Install WP-CLI from, and run 'wp-cli.phar help ewwwio optimize' for more information. 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). WP-CLIĪllows you to run all Bulk Optimization processes from your command line, instead of the web interface. Also works with the WebP option in the Cache Enabler plugin from Ke圜DN. Several methods are available for serving WebP images, including Apache-compatible rewrite rules and our Alternative WebP Rewriting option compatible with caches and CDNs. WebP ImagesĬan generate WebP versions of your images, and enables you to serve even smaller images to supported browsers. Scheduled optimization should not be used for any plugin that uses the built-in WordPress image functions. Additionally, this tool can run on an hourly basis via wp_cron to keep newly uploaded images optimized. The Bulk Scan 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. Site admins can specify any folder within their WordPress folder to be optimized. If you are not sure if a plugin uses WP_Image_Editor, send an inquiry on the support page. 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. Current implementations are GD, Imagick, and Gmagick. WP Image EditorĪll images created by the built-in WP_Image_Editor class will be automatically optimized. The re-optimize links on the Media Library page also force the plugin to ignore the previous optimization status of images. You may also remove individual images from the list, or use the Force optimize option to override the default behavior. On the Bulk Optimize page you can view a list of already optimized images. Skips Previously Optimized ImagesĪll optimized images are stored in the database so that the plugin does not attempt to re-optimize them unless they are modified. Officially supported galleries (GRAND FlaGallery, NextCellent and NextGEN) have their own Bulk Optimize pages. This includes the Media Library, your theme, and a handful of pre-configured folders (see Optimize Everything Else below). Optimize all your images from a single page using the Bulk Scanner. The EWWW Image Optimizer is developed at Bulk Optimize If you need assistance using the plugin, please visit our Support Page. If you need a version of this plugin for API use only, see ESupport If none of that works, there is a cloud option that will work for any site. Images are converted using the above tools and one of the following: GMagick, IMagick, or GD.ĮPngout can be installed with one-click from the settings page. Most of these are freely available except TinyJPG/TinyPNG and JPEGmini. The tools used for optimization are jpegtran, TinyJPG, JPEGmini, optipng, pngout, pngquant, TinyPNG, and gifsicle. 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. The gif2png and jpg2png conversions are also lossless but the png2jpg process is not lossless. While the optimization is technically lossless, you will not be able to properly edit the animation again without performing an -unoptimize operation with gifsicle. Optimize everything With the wp_image_editor class extension, and the ability to specify your own folders for scanning, any image in WordPress can be optimized.īy default, EThe one small exception to this is GIF animations.Root access not needed Pre-compiled binaries are made available to install directly within the WordPress folder, and cloud optimization is provided for those who cannot run the binaries locally.And if that isn't enough, try the powerful TinyPNG option. You can use pngout, optipng, and pngquant in conjunction. With TinyJPG integration, nothing else comes close (requires an API subscription). PNG files take the longest, but you can adjust the settings for your situation. You can optimize hundreds of images in just a few minutes. The plugin can run on your own server, so you don’t have to wait for a third party service to receive, process, and return your images. Optimizing your images can save you hundreds of KB per image, which means significantly less bandwidth usage. Smaller image sizes also means faster backups. This will make your visitors happy, and can increase revenue. Smaller image sizes means faster page loads.
