Are you frustrated by a slow website? Do over-sized images make you say “ewww”… Let EWWW Image Optimizer help you make your site faster, improve your bounce rate, and boost your SEO. But most importantly, make your visitors happier so they keep coming back for more.

With EWWW IO you can optimize all your existing images, from any plugin, and then let EWWW IO take care of new image uploads automatically.

Why use EWWW Image Optimizer?

EWWW IO is the only plugin that lets you optimize images using tools on your own server (jpegtran, optipng, pngout, pngquant, gifsicle, cwebp). If you feel the need for more speed, get more compression and offload the CPU-intensive process of optimization to our specialized servers.

With Easy IO, images are automatically compressed, scaled to fit the page and device size, lazy loaded, and converted to the next-gen WebP format.

Stuck? Feeling like maybe you DO need that rocket science degree? We provide free one-on-one email support to everyone. Do you have an idea to make EWWW IO even better? Share it and vote on future features! Found a bug? Report the issue on GitHub, and we’ll get it fixed!

Optimize all your images from a single page. This includes the Media Library, your theme, and a handful of pre-configured folders (see Optimize Everything Else below). GRAND FlaGallery, NextCellent and NextGEN have their own Bulk Optimize pages.

Configure any folder within your WordPress install to be optimized. The Bulk Optimizer will compress theme images, BuddyPress avatars, BuddyPress Activity Plus images, Meta Slider slides, WP Symposium Pro avatars, GD bbPress attachments, Grand Media Galleries, and any user-specified folders. You can also use Scheduled optimization or run the optimizer from WP-CLI if that’s more your thing.

EWWW IO has been tested with hundreds (if not thousands) of plugins and themes, here are just a few of the most common ones: BuddyPress (Activity Plus add-on too), Cloudinary, Easy Watermark, FileBird, FooGallery, GD bbPress Attachments, GRAND FlAGallery, Gmedia Photo Gallery, MediaPress, Meta Slider, Microsoft Azure Storage, MyArcadePlugin, NextGEN Gallery, Regenerate Thumbnails, Weglot, WP Offload Media, WPML, WP Retina 2x, WP RSS Aggregator, WP Symposium.

If you want simple, get automatic WebP conversion with Easy IO, and be done with it! Otherwise, you can generate WebP versions of your images with the Bulk Optimizer, and deliver them to supported browsers. Take your pick between Apache-style rewrite rules, JS WebP Rewriting, and WebP Rewriting. EWWW IO even works with the WebP option in the Cache Enabler plugin from KeyCDN.

Allows you to run all Bulk Optimization processes from your command line, instead of the web interface. It is much faster, and allows you to do things like run it in ‘screen’ or via regular cron (instead of wp-cron, which can be unpredictable on low-traffic sites). Install WP-CLI from wp-cli.org, and run ‘wp-cli.phar help ewwwio optimize’ for more information or see the Docs.

WP Offload Media is the officially supported (and recommended) plugin for uploads to Amazon S3, Digital Ocean Spaces, and Google Cloud Storage. Check our compatibility list for details on other plugins. All pull mode CDNs like Cloudflare, KeyCDN, MaxCDN, and Sucuri CloudProxy work automatically, but will require you to purge the cache after a bulk optimization.

Written by Shane Bishop with special thanks to my Lord and Savior. Based upon CW Image Optimizer, which was written by Jacob Allred at Corban Works, LLC. CW Image Optimizer was based on WP Smush.it. Jpegtran is the work of the Independent JPEG Group. PEL is the work of Martin Geisler, Lars Olesen, and Erik Oskam. Easy IO and HTML parsing classes based upon the Photon module from Jetpack.

If these steps do not work, see the additional documentation. If you need further assistance using the plugin, please visit our Support Page.

EWWW IO will remove metadata by default, but if you need to keep the EXIF/IPTC data for copyright purposes, you can disable the Remove Metadata option. EXIF data does not impact SEO, and it is recommended by Google (and just about everyone else) to remove EXIF data.

Yes, but only if the optimized version is smaller. The plugin should NEVER create a larger image.

Yes, you can, set it up on the Resize tab.

Our premium compression can determine the ideal quality setting and give you the best results, but you may also adjust the default quality for conversion and resizing. Read more…

See https://docs.ewww.io/article/39-bulk-optimizer-failure for full troubleshooting instructions.

I’ve tested it on Windows (with Apache), Linux, Mac OSX, FreeBSD, and Solaris. The Compress API and Easy IO CDN will work on any OS.

That’s not a question, but since I made it up, I’ll answer it. See this resource: https://developers.google.com/web/tools/lighthouse/audits/optimize-images
