<p>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 <a href="https://ewww.io/plans/" rel="nofollow ugc">our specialized servers</a>.</p>

The Patchstack team helps validate, triage and handle any security vulnerabilities. <a href="https://patchstack.com/database/vdp/ewww-image-optimizer" rel="nofollow ugc">Report a security vulnerability.</a></p>
<h4>Bulk Optimize</h4>
<p>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.</p>
<h4>Optimize Everything Else</h4>
<p>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.</p>
<h4>Plugin Compatibility</h4>
<p>EWWW IO has been tested with hundreds (if not thousands) of <a href="https://docs.ewww.io/article/84-plugin-compatibility" rel="nofollow ugc">plugins and themes</a>, 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, <a href="https://weglot.com/integrations/wordpress-translation-plugin/demo/" rel="nofollow ugc">Weglot</a>, WP Offload Media, <a href="https://wpml.org/plugin/ewww-image-optimizer/" rel="nofollow ugc">WPML</a>, WP Retina 2x, WP RSS Aggregator, WP Symposium. <a href="https://docs.ewww.io/article/84-plugin-compatibility" rel="nofollow ugc">Read more…</a></p>
<h4>WebP Images</h4>
<p>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.</p>
<h4>AVIF Images</h4>
<p>AVIF conversion is built into the Easy IO CDN. Once your site is setup with Easy IO, edit the site settings to enable AVIF, and you’re done!</p>
<h4>WP-CLI</h4>
<p>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 <a href="https://docs.ewww.io/article/25-optimizing-with-wp-cli" rel="nofollow ugc">Docs</a>.</p>
<h4>CDN Support</h4>
<p><a href="https://wordpress.org/plugins/amazon-s3-and-cloudfront/" rel="ugc">WP Offload Media</a> is the officially supported (and recommended) plugin for uploads to Amazon S3, Digital Ocean Spaces, and Google Cloud Storage. <a href="https://docs.ewww.io/article/84-plugin-compatibility" rel="nofollow ugc">Check our compatibility list for details on other plugins</a>. 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.</p>

EWWW Image Optimizer

Serve webp images with fallback for browser which don't support

Excellent plugin!

I installed Imsanity which is another plugin I love and it recommended the EWWW Image Optimizer and I installed it and it drastically cut down the file size of the images as well as converting them to different file formats! I was so impressed it was so easy to use and the optimized images looked super fantastic! I couldn't tell the difference and it optimized all sizes of the different sizes that WordPress creates and it handled it all! Super thrilled to have found this gem!

I love this plugin!


Very nice plugin that does the job. We have used this plugin in number of our websites.


Nice plugins that works for free

Fantastic

Works perfect - I loved it


Useless plug-in! They force you to register on their site and you have to pay! But that's not all, you can't delete your account and you can't contact them. They use your personal data to spam you with useless emails. Misleading methods that have nothing to do with Wordpress.org


useless plugin

Class A tool to minify images


Does a good job at optimizing images. 



Full disclosure: I'm leaving this review because I'm sick of seeing the nag in my admin, which I prefer to keep unmolested by the promotional efforts of plugin authors.


Easy to use


I have been using EWWW for 3 years now and never had any issues. So, kudos to that and for this great tool.


My go-to image optimization plugin


WP Core 6.5 has added AVIF support, yet EWWW IO still doesn't support it.  Seems like just an excuse to push people to use their paid CDN service Easy IO.  I've been a long time user of EWWW IO but now it seems like the it doesn't do much of anything useful anymore.  


Failed to keep up with standards, no AVIF support


Very useful for tuning up WordPress site. Thanks for a great plugin!


Very useful and highly functional plugin!


Totally solved page speed issues on premium, it is the oldest plugin for image optimization on WP as far as I know


Great and Simple

Smaller Images, Faster Sites, Happier Visitors. Comprehensive image optimization that doesn't require a degree in rocket science.
