more than blur, see change your background in Teams.
• Presenting content? Review how to share your screen in Teams.

1) Blur before you join (desktop/web)

1. Select Join on your meeting.
2. On the pre-join screen, select Effects and avatars (sometimes labeled Background filters).
3. Choose Blur.
4. Select Join now.

Visual cue: On the pre-join preview, look for the wand/star icon or Effects and avatars link near your camera toggle.

2) Blur during a meeting (desktop/web)

1. On the meeting toolbar, select More (⋯) → Effects and avatars.
2. Choose Blur → Apply.

Pro tip: Select Reset in the same panel to return to your real background.

3) Blur on mobile (iPhone/Android)

1. Join the meeting.
2. Tap More (⋯) → Background effects.
3. Choose Blur → Done/Apply.

Why use it: Quick privacy when joining from busy places.

4) Beyond blur: replace the background

If you want a branded look or a different scene, use built-ins or upload an image with this guide: change your background in Microsoft Teams.

Troubleshooting

• No Effects and avatars option: Update Teams or switch to the new Teams client; your org may restrict effects.
• Blur is greyed out or low quality: Improve lighting, face the camera, and close heavy apps; integrated GPUs can struggle.
• macOS shows black video: Grant Screen Recording/Camera permissions to Teams in System Settings → Privacy & Security and restart Teams.
• Effect resets each call: Re-apply blur, then sign out/in to refresh cached settings.
• Can’t upload images: That’s policy. Use Blur or built-ins, or ask IT.

FAQs

Does blur affect screen sharing?
No—blur only changes your camera feed. Your shared screen is unaffected.

Will participants still see movement behind me?
Blur obscures details but strong motion may show as shapes. For full privacy, switch to a replaced background.

Does blur stay on for future meetings?
Often yes, but it can reset. Check Effects and avatars on join.
