Better Screen Sharing on Mac
ZoneShare improves how you share your screen on macOS — especially on large and ultrawide displays. Share precise regions, keep your desktop private, and present like a professional.
Most Screen Sharing on Mac Could Be Better
The tools built into macOS and meeting apps weren't designed for large or ultrawide displays.
Screen sharing is a staple of remote work, teaching, and presentations. But on large and ultrawide monitors, the standard approach — share the whole screen — produces content that's too small, too wide, or too exposed.
The alternative, sharing a single window, breaks down when a window is wider than a standard frame or when you need to switch between several apps during one presentation.
- Squished content. Wide desktops get compressed to fit the meeting frame, making everything harder to read.
- Privacy exposure. The whole screen is visible, including messages, tabs, and files you'd rather keep private.
- No focus. Viewers can't tell what matters in a busy, cluttered desktop.
- Limited tools. Standard sharing offers no way to draw, spotlight, or keep a consistent aspect ratio.
ZoneShare: Professional Screen Sharing for Mac
A full set of tools for sharing exactly what you want, the way you want it.
- Selective screen sharing. Mirror only the region you choose into a window or virtual camera — never your whole desktop.
- Custom screen regions. Position and size your region precisely, with presets for the most common ratios.
- Aspect ratios. Keep your share at 16:9 or another standard ratio so it always fits the meeting frame.
- Presentation tools. Spotlight, blur, draw, zoom, and time your presentation — right inside the shared region.
- Keyboard shortcuts. Switch between regions and tools instantly with customizable hotkeys.
ZoneShare brings together everything you need for professional screen sharing on macOS: selective regions, standard aspect ratios, drawing and annotation, spotlight, blur, keystroke visualization, and a built-in timer.
