Mac Window Snapper

Snap and tile macOS windows from your Stream Deck. Position the frontmost window to halves, thirds, quarters, or arrange multiple windows — all with a single key press. Works on all apps including Adobe and Electron. Dynamic key icons show the snap layout at a glance.

Universal compatibility — works on all macOS applications including Adobe Illustrator, Photoshop, InDesign, and Electron-based apps. Not limited to apps with Apple's Window > Move & Resize menu.

Dynamic key icons — each Stream Deck key displays a visual diagram of the snap layout. The icon updates automatically when you change the position in settings.

Halves — snap to the Left, Right, Top, or Bottom half of the screen.

Thirds — snap to Left 1/3, Right 1/3, Left 2/3, Right 2/3, or Center 1/3. Ideal for ultrawide displays where you want a large workspace alongside a narrower reference panel.

Quarters — snap to Top Left, Top Right, Bottom Left, or Bottom Right quarter.

Fill & Center — fill the entire usable desktop, or center the window at a comfortable reading size.

Arrange — position two windows from the frontmost app at once: Left & Right, Right & Left, Top & Bottom, Bottom & Top, or all four Quarters.

Return to Previous Size — restores the window to its original position and size from before the last snap. The plugin remembers each app's previous frame automatically.

Window controls — Zoom, Minimize, and Close the frontmost window.

Smart screen detection — automatically accounts for the menu bar and Dock, regardless of their position or size. Works correctly on MacBooks with the notch, ultrawide monitors, and multi-display setups.

Now works on multi screen layouts.
