Optimisation de masse
Optimize images, all from a single page. This includes the Media Library, your theme, and a handful of pre-configured folders (see Optimize Everything Else below). GRAND FlaGallery, NextCellent and NextGEN have their own Bulk Optimize pages.
Optimiser tout le reste
Configure any folder within your WordPress install to optimize images. The Bulk Optimizer will compress 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. You can also use Scheduled optimization or run the optimizer from WP-CLI if that’s more your thing.
Compatibilité de l’extension
EWWW Image Optimizer has been tested with thousands of plugins and themes, here are just a few of the most common ones: BuddyPress (Activity Plus add-on too), Cloudinary, Easy Watermark, FileBird, FooGallery, GD bbPress Attachments, GRAND FlAGallery, Gmedia Photo Gallery, MediaPress, Meta Slider, Microsoft Azure Storage, MyArcadePlugin, NextGEN Gallery, Regenerate Thumbnails, Weglot, WP Offload Media, WPML, WP Retina 2x, WP RSS Aggregator, WP Symposium, and more…
Images WebP
If you want simple, get automatic WebP conversion with Easy IO, and be done with it! Otherwise, you can generate WebP versions of unlimited images with the Bulk Optimizer. Deliver them to supported browsers with Apache-style rewrite rules, JS WebP Rewriting, or Picture WebP Rewriting. EWWW Image Optimizer even works with the WebP option in the Cache Enabler plugin from KeyCDN.
Images AVIF
La conversion AVIF est intégrée au CDN Easy IO. Une fois que votre site est configuré avec Easy IO, modifiez les réglages du site pour activer AVIF, et c’est terminé !
WP-CLI
Allows you to run all batch image processes from the command line, instead of the web interface. Optimize images even faster, 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.
Support CDN
WP Offload Media is the officially supported (and recommended) plugin for uploads to Amazon S3, Digital Ocean Spaces, and Google Cloud Storage. Check our compatibility list for details on other plugins. All pull mode CDNs like Cloudflare, KeyCDN, Bunny CDN and Sucuri work automatically, but you will need to purge the CDN cache after you optimize images with bulk optimization.

FAQ
-
Est-ce que l’extension retire les données EXIF et/ou IPTC ?
-
EWWW Image Optimizer will remove metadata by default, but if you need to keep the EXIF/IPTC data for copyright purposes, you can disable the Remove Metadata option.
EXIF data does not impact SEO, and it is recommended by Google (and just about everyone else) to remove EXIF data. -
Google Pagespeed dit que mes images doivent être compressées ou redimensionnées, mais j’ai déjà optimisé toutes mes images. Que puis-je faire ?

-
L’extension remplace-t-elle les images existantes ?
-
Oui, mais uniquement si la version optimisée est plus petite. L’extension ne crée jamais d’image plus grande.
-
Puis-je diminuer le réglage de compression pour les fichiers JPEG pour économiser plus d’espace ?
-
Notre compression premium peut déterminer le réglage de qualité idéal et vous donner les meilleurs résultats, mais vous pouvez également ajuster la qualité par défaut pour la conversion et le redimensionnement. Lire la suite…
