EWWW Image Optimizer Cloud

Reduce file sizes for images within WordPress including NextGEN, GRAND FlAGallery and more via paid cloud service.

EWWW Image Optimizer Cloud is a WordPress plugin that will automatically and losslessly optimize your images as you upload them to your blog. It can also optimize the images that you have already uploaded in the past. It is also possible to convert your images automatically to the file format that will produce the smallest image size (make sure you read the WARNINGS).

By default, EWWW Image Optimizer Cloud uses lossless optimization techniques, so your image quality will be exactly the same before and after the optimization. The only thing that will change is your file size. The one small exception to this is GIF animations. While the optimization is technically lossless, you will not be able to properly edit the animation again without performing an --unoptimize operation with gifsicle. The gif2png and jpg2png conversions are also lossless but the png2jpg process is not lossless.

Images are optimized via cloud servers that utilize jpegtran, optipng, and gifsicle. Images can optionally be converted to the most suitable file format.

EWWW Image Optimizer Cloud offloads all optimization to designated servers which will work on any hosting platform. This can be desirable if you do not want to use the exec() function on your server, or prefer to offload the cpu demands of optimization for any reason. This is an ideal setup for web developers who can install this plugin for their clients with no risk due to the potentially insecure exec() function.

Why use EWWW Image Optimizer Cloud?

  1. Your pages will load faster. Smaller image sizes means faster page loads. This will make your visitors happy, and can increase ad revenue.
  2. Faster backups. Smaller image sizes also means faster backups.
  3. Less bandwidth usage. Optimizing your images can save you hundreds of KB per image, which means significantly less bandwidth usage.
  4. Better Privacy. The cloud servers do not store any images after optimization is complete, and you retain all rights to any images processed via the cloud service.
  5. Root access not needed No binaries needed on your local server, so it works on any hosting platform.
  6. Optimize almost anything Using the Optimize More tool, and the wp_image_editor class extension, any image in WordPress can be optimized.

If you want to optimize images on your own server without using the cloud, see the EWWW Image Optimizer.

Bulk Optimize

There are two functions on the Bulk Optimize page. One is to optimize all images in the Media Library. The Scan and Optimize is for everything else. Officially supported galleries (GRAND FlaGallery and NextGEN) have their own Bulk Optimize pages.

Skips Previously Optimized Images

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 additionally choose to empty the table, remove individual images from the list, or use the Force optimize option to override the default behavior. Before running the Bulk Optimize the first time, you must run an import operation that scans your Media Library for any previously optimized images (from before version 1.8.0). The re-optimize links on the Media Library page also force the plugin to ignore the previous optimization status of images.

WP Image Editor

All images created by the new WP_Image_Editor class in WP 3.5 will be automatically optimized. Current implementations are GD, Imagick, and Gmagick. Images optimized via this class include Meta Slider, BuddyPress Activity Plus (thumbs), WP Retina 2x, Imsanity, Simple Image Sizes and probably countless others. If you have a plugin that uses WP_Image_Editor and would like EWWW IO to be able to optimize previous uploads, post a thread in the support forums.

Optimize Almost Everything

As of version 1.7.0, site admins can specify any folder within their wordpress folder to be optimized. The 'Optimize More' option under Tools will optimize theme images, BuddyPress avatars, BuddyPress Activity Plus images, Meta Slider slides, WP Symposium images, GD bbPress attachments, and any user-specified folders. Additionally, this tool can run on an hourly basis via wp_cron to keep newly uploaded images optimized. Schedule optimization does NOT include Media Library images, because they are already optimized on upload.

NextGEN Gallery

Features optimization on upload capability, re-optimization, and bulk optimizing. The NextGEN Bulk Optimize function is located near the bottom of the NextGEN menu, and will optimize all images in all galleries. It is also possible to optimize groups of images in a gallery, or multiple galleries at once. NOTE: Does not optimize thumbnails on initial upload for legacy (1.9.x) versions of NextGEN, but instead provides a button to optimize thumbnails after uploading images.

GRAND Flash Album Gallery

Features optimization on upload capability, re-optimization, and bulk optimizing. The Bulk Optimize function is located near the bottom of the FlAGallery menu, and will optimize all images in all galleries. It is also possible to optimize groups of images in a gallery, or multiple galleries at once.


Located under Media, the BuddyPress Optimizer allows the user to optimize all avatars (group and individual). Stores a history of optimized images, so that you can optimize new images without re-optimizing old images.

Image Store

Uploads are automatically optimized. Look for Optimize under the Image Store (Galleries) menu to see status of optimization and for re-optimization and bulk-optimization options. Using the Bulk Optimization tool under Media Library automatically includes all Image Store uploads.
