Eliptum Cover Image Optimizer

Eliptum Cover Image Optimizer introduces an asynchronous, sandboxed client-side processing workstation running completely within the user's local browser environment. By manipulating pixels strictly via HTML5 canvas operations, it completely isolates production web servers from standard memory-intensive image handling overhead.

Users can safely load local resources via drag-and-drop mechanics, execute real-time relative crops, target dedicated layout viewport presets (1200×628, 1600×900, 1920×1080, 800×450), and save results locally or directly into the native WordPress Media Library.

The utility features complex lightweight filtering math including granular levels (black/white points), gamma distribution modifications, contrast adjustment matrices, pixel saturation alterations, channel-specific balances, high-pass sharpening kernels, and gray/heat/cyan/gold color mappings.

For WordPress developers and open-source creators, this workspace functions as a complete asset generation kit to build graphics for the official WordPress.org plugin repository. Using the specialized "Download For Plugin" pipeline, the utility automatically scales and center-crops any source image into the four exact required deployment formats: a normal banner (banner-772x250.jpg), a high-DPI retina banner (banner-1544x500.jpg), a standard square icon (icon-128x128.png), and a high-DPI retina square icon (icon-256x256.png). These can be downloaded instantly in a single action to place directly inside your SVN assets directory.
