Photo Editor Overlay

The tool provides a web-based workspace to apply overlays to images without desktop software. It accepts a base image via upload or URL and supports multiple overlay types: text blocks, vector shapes, and image-based overlays. Each overlay is a separate layer with independent properties (visibility, opacity, blend mode) and can be reordered. The system validates inputs, preserves transparency, and outputs a final composite in common formats.
Overlay rendering follows a repeatable pipeline: compute a transform for each layer (position, scale, rotation), constrain overlays inside image bounds, and perform alpha-blended compositing in the correct order. Text overlays support font selection, size, color, alignment, and line height; shapes offer color, border radius, stroke, and opacity; image overlays reference uploaded sources. Exports include PNG, JPEG, and WebP with resolution matching the working canvas.
Audience and value: designers, marketing teams, social managers, and ecommerce publishers gain speed and consistency. Unique differentiators include a templates library, non-destructive editing, and the ability to save overlay configurations for future assets. Use cases range from social posts and banners to product images and ads, with scalable workflows from single assets to batch processing.
