What image size should I use for virtual backgrounds?

1920×1080 pixels (16:9 aspect ratio) works across all major platforms — Zoom, Teams, Google Meet, Webex and Slack. This matches standard HD resolution and ensures your background looks crisp.

Why does my background look mirrored or flipped?

All video platforms mirror your self-view (like a mirror) so your movements feel natural. This means logos and text appear backwards to YOU, but other participants always see your background correctly. Only Zoom and Webex let you disable mirroring in settings.

Do I need a green screen?

No. All modern video conferencing apps use AI-powered background removal that works without a green screen. Good lighting and a contrasting background improve quality. A green screen only helps on older hardware or in poor lighting.

Which file formats are supported?

JPG and PNG work on every platform. Some apps (Zoom, Webex) also support GIF. Video backgrounds (MP4/MOV) are supported by Zoom and Webex but use more system resources.

Can I use virtual backgrounds on mobile?

Yes — Zoom, Teams, Google Meet and Webex all support virtual backgrounds on iOS and Android. Slack currently only supports backgrounds on desktop. Mobile backgrounds can usually be set during an active call.

Why is my virtual background not working?

Common causes: outdated app version, hardware acceleration disabled (Google Meet), insufficient CPU/GPU, or admin restrictions. Check our platform-specific troubleshooting guide for detailed fixes.

All platforms mirror your own preview. "Mirror toggle" means you can turn that off in settings. Others always see your background the right way round.

Why does my background look flipped?

Video apps mirror your own preview, like a mirror, so your movements feel natural. This means any text, logos, or directional elements on your virtual background will appear backwards to you.

The good news: other participants always see your background the correct way around. Your logo, company name, and text all display perfectly for everyone else on the call.

✅ Can disable mirroring

Zoom and Webex both have a mirror setting under Video, so you can see yourself as others see you.

⚠️ No toggle available

Teams, Google Meet and Slack mirror your own preview with no option to change it. Don't flip your image, or it will look wrong to everyone else.

Why use virtual backgrounds?

The same room from anywhere

Kitchen, spare room or hotel: people see the same background on every call.

Your name in the frame

Your home stays private

You decide what people see behind you.

Nothing to buy or hang

It's an image. Your video app does the rest, no green screen needed on most computers.
