EWWW Image Optimizer Cloud


The EWWW Image Optimizer (cloud edition) will increase your page speeds by way of image optimization. Increased page speeds can result in better search engine rankings, and will also improve conversion rates (increased sales and signups). It will also save you storage space and bandwidth. While EWWW I.O. will automatically optimize new images that you upload, it can also optimize all the images that you have already uploaded, and optionally convert your images to the best file format. You can choose pixel perfect compression or high compression options that are visually lossless. The cloud edition features all the same options as the core EWWW Image Optimizer without the security risk associated with the exec() function. Built exclusively for the EWWW I.O. API, it is lightweight and much quicker when updating.

EWWW I.O. will optimize images uploaded and created by any plugin, and features special integrations with many popular plugins, detailed below.

Why use EWWW Image Optimizer?

  1. No Speed Limits and unlimited file size.
  2. Smooth Handling with pixel-perfect optimization using industry-leading tools and progressive rendering.
  3. High Torque as we bring you the best compression/quality ratio available with our lossy options for JPG, PNG, and PDF files.
  4. Adaptive Steering with intelligent conversion options to get the right image format for the job (JPG, PNG, or GIF).
  5. Metered Parking means you never pay for an image we can’t compress, you are never billed for a month you do not use the API, and pre-paid credits never expire. Plus, get WebP image generation at no extra cost: any JPG or PNG can be converted to Google’s next-generation image format.
  6. Comprehensive Coverage: no image gets left behind, optimize everything on your site, beyond just the WordPress Media Library.
  7. Safety First: all communications are secured with top SSL encryption.
  8. Roadside Assistance: top-notch support is in our DNA. For priority assistance, be sure to use your registered email or mention your registered email when you contact us for help.
  9. Pack a Spare: free image backups store your original images for 30 days.

Images are optimized via specialized servers that utilize the best tools available in lossless or lossy mode. Our lossy compression uses unique algorithms to gain maximum compression while remaining visually lossless. Your images can even be converted to the most suitable file format using the appropriate options. Using the EWWW I.O. API will allow the plugin to work on any hosting platform, and can also be desirable if you cannot, or do not want to use the exec() function on your server, or prefer to offload the resource demands of optimization.

Automatic Resizing

With ExactDN support, images will be automatically resized to fit the page and device size. ExactDN also enables basic retina support and automatic compression.

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

Optimiere alles andere

Konfiguriere beliebige Ordner innerhalb der WordPress-Ordner, die optimiert werden sollen. Die „Scanne und optimiere“-Option unter Medien->Massenoptimierung wird Theme-Bilder, BuddyPress Avatare, BuddyPress Activity Plus Bilder, Meta Slider Slides, WP Symposium Bilder, GD bbPress Anhänge, Grand Media Galerien und alle individuell angegebenen Ordner optimieren. Zusätzlich kann dieses Werkzeug auf stündlicher Basis mittels wp_cron laufen, um neu hochgeladene Bilder optimiert zu halten. Geplante Optimierung sollte nicht für Plugins genutzt werden, die die in WordPress eingebauten Bildfunktionen benutzen.

Überspringt bereits optimierte Bilder

All optimized images are stored in the database so that the plugin does not attempt to re-optimize them unless they are modified. On the Bulk Optimize page you can view a list of already optimized images. You may also remove individual images from the list, or use the Force optimize option to override the default behavior. The re-optimize links on the Media Library page also force the plugin to ignore the previous optimization status of images.

WP Bild Editor

Alle Bilder, die durch die eingebaute WP_Image_Editor-Klasse erstellt wurden, werden automatisch optimiert. Derzeitige Implementierungen sind GD, Imagick und Gmagick. Bilder, die durch diese Klasse optimiert wurden, beinhalten Animated GIF Resize, BuddyPress Activity Plus (Vorschaubilder), Easy Watermark, Hammy, Imsanity, MediaPress, Meta Slider, MyArcadePlugin, OTF Regenerate Thumbnails, Regenerate Thumbnails, Simple Image Sizes, WP Retina 2x, WP RSS Aggregator und vermutlich zahllose andere. Falls du nicht sicher bist, ob ein Plugin WP_Image_Editor nutzt, frag einfach.


Automatic WebP conversion with ExactDN, no additional configuration. Otherwise, can generate WebP versions of your images, and enables you to serve even smaller images to supported browsers. Several methods are available for serving WebP images, including Apache-compatible rewrite rules and our JS WebP Rewriting option compatible with caches and CDNs. Also 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.


Alle Bilder, die durch FooGallery hochgeladen und gecached werden, werden automatisch optimiert. Vorherige Uploads können mittels der Medienbibliothek Massenoptimierung optimiert werden. Bereits gecachte Bilder können optimiert werden durch Angabe des Verzeichnisses wp-content/uploads/cache/ unter den zu optimierenden Verzeichnissen und einem Aufruf von Scanne & Optimiere auf der Massenoptimierungsseite.

NextGEN Gallery

Bietet Optimierung beim Hochladen, Re-Optimierung, und Massenbearbeitung. Die NextGEN Bulk Optimize Funktion befindet sich nahe des Endes des NextGEN Menüs, und wird alle Bilder in alles Galerien optimieren. Es ist auch möglich Gruppen von Bildern in einer Galerie, oder mehrere Galerien auf einmal zu optimieren.

NextCellent Gallery

Bietet dieselben Möglichkeiten wie NextGEN, und ist die Fortsetzung des NextGEN Supportes für (1.9.x)

GRAND Flash Album Gallery

Bietet Optimierung beim Hochladen, Re-Optimierung, und Massenbearbeitung. Die Massenoptimierung Funktion befindet sich nahe des Endes des FlAGallery Menüs, und wird alle Bilder in allen Galerien optimieren. Es ist auch möglich Gruppen von Bildern in einer Galerie, oder mehrere Galerien auf einmal zu optimieren.

Image Store

Uploads werden automatisch optimiert. Schau nach Optimiere im Image Store (Galerien) Menu, um den Status der Optimierung zu sehen und für Re-Optimierungs- und Massenbearbeitungs-Optionen. Die Benutzung der Massenbearbeitung unter der Mediathek beinhaltet automatisch alle Image Store Uploads.

CDN Unterstützung

WP Offload Media is the officially supported (and recommended) plugin for uploads to Amazon S3 and Digital Ocean Spaces. We also support the Azure Storage and Cloudinary 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.

WPML Compatible

Tested regularly to ensure compatibility with multilingual sites. Learn more at https://wpml.org/plugin/ewww-image-optimizer/

Google Pagespeed behauptet, meine Bilder benötigen Kompression oder Größenänderung, aber ich habe bereits alle meine Bilder optimiert. Was soll ich tun?


Ersetzt das Plugin existierende Bilder?

Ja, aber nur wenn die optimierte Version kleiner ist. Das Plugin wird NIEMALS ein größeres Bild erzeugen.

Kann ich die Größe meiner Bilder mit diesem Plugin verändern?

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

Kann ich die Kompressionsrate für JPGs erniedrigen um mehr Platz zu sparen?

The lossy JPG optimization using TinyJPG and JPEGmini will determine the ideal quality setting and give you the best results, but you can also adjust the default quality for conversion and resizing. More information: https://docs.ewww.io/article/12-jpq-quality-and-wordpress

Die Massenoptimierung scheint nicht zu funktionieren, was kann ich tun?

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

Ich möchte mehr über Bildoptimierung erfahren.

That’s not really a question, but since I made it up, I’ll answer it. See this resource:

The support for this plugin is outstanding. The developer really listens and solves problems quickly. It works great and is easy to setup. Thank you 🙂

I am using the cloud version and it seems to work. My issue is with "sizing" your site according to their billing criteria. It's entirely unclear with the cloud version if it calculates the images correctly including the various thumbnails. The communication around the 99c monthly is also not clear as to what happens when that runs out can you buy more or do you now have to wait until the next billing cycle. This uncertainty is not encouraging there needs to be more clarity.

We use the Cloud version, since we host most of our sites at WP Engine (and they don't allow the non-Cloud version on their servers). Great options, works well. I especially like that it converts PNGs to JPGs, since PNG photographic images tend to be VERY large, while JPGs tend to be 10% the size of an equivalent PNG.

Signed up for the $1 for a huge number of images deal. Billed 6 bucks 30 days later and am told that even though I only have a few dozen images on my entire web site, I used thousands of images. Huh? Scammer…I am a neophyte, admittedly, but I don’t think the app does anything except infiltrate your system. I notice absolutely no difference with or without the app. That says a lot. We are talking a few dollars here…but I wouldn’t mind a few dollars from a few hundred people every month for doing nothing.

The support from the plugin author is excellent. This is the only plugin that I managed to get it to work with WP S3 Offload plugin. If you want your site to load fast, with only a slight lag to upload/process speed on the editor, this plugin is a must.
