About
Serve autogenerated WebP images instead of jpeg/png to browsers that supports WebP.
Security History
What It Does
WebP Express converts JPEG and PNG images on your site into WebP format on the fly and serves the smaller WebP files to browsers that support them, while falling back to the originals for older clients. It handles the conversion automatically without requiring you to manually re-upload your media library. The result is smaller image payloads and faster page loads for most modern visitors.
Who It's For
This plugin is a good fit for site owners running photography portfolios, e-commerce stores, image-heavy blogs, or news sites where large media libraries are hurting page speed and Core Web Vitals. It is especially useful for users on shared hosting or non-LiteSpeed servers who do not have a built-in WebP solution. Anyone looking to modernize image delivery without redesigning their entire workflow will benefit.
Who Should Skip It
If you are already running LiteSpeed Cache on a LiteSpeed server, you get WebP conversion built in and do not need this plugin. Sites with very few images, or those already using a full-stack optimization plugin that includes WebP conversion (such as Jetpack Boost or ShortPixel), can safely skip it to avoid overlapping tooling.
The Bottom Line
WebP Express is a focused, well-maintained plugin that does one thing and does it well, with a perfect maintenance record and broad compatibility. The main concern is the support channel, which shows no resolved threads, so users should be comfortable troubleshooting with documentation rather than expecting fast ticket responses. For sites that need straightforward WebP delivery without a heavyweight cache plugin, it remains a strong choice with an overall quality score of 85.23 out of 100.
Related Plugins
Pick this instead if your host runs LiteSpeed servers, since it handles WebP conversion as part of a much broader caching and optimization suite.
Choose Jetpack if you want WebP delivery bundled with security, backups, and growth tools rather than as a standalone image utility.
Redis Object Cache solves a different problem (database performance) and is not a substitute, but it can complement WebP Express on high-traffic sites.
Pick this if your site sits behind Cloudflare and you want edge caching combined with image optimization at the CDN level.
Choose EWWW if you want to compress and convert images at upload time with bulk optimization tools, rather than relying on on-the-fly conversion.
