Auto WebP Converter & Logger Reviews, Downloads & Maintenance

Auto WebP Converter & Logger is a lightweight, powerful plugin designed to optimize your website’s media library. It automatically converts JPEG and PNG images to the WebP format during upload — significantly reducing file size without sacrificing quality. It also logs each conversion (or failure) and supports uploads from both the Media Library and third-party plugins like Instant Images.

Key Features:

Automatic WebP Conversion: Converts JPEG and PNG images to the WebP format on upload.
Custom Quality Setting: Define your preferred WebP image quality (0-100).
Original File Handling: Choose whether to delete the original JPEG/PNG after successful conversion.
Detailed Logging: Enable logging of all conversions and errors in a secure log file.
GD Library Check: Automatically detects if the GD library is missing and shows admin notices.
Secure and Optimized: Only images smaller than 10MB are processed for optimal performance.
Admin Settings Panel: Easy-to-use settings page under WordPress Settings > Images to WebP.

Important:
Requires the GD library with WebP support enabled on your server.

Installation

Upload the auto-webp-converter-logger folder to the /wp-content/plugins/ directory.
Activate the plugin through the ‘Plugins’ menu in WordPress.
Navigate to ‘Settings’ > ‘Images to WebP’ to configure your preferences.

Frequently Asked Questions

What image formats does this plugin convert?

Currently, it supports JPG, JPEG and PNG images.

Where is the WebP conversion log saved?

The plugin creates a autoweco-webp-conversion-log.txt file inside the uploads folder (wp-content/uploads).

Can I delete the original images after conversion?

Yes, you can enable or disable this option in the plugin settings.

What if my server does not support WebP?

If the required GD library functions are missing, the plugin will display an admin notice. In that case, image conversion will not work.

What happens if the uploaded file is too large?

Images larger than 10MB are automatically skipped for performance reasons. The event is logged if logging is enabled.

Will this work with third-party image upload plugins like Instant Images?

Yes — the plugin ensures the correct MIME type is saved even if uploads bypass the default flow.
