Photo Merge Online

This tool merges two photographs into a single composite image without requiring desktop software. It accepts two image inputs and renders them on a unified canvas, enabling creative overlays or collages for quick content creation. The core workflow focuses on domain-relevant operations rather than UI specifics.\n\nIt supports multiple blend modes (normal, multiply, screen, overlay, darken, lighten) and per-image opacity to control how layers interact. Users can align, resize, or auto-match dimensions, with options for resizing, letterboxing, or cropping to produce a clean final canvas. The processing is designed for non-destructive, on-the-fly composition suitable for web-based workflows, ensuring fast feedback and predictable outputs for social media, marketing, or portfolio work.\n\nBenefits include reduced editing time, predictable export formats (PNG/JPEG), and the ability to experiment with different looks without dedicated software. Use cases cover product comparisons, creative overlays, mood-board visuals, and quick mockups for client reviews. Unique value lies in combining two images with sensible defaults, while still exposing advanced settings for detailed control, without requiring complex tooling.
