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.
