Image Overlay Editor

The tool enables non-destructive composition by keeping base and overlay assets as separate layers. Users upload a base image and an overlay asset, then position, scale, rotate, and adjust opacity. Blending modes provide creative variants such as normal, multiply, screen, and overlay. The system previews changes in real time, enabling precise alignment with guides and snapping options. This design supports designers who need quick iterations for blog thumbnails, product images, or branded visuals without desktop software.
Conceptually, the tool treats each input as a separate layer in a compositing pipeline. The base layer is rendered first, then the overlay layer is composited using alpha blending. Coordinates and scaling are stored as metadata, allowing non-destructive edits later. When exporting, the tool renders a final raster at the requested size and color space (default sRGB) and saves as PNG or JPEG. The value proposition includes instant previews, repeatable layouts, and low-friction asset reuse across projects.
Who benefits: designers, marketers, social media teams, and developers producing on-brand visuals. Unique differentiators include a lightweight, browser-based workflow that preserves original assets, supports multiple overlays, and includes alignment guides without requiring complex software. Use cases span watermarking, mockups, event graphics, and catalog imagery. In-scope exports and non-destructive edits enable rapid experimentation, versioning, and stakeholder reviews.
