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.


If you need assistance using the plugin, please visit our Support Page.

Ottimizzazione Bulk

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.

Ottimizzare tutto il resto

Configure any folder within your WordPress folder to be optimized. The Bulk Scan under Media->Bulk Optimize will optimize 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. Additionally, this tool can run on an hourly basis via wp_cron to keep newly uploaded images optimized. Scheduled optimization should not be used for any plugin that uses the built-in WordPress image functions.

Evitare le immagini già ottimizzate

Tutte le immagini ottimizzate sono archiviate nel database in modo che il plugin non tenti di ri-ottimizzarle a meno che non siano state modificate. Sipuò vedere un elenco delle immagini già ottimizzate sulla pagina di Ottimizzazione Bulk. Si possono rimuovere dall’elenco delle singole immagini oppure usare l’opzione di Ottimizzazione Forzata per scavalcare l’impostazione di comportamento predefinita. i collegamenti alla ri-ottimizzazione sulla pagina della Libreria dei Media, allo stesso modo, forzabo il plugin ad ignorare lo stato precedente di ottimizzazione delle immagini

Editor di Immagini WP

All images created by the built-in WP_Image_Editor class will be automatically optimized. Current implementations are GD, Imagick, and Gmagick. Images optimized via this class include Animated GIF Resize, BuddyPress Activity Plus (thumbs), Easy Watermark, Hammy, Imsanity, MediaPress, Meta Slider, MyArcadePlugin, OTF Regenerate Thumbnails, Regenerate Thumbnails, Simple Image Sizes, WP Retina 2x, WP RSS Aggregator and probably countless others. If you are not sure if a plugin uses WP_Image_Editor, just ask.

Immagini WebP

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.


Tutte le immagini caricate e messe nella cache di FooGallery vengono ottimizzate automaticamente. I caricamenti precedenti possono essere ottimizzati eseguendo l’Ottimizzazione Bulk della Libreria dei Media. Le immagini messe precedentemente nella cache possono essere ottimizzate inserendo la cartella wp-content/uploads/cache/ nelle Cartelle da Ottimizzare ed eseguendo Scansione & Ottimizzazione dalla pagina delle Ottimizzazioni Bulk.

Galleria NextGEN

Capacità di ottimizzazione al caricamento, ri-ottimizzazione e ottimizzazione bulk. La funzione di Ottimizzazione Bulk di NextGEN si trova vicino al fondo del menu NextGEN, e ottimizzerà tutte le immagini in tutte le gallerie. Si possono ottimizzare in una volta anche gruppi di immagini o gallerie multiple.

Galleria NextCellent

Possiede le tutte stesse capacità di NextGEN, ed è la prosecuzione del suporto NextGEN originario (1.9.x).

Galleria GRAND Flash Album

Possiede le capacità di ottimizzazione al caricamento, ri-ottimizzazione e ottimizzazione bulk. La funzione di Ottimizzazione Bulk di si trova vicino al fondo del menu FlAGallery, e ottimizzerà tutte le immagini in tutte le gallerie. Si possono ottimizzare in una volta anche gruppi di immagini o gallerie multiple.

Negozio Immagini

I caricamenti vengono ottimizati automaticamente. Cercare Ottimizza nel menu dello Store Immagine (Gallerie) per vedere lo stato dell’ottimizzazione e per trovare le opzioni di ri-ottimizzazione e ottimizzazione bulk. Usando lo strumento di Ottimizzazione Bulk nella Libreria dei Media si includeranno automaticamente tutti i caricamenti dello Store Immagine.

Supporto CDN

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 dice che le mie immagini hanno bisogno di essere compresse o ridimensionate, nonostante le abbia già ottimizzate. Che cosa faccio?


Il plugin sostituisce le immagini esistenti?

Sì, ma solo se la versione ottimizzare è più piccola. Il plugin non dovrebbe MAI creare un’immagine più grande.

Posso ridimensionare le mie immagini con questo plugin?

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

Posso abbassare il valore della compressione dei JPG per risparmiare spazio?

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

Il bulk optimizer non sembra funzionare, che cosa posso fare?

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

Voglio sapere di più sull’ottimizzazione delle immagini.

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

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.
