Réduisez les tailles d’image dans WordPress en incluant NextGEN, GRAND FlAGallery, FooGallery et autres méthodes de compression sans perte de qualité et de conversion de format d’image.
EWWW Image Optimizer est une extension WordPress qui va automatiquement optimiser les images que vous téléversez sur votre blogue. Il peut optimier les images que vous avez déjà téléversées, convertir automatiquement vos fichiers images au format qui produira la taille d’image la plus petite (assurez-vous de lire les avertissements), et optionnellement appliquer une compression avec pertes pour réaliser d'énormes économies pour les images PNG et JPG.
Why use EWWW Image Optimizer?
By default, EWWW Image Optimizer 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.
The tools used for optimization are jpegtran, TinyJPG, JPEGmini, optipng, pngout, pngquant, TinyPNG, and gifsicle. Most of these are freely available except TinyJPG/TinyPNG and JPEGmini. Images are converted using the above tools and one of the following: GMagick, IMagick, or GD.
EWWW Image Optimizer calls optimization utilities directly which is well suited to shared hosting situations where these utilities may already be installed. Pre-compiled binaries/executables are provided for optipng, gifsicle, pngquant, cwebp, and jpegtran. Pngout can be installed with one-click from the settings page. If none of that works, there is a cloud option that will work for any site.
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.

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.
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 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, send an inquiry on the support page.
Site admins can specify any folder within their 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 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.
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 Alternative 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.
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.
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.
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.
Les téléversements vers Amazon S3, Azure Storage, Cloudinary et Dreamspeed CDN sont optimisés. Tous les modes de traction de CDNs comme Cloudflare, KeyCDN, MaxCDN et Sucuri CloudProxy sont également pris en charge.
