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 optimize your images as you upload them to your blog. It can optimize the images that you have already uploaded, convert your images automatically to the file format that will produce the smallest image size (make sure you read the WARNINGS), and optionally apply lossy reductions for PNG and JPG images.
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. The lossy optimization for JPG and PNG files uses sophisticated algorithms to minimize perceptual quality loss, which is vastly different than setting a static quality/compression level.
Images are optimized via cloud servers that utilize the latest tools available is lossless or lossy mode. Your images can optionally be converted to the most suitable file format.
EWWW Image Optimizer Cloud offloads all optimization to designated servers which will allow the plugin to work on any hosting platform. The lossy compression options use special algorithms to gain maximum compression with minimal loss of quality. Using the EWWW I.O. Cloud can also be desirable if you cannot, or 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?
If you want to optimize images on your own server without using the cloud, see the EWWW Image Optimizer.
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, NextCellent, and NextGEN) have their own Bulk Optimize pages.
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.
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 Meta Slider, BuddyPress Activity Plus (thumbs), WP Retina 2x, Imsanity, Simple Image Sizes, Hammy, Animated GIF Resize and probably countless others. If you are not sure if a plugin uses WP_Image_Editor, post a thread in the support forums.
Site admins can specify any folder within their wordpress folder to be optimized. The 'Scan and Optimize' option under Media->Bulk Optimize will optimize theme images, BuddyPress avatars, BuddyPress Activity Plus images, Meta Slider slides, WP Symposium images, 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, unless you have disabled automatic optimization.
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.
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.
Features all the same capability as NextGEN, and is the continuation of legacy (1.9.x) NextGEN support.
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.
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.
