How to Blur Background in Microsoft Teams: Guide [2026]
Step-by-step guide to blur background in Microsoft Teams during live calls on Windows, Mac, and mobile, choose Standard vs Portrait blur, troubleshoot when background effects are grayed out, and blur Teams meeting recordings afterward with BGBlur.
How to blur background in Teams is one of the most common Microsoft 365 setup searches — and it makes sense. Enterprise calls often happen from home offices, co-working spaces, or open-plan floors where whiteboards, monitors, and family members can drift into frame.
Microsoft Teams includes built-in background blur (Standard and Portrait) plus custom virtual backgrounds — no green screen on supported devices. But blur can be missing on Linux, blocked on VDI, or absent from a recording you saved for training or social clips. This guide covers live Teams background blur on Windows, Mac, iPhone, and Android; how to set blur as default; troubleshooting; and post-meeting cleanup with BGBlur when native blur was not enough.
| Question | Answer |
|---|---|
| Blur before joining? | Pre-join → Effects and avatars → Blur → Standard or Portrait |
| Blur during a call? | More actions → Video effects and settings → Apply |
| Blur on phone? | Pre-join or More actions → Change background / Background effects → Blur |
| Blur a saved recording? | Download MP4 → BGBlur background blur |
How to Blur Your Background in Microsoft Teams (Live Meeting)
Teams uses AI segmentation to separate you from the room — the same class of technology behind phone portrait mode. According to Microsoft's guide to changing your background in Teams meetings, you can blur or replace your background before you join or while you are already in the call.
Microsoft notes that blurring does not guarantee sensitive information stays hidden — readable text on walls or screens may still be legible if lighting and angle align badly. For external publishing, treat live blur as a convenience layer and run recordings through a second privacy pass when needed.
Before a Meeting (Windows or Mac Desktop)
- Open the Microsoft Teams desktop app (recommended over browser for full background support).
- Join or start a meeting to reach the pre-join screen.
- Select Effects and avatars.
- Click the dropdown arrow next to Blur.
- Choose Standard blur (soft background) or Portrait blur (stronger depth effect).
- Optionally select Preview, then join the meeting.
Your choice persists for future meetings until you select None or upload a custom background.
During a Meeting (Desktop)
- In meeting controls, select More actions (⋯).
- Choose Video effects and settings.
- Select Video effects.
- Under Blur, pick Standard blur or Portrait blur.
- Select Preview if available, then Apply.
Shortcut path: Click the dropdown arrow next to the Camera icon during the call to open background options directly — same blur choices, faster access mid-meeting.
On iPhone or Android
- Open the Teams mobile app and tap Join on a meeting.
- On the pre-join screen, tap Change background or Background effects.
- Select Blur, then Join now.
During the call: Tap More actions → Change background or Background effects → Blur → Done.
If Background effects is grayed out, turn on your camera first — Teams disables effects when video is off.
Standard Blur vs Portrait Blur in Teams
| Effect | Look | Best for |
|---|---|---|
| Standard blur | Even soft blur across the background | Daily standups, internal calls, neutral professionalism |
| Portrait blur | Stronger subject isolation, heavier bokeh | Client calls, webinars, presentations where you want a “shot on a pro camera” feel |
| Custom image | Replaces room with JPG/PNG/BMP | Branded backdrops, office stock photos |
| None | Real room visible | When blur artifacts appear on hair or glasses |
Neither blur mode redacts faces of other people walking behind you or text on monitors with perfect reliability. For compliance-sensitive shares, pair live blur with post-production tools — see workplace meeting recording privacy for why recordings leak more often than live video suggests.
How to Set Teams Background Blur as Default
Teams remembers your last background effect:
- Open Effects and avatars on the pre-join screen.
- Select Standard blur or Portrait blur.
- Join the meeting — no extra save step.
Every subsequent meeting on that device uses the same background until you change it. IT admins can disable custom backgrounds org-wide via Microsoft 365 policies; if blur vanishes for your entire company, contact your administrator before assuming a hardware issue.

When Teams Background Blur Is Not Available
| Issue | Fix |
|---|---|
| Linux Teams client | Background blur is not supported on Linux — use Windows/Mac or post-blur recordings |
| VDI / virtual desktop | Optimized VDI blocks background effects — use physical device or BGBlur on exports |
| Camera off | Enable camera in pre-join; grayed-out effects usually mean video is disabled |
| Outdated app | Profile → Check for updates in Teams desktop |
| CPU / AVX requirements | Older PCs may lack AVX2 support — try custom static background image instead |
| Browser-only join | Install Teams desktop app for full Video effects menu |
If live blur is impossible, upload a static Teams background image (office, brand color wall) via Add new, or blur the recording after the fact — next section.
How to Blur Background on a Teams Recording (After the Meeting)
Teams blur applies to the live feed only. When you record to OneDrive, SharePoint, or Microsoft Stream, the file reflects whatever was on camera — including an unblurred room, gallery tiles, and shared screens.
Use post-production blur when you:
- Forgot to enable Teams background blur before recording
- Need to publish a clip to LinkedIn, YouTube, or an LMS
- Must redact participant faces in gallery layout
- Want stronger blur than Standard/Portrait provided on hair, glass, or busy backgrounds
Step 1: Download the Teams Recording
- Meeting chat → recording link → download
- OneDrive / SharePoint →
Recordingsfolder - Microsoft Stream (if your org uses it) → export MP4
Step 2: Upload to BGBlur
- Go to bgblur.com or the AI video background blur tool.
- Upload the Teams MP4.
- Choose background blur for the speaker’s room, or add face blur for multi-participant layouts.
For screen recordings that capture Slack, Teams chat, or email alongside video, see blur chat messages in screen recordings — a common gap when training videos show sensitive threads.
Step 3: Preview and Export
BGBlur tracks motion across frames so blur follows you if you shift in chair. Preview, download the redacted MP4, and share. Files are deleted from BGBlur servers within 24 hours.

Teams Blur vs Virtual Background vs BGBlur
| Method | When to use | Limitation |
|---|---|---|
| Teams Standard / Portrait blur | Every live call on supported devices | No Linux; weak on some VDI; not editable after record |
| Teams custom background | Hide room completely with branded image | Edge artifacts; lighting-dependent |
| BGBlur (post-production) | Training libraries, marketing clips, compliance exports | Requires upload after the meeting |
Best practice for hybrid teams:
- Enable Portrait or Standard blur in Teams before external calls — per Microsoft's official background guide.
- Before posting any saved recording publicly, run it through BGBlur if faces, whiteboards, or room details need redaction.
- Combine background blur with AI face blur when gallery view or B-roll captures coworkers without consent.
Tips for Better Teams Background Blur Quality
- Light your face — backlight from a window confuses segmentation and creates halo edges.
- Avoid busy patterns behind you — blur handles plain walls best.
- Use Preview on desktop before Apply on important client calls.
- Check hair and glasses — Portrait blur can flicker on fine detail; Standard blur is sometimes smoother.
- Do not rely on blur for secrets — Microsoft explicitly warns blur may not hide sensitive information; redact recordings before wider distribution.

Conclusion
How to blur background in Teams splits into two moments: during the Microsoft Teams call and after you save the recording. Live, use Effects and avatars or Video effects and settings to apply Standard blur or Portrait blur on desktop and mobile. After the call, upload the MP4 to BGBlur when native Teams background blur was off, insufficient, or when the recording needs face redaction before it goes outside your org.
