Uses for an online webcam mirror

Check your hair, makeup, or outfit before a video call.

Mirroring vs. flipping

A horizontal flip (left–right) is what creates a mirror image - the reflection you see when looking at a physical mirror. A vertical flip produces an upside-down image. A 180° rotation combines both.

In video conferencing, Zoom mirrors your self-view by default (so you see yourself as in a mirror) but transmits the unmirrored feed to other participants. This is why writing or text visible in your background may appear reversed to you but correct to others.

Zoom, Teams, and Meet self-view note

Each video conferencing platform handles self-view mirroring differently:

Zoom: mirrors self-view by default; can be toggled off in settings.
Google Meet: also mirrors self-view; others see the unmirrored feed.
Microsoft Teams: mirrors self-view; this is the standard behaviour.

This means your own face always looks slightly unfamiliar to you in calls - you are accustomed to seeing the mirrored version (from your bathroom mirror), not how others actually see you.

Fullscreen as a large mirror

Press F11 (Windows/Linux) or enter fullscreen via your browser menu to expand the mirror to fill your entire screen. This works particularly well on desktops and with a phone’s front-facing camera. Some browsers require a user gesture to enter fullscreen; clicking the fullscreen button in the tool handles this automatically.
