Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

WP PlugIndex currently records Halka WebP Image Optimizer version 1.0.0 as active, updated 7mo ago and tested up to WordPress 6.9.
Overview
About this plugin
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

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
