Photo Editor Superimpose

This tool enables deterministic overlay composition by accepting a base image and a second overlay image. It exposes inputs for anchor position (x, y), scale, opacity, and a selection of blend modes to achieve effects from subtle watermarking to bold composites.
The core workflow applies the overlay atop the base using linear RGB color space, preserves transparency, and outputs a final PNG suitable for web or print. Advanced options include rotation, masking, and edge feathering to smooth transitions between layers. The design targets designers, marketing teams, and photographers who need repeatable results and strict control over how the overlay integrates with the base image.
Conceptually, the tool treats each input as a layer in a single composition. The overlay is transformed according to the chosen position and scale, then blended with the base using the selected mode and opacity. The resulting image preserves the base resolution and keeps pixel data intact for downstream editing or direct export. The unique value lies in providing a compact, predictable overlay workflow with a clear set of controls, enabling rapid iteration across many assets while maintaining visual consistency.
