Photo Editor Two Photos

Two image inputs (Image A and Image B) feed a deterministic pipeline that outputs alignment, comparison, and composition results. The tool supports JPEG, PNG, and WEBP, with size checks and auto-scaling to a consistent working resolution. Outputs include side-by-side previews, a pixel-difference map, and an exportable montage. It is designed for photographers, retouchers, QA reviewers, and creative teams who need quick visual verification, change-tracking between versions, or creative composites without external software.

Conceptually, inputs are normalized to a common color space and dimensions. The system estimates an offset to align the images, then computes per-pixel differences to generate a map that highlights meaningful changes. Users can control tolerance to ignore minor fluctuations. Blending modes and montage layouts enable integrated composites, while crop and resize options ensure both sources fit a chosen frame.

The tool's value lies in speed, privacy, and consistency: processing happens in-browser, avoiding server round-trips; outputs are exportable at standard formats; it supports a range of use cases from QA checks to creative editing. Audience includes professional photographers and design teams; unique differentiators include built-in alignment, robust difference highlighting, and diverse export options in a single workflow, plus explicit input validation and error handling.
