EWWW Image Optimizer


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.

Warum EWWW Image Optimizer benutzen?

  1. Keine Geschwindigkeitsbegrenzungen und unbegrenzte Dateigröße.
  2. Leichtes Handling mit pixelgetreuer Optimierung durch branchenführende Werkzeuge und progressives Rendering.
  3. High Torque as we bring you the best compression/quality ratio available with our Premium compression for JPG, PNG, and PDF files.
  4. Adaptive Steering with intelligent conversion options to get the right image format for the job (JPG, PNG, GIF, or WebP).
  5. Free Parking The core plugin is free and always will be. However, our paid services offer up to 80% compression, and a host of other features!
  6. Comprehensive Coverage: no image gets left behind, optimize everything on your site, not just the WordPress Media Library.
  7. Sicherheit geht vor: Jede Kommunikation wird durch SSL-Verschlüsselung gesichert.
  8. Pannenhilfe: Erstklassige Hilfeleistung ist in unserer DNA. Während API-Kunden höchste Priorität genießen, beantworten wir jede Support-Anfrage sorgfältig.
  9. Ersatzreifen: kostenlose Speicherung von Bild-Backups für 30 Tage.

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.

Automatic Everything

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.

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.

Optimiere alles andere

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.

Plugin Compatibility

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, FooGallery, GD bbPress Attachments, GRAND FlAGallery, Gmedia Photo Gallery, MediaPress, Meta Slider, Microsoft Azure Storage, MyArcadePlugin, NextGEN Gallery, Regenerate Thumbnails, WP Offload Media, WPML, WP Retina 2x, WP RSS Aggregator, WP Symposium.

WebP Bilder

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.


Erlaubt dir, alle Massenoptimierungs-Prozesse in der Kommandozeile auszuführen, statt im Web-Interface. Das ist viel schneller und erlaubt dir Dinge wie Ausführen im ’screen‘ oder via regulärem cron (statt wp-cron, welches auf Websites mit wenig Verkehr unvorhersehbar sein kann). Installiere WP-CLI von wp-cli.org und führe ‚wp-cli.phar help ewwwio optimize‘ aus, für mehr Informationen oder lies die Dokumentation (engl.).

CDN Unterstützung

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.

  • Plugin Einstellungsseite.
  • Spalte Optimierung zur Medienliste hinzugefügt. Du kannst deine Einsparungen sehen, Bilder einzeln optimieren lassen, und Originale wiederherstellen (nur nach Konvertierung).
  • Massenbearbeitungsseite. Du kannst alle deine Bilder auf einmal optimieren und eine vorherige Massenbearbeitung fortsetzen. Dies ist sehr nützlich für bestehende Blogs mit vielen Bildern.


  1. Lade das „ewww-image-optimizer“ Plugin in dein /wp-content/plugins/ Verzeichnis hoch.
  2. Aktiviere das Plugin im ‚Plugins‘ Menu in WordPress.
  3. Das Plugin wird versuchen, jpegtran, optipng, und gifsicle automatisch zu installieren. Dies erfordert, dass der wp-content Ordner vom Benutzer des Webservers beschreibbar ist.
  4. If the binaries don’t run locally, you may sign up for cloud-based optimization: https://ewww.io/plans/
  5. Empfehlung Besuche die Einstellungsseite um spezifische Werkzeuge ein/auszuschalten und fortgeschrittene Optimierungsmöglichkeiten einzustellen.
  6. Fertig!

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

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

Try this for starters: https://docs.ewww.io/article/5-pagespeed-says-my-images-need-more-work

Das Plugin meldet, dass mir etwas fehlt, was soll ich tun?

This article will walk you through installing the required tools (and the alternatives if installation does not work): https://docs.ewww.io/article/6-the-plugin-says-i-m-missing-something

Ersetzt das Plugin bestehende 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?

Ja, das kannst du über den Skalierungs-Tab einstellen.

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

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…

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

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

Welche Betriebssysteme werden unterstützt?

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

Ich möchte mehr über Bildoptimierung erfahren, und warum diese Optionen/Tools gewählt wurden.

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

I have tried 15 image optimization plugins and I have finally found the one for me. EWWW Image Optimizer is the best plugin for me. I have found that it works fantastically well on Virtual Private Servers (VPS) like those provided by UPCloud and digitalocean. I have found that EWWW Image Optimzier does not work well at all on shared hosting environments. You really need a VPS or better to take full advantage of what this plugin has to offer.

The service of image serving is fantastic, but the customer support is the best I have encountered in a while. There were no issues with the software, just conflicts with other plugins' settings that are buried. I highly recommend this plugin!
11. September 2020
I am not sure if it is only me have this experience. I like the theme very much but I found that once I have updated the products/content on the website. It will show blank page on homepage or take a few minutes to load the content. Any suggestions on it?
