WebP Optimizer

WebP Optimizer converts WordPress media library JPEG and PNG images to WebP format through the built-in optimization service. It supports individual attachment conversion, batch conversion from a dedicated Media Library page, and conversion logs with basic file-size statistics.

Features

• Single Image Conversion – Convert individual images directly from the Media Library edit screen
• Bulk Conversion – Convert multiple images at once from the dedicated Bulk Convert page
• Media Library Integration – See WebP conversion status and statistics in the Media Library
• Configurable Quality – Adjust compression quality from 1-100
• Optimization Levels – Choose from Ultra, High, Balanced, or Fast conversion preferences
• Conversion Logs – Track all conversions with detailed statistics
• Supported Formats – JPEG and PNG images can be converted to WebP

How It Works

1. Install and activate the plugin
2. Set your preferred quality and optimization level in Settings > WebP Optimizer
3. Convert images individually from the Media Library or use the Bulk Convert page

Backend Requirements

This plugin uses a built-in WebP optimization service. You do not need to enter or configure a service endpoint.

External services

This plugin connects to an external WebP conversion service to convert JPEG and PNG images into WebP files. The service is required for the single-image and bulk conversion features because the image conversion is performed by that external service.

The service is hosted at https://convert-to-webp-delta.vercel.app/ and is provided by maliktanveer.

When an authorized WordPress user starts a single-image or bulk conversion, the plugin sends the selected image file to the service. The request also includes the original filename, selected quality setting, enhancement preference, optimization level, and optimization priority. The service processes the submitted image and returns the converted WebP file to the WordPress site.

The plugin may also send a connection check request to the service health endpoint. This request does not include image file data.
