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.

This workspace is also highly optimized for open-source project managers and creators. It functions as a complete asset generation kit for designing official WordPress plugin repository graphical banners and display icons. The built-in asset bundle automated process isolates, scales, center-crops, and delivers standard repository dimensions directly to your machine.
