About this plugin
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.
