The EWWW Image Optimizer 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.

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. 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, 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. While API customers get top priority, we answer every single support question with care.
  9. Pack a Spare: free image backups store your original images for 30 days.

Images can be optimized using tools on your own server for free (jpegtran, optipng, pngout, pngquant, gifsicle, cwebp), or can be 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.

If you need a version of this plugin for API use only, see EWWW Image Optimizer Cloud. It is much more compact as it does not contain any binaries or any mention of the exec() function.

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.

Support

If you need assistance using the plugin, please visit our Support Page. The EWWW Image Optimizer is developed at https://github.com/nosilver4u/ewww-image-optimizer

Bulk Optimize

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.

Optimize Everything Else

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.

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 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 Image Editor

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.

WebP Images

Automatic WebP conversion with Easy IO, 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.

WP-CLI

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.

FooGallery

All images uploaded and cached by FooGallery are automatically optimized. Previous uploads can be optimized by running the Media Library Bulk Optimize. Previously cached images can be optimized by entering the wp-content/uploads/cache/ folder under Folders to Optimize and running a Scan & Optimize from the Bulk Optimize page.

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.

NextCellent Gallery

Features all the same capability as NextGEN, and is the continuation of legacy (1.9.x) NextGEN support.

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.

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.

CDN Support

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/
