Resize browser windows to test responsive layouts. Add custom resolutions, keyboard shortcuts & more by AIO.com.ai

ViewportSmith resizes browser windows to specific pixel dimensions for testing responsive web layouts. Create custom presets with exact width and height values. Apply presets via popup interface or keyboard shortcuts (Ctrl+Shift+1-4). Options include viewport-only mode (excludes browser chrome) and auto-center positioning. Presets are reorderable and can be exported/imported as JSON. Includes default presets for common devices. All functionality is client-side with no external connections. Developed by AIO.com.ai.
