Photo Merge Tool

This tool provides a back-end workflow to merge two source photos into a single composite image. It accepts two image inputs and returns one output file without altering the originals. Users include photographers, designers, and content creators who need quick, repeatable composites for social media, portfolios, or editorial layouts. Supported modes include overlay, side-by-side, and diagonal blends, with adjustable overlap and blend options to tailor the result to the scene.
Conceptually, the tool standardizes inputs to a common color space, computes an appropriate canvas, and positions each image according to the chosen method. It applies pixel-level blending, supports opacity adjustments, and can crop the result to the requested output dimensions. When you select a mode like overlay with 40% overlap and multiply blending, the system preserves details from both photos while producing a cohesive look.
Common use cases include creating doubles-exposure style imagery, aligning two related scenes for comparisons, or generating thumbnails that combine subject and context. It is designed for efficiency and reproducibility in production pipelines, enabling batch-friendly naming and consistent output formats for publishing across platforms.
Unique value comes from explicit control over alignment, blend mode, and output format, plus robust handling of varying input sizes. The tool emphasizes non-destructive processing, clear validation, and predictable results, making it suitable for designers, marketing teams, and freelance editors who need reliable composites without manual retouching.
