KDE Mover-Sizer review
A free, portable Windows utility for mouse-based window movement, resizing, and snapping.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
KDE Mover-Sizer is a portable Windows utility for people who want to move and resize windows with the mouse without aiming for title bars or resize borders. Alt + left-click dragging moves a window, while Alt + right-click dragging resizes it from inside the window. It also supports snapping to desktop edges, constrained movement, resizing from screen edges, and working with windows behind other windows. Its focused controls suit solo users and small teams who want straightforward window positioning rather than a broader desktop-layout system.
The tool is free, and the published offering includes downloadable Windows executables. It runs without an installer or registry changes, making portability part of its appeal. Multiple monitors are supported, though the product description does not specify a display limit. The listed controls cover common manual adjustments, but the feature set is narrower than a layout manager: there are no listed layout presets, app rules, window groups, or virtual desktops. Choose it for direct mouse-based movement and resizing; look elsewhere if saved arrangements or automated window behavior are central to your workflow.
KDE Mover-Sizer is built with AutoHotkey, and the product page links to source code. The documented Windows versions are dated, so buyers who need explicit compatibility information for a current Windows setup should review that before relying on it. There are no listed paid tiers to weigh against these capabilities. Overall, it is a fit for Windows users who value a small portable utility and simple controls, but not for people seeking a configurable layout manager or documented application-specific rules.
