<p>Automatically create human readable labels for custom image sizes created with <code>add_image_size()</code> so that they’re selectable in the WP admin.  For example, when you insert media into a post, in the Attachment Display Settings->Size select list, your custom image size will now be available.  The plugin uses the <code>image_size_names_choose</code> filter as described <a href="https://developer.wordpress.org/reference/functions/add_image_size/" rel="nofollow ugc">here</a> in the For Media Library Images (Admin) section.  By default the human readable name is the ‘name’ variable given to <code>add_image_size()</code> stripped of non-alphanumeric characters and the first letter of each word in uppercase.</p>


Human Readable Custom Image Sizes

Automatically create human readable labels for custom image sizes created with add_image_size() so that they're selectable in the WP admin.

<p>Found a bug? Report the issue on <a href="https://github.com/nosilver4u/ewww-image-optimizer" rel="nofollow ugc">GitHub</a>, and we’ll get it fixed!</p>
<p>You may report security issues through our Patchstack Vulnerability Disclosure Program. 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 images, all 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 optimize images. 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 Image Optimizer has been tested with 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">and 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 unlimited images with the Bulk Optimizer. Deliver them to supported browsers with Apache-style rewrite rules, JS WebP Rewriting, or Picture WebP Rewriting. EWWW Image Optimizer 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 batch image processes from the command line, instead of the web interface. Optimize images even faster, 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, Bunny CDN and Sucuri work automatically, but you will need to purge the CDN cache after you optimize images with 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

Comprehensive image optimization with WebP, AVIF, Lazy Load, and more. Optimize images automatically for Faster Sites and Happy Visitors.
