Image Converter for WebP

73 Quality Score

Active Installs

14/30

With only 2,000 active installs, this plugin has minimal market presence compared to category leaders like Smush (1,000,000 installs) and Converter for Media (500,000 installs), suggesting limited community trust.

The plugin received a perfect maintenance score because it was last updated on 2026-03-23 and is tested with the latest WordPress version 6.9.4, showing active development and current compatibility.

User Rating

12/15

The 100/100 rating is based on just 4 user reviews, which is too small a sample size to be statistically meaningful and could reflect selection bias from early adopters only.

What It Does

This plugin converts existing JPG and PNG images in your WordPress media library to WebP format, a more efficient image codec that reduces file sizes while maintaining visual quality. It processes images automatically and serves the WebP versions to browsers that support the format, falling back to original formats for older browsers.

Who It's For

Site owners with large image libraries who want to improve page load times without manually optimizing images or hiring developers. It works well for photography portfolios, e-commerce sites, news outlets, and any content-heavy WordPress site where image delivery speed impacts user experience and SEO.

Who Should Skip It

Users running WordPress versions below 4.0 or PHP below 7.4 cannot use this plugin. Sites with minimal images or those already using dedicated image optimization services like Cloudflare or a CDN with built-in WebP conversion may find this redundant.

The Bottom Line

Image Converter for WebP does one job: convert images to WebP format for faster delivery. The plugin is actively maintained and compatible with current WordPress versions, but its very small install base (2,000 active sites), minimal support threads, and small review sample make it a risky choice. If WebP conversion is your only need, larger competitors like Converter for Media or Smush offer the same feature with significantly better track records and additional image optimization capabilities.
