Halka WebP Image Optimizer
Halka WebP Image Optimizer hooks into the WordPress upload pipeline to silently convert JPEG and PNG images to WebP during upload. It is a minimalist, performance-first optimizer. Unlike “bloated” suites, Halka focuses on a zero-configuration approach to keep your server load light (“Halka” means light). It is designed for users who want WebP conversion without the database overhead of larger plugins. No external APIs, no credits required — everything happens locally on your server. Features Convert JPEG, PNG (and optionally GIF) to WebP on upload Configurable quality per format Optional maximum dimension cap (auto-resize on upload) Strip EXIF/IPTC metadata to save extra bytes Optionally delete the original file after conversion Bulk converter — process existing Media Library images in small batches Per-image Convert to WebP button in the Media Library list view Server support badge so you know what your host can do Zero external dependencies — uses WordPress’s built-in WP_Image_Editor
