EWWW Image Optimizer Premium

Optimize WordPress media across your website

EWWW Image Optimizer Premium adds 5x premium picture optimization and PDF optimization for media in the WordPress Media Library, themes and configured folders. Automatic scaling also applies to images referenced in external CSS. Enhanced responsive images use dimensions suited to various devices, and High-DPI delivery works with screens with 2x and 3x pixel density.

Premium includes one-click WebP and AVIF conversion and delivery, watermarking, 30-day cloud-based backups and premium support. You can resize images on upload or in bulk, pick which WordPress thumbnails are created and optimized, preserve GIF animations in thumbnails, adjust JPG and WebP quality, and convert between GIF, PNG and JPG.

Choose how WebP and AVIF images are delivered

The Bulk Optimizer can generate WebP versions of images for compatible browsers. Delivery options include Apache-style rewrite rules, JavaScript WebP Rewriting and Picture WebP Rewriting. Easy IO CDN compresses and scales images to fit page and device dimensions, lazy loads them, and converts them to WebP and AVIF. To use AVIF through Easy IO, set up the CDN and enable AVIF in its site options.

CDN delivery can cover images, CSS, JavaScript and fonts, with an option to use a custom domain name. This can place selected site assets in the same delivery process as image scaling, lazy loading and format conversion.

Run optimization on existing media

Bulk Optimize processes the Media Library, theme images and selected folders from one page. You can configure folders within the WordPress installation, including folders used by supported galleries, sliders, avatars and attachments. Scheduled optimization and WP-CLI are available for repeatable batch processing.

The plugin has been tested with many add-ons and themes, including BuddyPress, Cloudinary, FooGallery, Meta Slider, NextGEN Gallery, WP Offload Media and WPML. Compatibility can vary by setup.

SWIS performance tools are included with Premium plans

Premium plans include the SWIS Performance extension, with page caching, long browser-cache lifetimes, JavaScript and CSS deferral and minification, and Critical CSS generation to help prevent layout shifting. It can also optimize font display, self-host Google Fonts, preload assets such as fonts and LCP images, reduce unused JavaScript and CSS, and manage speculative loading.

Check server requirements for local optimization

Local processing can use server tools such as jpegtran, optipng, pngout, pngquant, gifsicle and cwebp. This mode requires the PHP exec() function and a compatible Linux, Windows, MacOS or FreeBSD server. If the server is incompatible, the Compress API provides lossless JPG optimization and WebP conversion.

Install the plugin in WordPress, then configure the optimization, format delivery, scaling, CDN, backup, watermark and performance options for your site. Use Bulk Optimize for existing media, or scheduled optimization and WP-CLI for ongoing jobs.
