Frequently Asked Questions

The EWWW Image Optimizer is the only plugin that can compress images for free directly on your site without any third-party API/service. While many web hosts allow this sort of “local” compression, not all do. For sites that can’t do local compression, we offer free JPG-only cloud-based compression (unlimited images and file size).

Thus, certain features, like PNG, GIF, and SVG compression, only work in local compression mode. Additionally, since PNG compression only works with local mode, PNG to WebP conversion can only be done if local mode is allowed by your web host.

First off, top-notch support is in our DNA. Regardless of whether you pay us or not, we answer every single support question with care. So while everyone gets the same great support, paying customers just get it faster than everyone else.

The easiest place to start for non-WordPress sites is our Easy IO CDN. You can implement it just like you would any CDN (like Cloudfront, Bunny, or KeyCDN). Beyond that, you can take advantage of advanced features like scaling and cropping.

If you need to save on storage, or don’t want to use a CDN, the Compress API can be used to compress images practically anywhere. We have a PHP-based library, or a CLI app called SILO that features API and local/free compression.

Our SWIS Performance plugin is WordPress-only, and we have no plans to port it to other platforms.
