Gemini Transparent PNG App Creation

Apps

Create a minimalist web-based tool that generates transparent PNG files with user-specified aspect ratios, featuring a clean interface with input fields for width and height dimensions (or common preset ratios like 16:9, 4:3, 1:1), a preview area showing the transparent canvas dimensions, and a prominent download button that instantly generates and downloads a fully transparent PNG file matching the specified aspect ratio. The tool should include intuitive controls with real-time dimension feedback, support for both custom pixel dimensions and standard aspect ratio presets, validate inputs to prevent errors, display a visual representation of the canvas size without actual content, and provide immediate file download functionality with appropriately named files (e.g., "transparent_1920x1080.png") while maintaining a responsive, accessible design that works across all modern browsers and devices.
