What It Does

Images to WebP converts existing PNG, JPG, and GIF files in your WordPress media library into the smaller WebP format, helping pages load faster and use less bandwidth. It handles the format conversion directly on your server, delivering modern image formats to visitors without requiring manual edits.

Who It's For

This plugin is a good fit for site owners running image-heavy blogs, photography portfolios, or small ecommerce stores who want a lightweight, single-purpose tool to serve WebP images without adopting a full optimization suite. It is especially useful on hosts that lack built-in image conversion features.

Who Should Skip It

If you already use a caching or optimization plugin like LiteSpeed Cache, EWWW Image Optimizer, or ShortPixel that includes WebP conversion, adding this plugin is redundant. Larger sites with complex media workflows or those needing advanced features like bulk resizing and CDN delivery will outgrow it quickly.

The Bottom Line

Images to WebP does one job and does it well, earning a 78.41 overall quality score backed by recent maintenance and solid user ratings. Its limited support history and small install base mean it carries some risk for business-critical sites, but for a straightforward WebP conversion tool it delivers real value. Consider it a practical choice for smaller sites that do not already get WebP delivery from another plugin.
