Photo Editor JS

The tool provides a client-side photo editing workflow powered by JavaScript. It exposes a set of non-destructive operations such as crop, resize, rotate, exposure, contrast, saturation, and applying filters. All processing happens in the browser using Canvas APIs, with optional WebGL acceleration where available, ensuring user data never leaves the device.
Input handling: accepts image files (JPEG, PNG, WEBP) or data URLs, and returns edited results as data URLs or Blobs. Changes are staged in a history stack for undo/redo. Validation enforces file size and mime-type constraints, preventing unsupported inputs from failing silently.
Audience and differentiators: designed for developers embedding image editing into apps, designers prototyping assets, and educators teaching image processing. Distinguishing factors include fully client-side operation, a small modular API, non-destructive editing, and straightforward export options.
Core features and use cases: crop, resize, rotate, exposure, white balance, contrast, saturation, and a library of non-destructive filters. Use cases include generating social media assets, in-app image editing, and rapid asset previews.
