Android Overlay Editor

This tool solves the problem of visualizing how an overlay image interacts with a base photo, with a focus on Android-style graphics. It is used by mobile UI designers, game developers, photographers, and content creators who need to preview asset interactions and explain layering concepts. It supports use cases ranging from app screen mockups to marketing visuals and educational tutorials, offering repeatable results without installing desktop software.
Conceptually, compositing places the overlay on the base and applies transforms—translate, scale, rotate—and an opacity value. A selected blend mode then combines color channels to achieve the final look. The system validates inputs, clamps numerical values, and enforces the specified canvas size. It preserves alpha when formats support transparency, enabling clean overlays on non-opaque bases.
Key features include explicit inputs for position, size, and rotation; adjustable opacity; multiple blend modes; and straightforward export options. These capabilities enable designers and developers to iterate quickly, enforce brand-consistent visuals, and create reference assets for specs, demos, and tutorials.
Unique value lies in providing a lightweight, scriptable workflow that pairs precise control with a minimal feature set. Users can craft Android-like overlays for screen previews, prototype assets, and teach layering concepts in design curricula, all within a browser without installing heavy software.
