How to Share Only Part of Your Screen on Mac
Sometimes you don't need to share the whole screen. ZoneShare lets you define a precise screen region on your Mac and share only that — in Zoom, Microsoft Teams, Google Meet, and any presentation app.
Why Share the Whole Screen at All?
Full-screen sharing is a habit, not a requirement — and it comes with real downsides.
Sharing your entire Mac screen exposes everything: notifications, chat windows, personal files, and apps you'd rather keep to yourself. It also forces viewers to scan a busy desktop instead of focusing on the content you're talking about.
For presentations, teaching, and remote work, showing the whole screen rarely helps anyone. What matters is the one window, slide, or document you're working with — and that's exactly what should be on screen.
- Privacy benefits. Keep messages, files, and notifications out of the call while still sharing your work.
- Focused viewers. When only the relevant content is visible, people follow along instead of getting distracted.
- Readable content. A narrow, well-framed region stays large and crisp in every meeting app.
- A professional look. No more fumbling with windows or apologizing for a cluttered desktop.
Share Exactly the Region You Choose
ZoneShare gives you precise control over what your audience sees.
- Define your region. Drag a frame over any part of your screen, or enter exact pixel values for pixel-perfect positioning.
- Lock an aspect ratio. Keep the region at 16:9 or another ratio so it always fits the meeting frame.
- Mirror it cleanly. The region appears in the Zone Share window or the Zone Share Camera — never your whole desktop.
ZoneShare is built for exactly this: selecting a precise area of a Mac screen and sharing only that area. The rest of your display simply doesn't exist to the meeting.
You can reposition the region anytime, save positions for quick access, and even blur sensitive apps that happen to appear inside it. To keep your share at a standard size, see our guide to sharing a 16:9 area, or go deeper with better screen sharing on Mac.

Present data, documents, or designs without showing messages, tabs, or anything you'd rather keep private.

Demonstrate one tool or concept clearly while keeping the rest of your setup out of the frame.
