What is Converter for Media?

Converter for Media is a WordPress image optimization plugin that automatically converts JPEG, PNG, and GIF files into WebP and AVIF formats. It was created by developer Mateusz Gbiorczyk and has been available for 7 years. The plugin currently has over 500,000 active installs and holds a 4.9 out of 5 rating from 1,088 reviews. A full 96% of those reviews are five-star, indicating consistent user satisfaction across a large install base.

The plugin works by replacing standard image files with lighter WebP or AVIF copies. It does not modify your original images. Instead, it stores converted files in a separate /wp-content/uploads-webpc/ directory. This approach ensures safety and makes removal simple. When you delete the plugin, it removes all converted files without leaving any trace.

Key Features of Converter for Media

  • One-Click Library Optimization – Convert your entire Media Library with a single action. No batch processing or manual selection is needed.
  • Automatic New Image Conversion – Any image added to the Media Library after setup is converted automatically without extra effort.
  • AVIF Support (PRO Version) – Use AVIF as your output format for images that are about 50% lighter than WebP, while maintaining better quality.
  • Automatic Browser Fallback – The plugin serves AVIF to supported browsers, WebP to others, and original files to older browsers. This covers over 90% of modern browsers for AVIF and over 95% for WebP.
  • No Original File Modification – Your source JPEG, PNG, and GIF files remain untouched. Converted files are stored separately for complete safety.
  • Server Load Reduction – Smaller image files decrease bandwidth usage and reduce the processing load on your server.
  • SEO and Ranking Benefits – Faster page load times from optimized images contribute to better Google ranking performance.
  • Full Plugin Cleanup on Deactivation – Removing the plugin clears all converted files and settings, leaving your site exactly as it was before installation.
