EWWW Image Optimizer

Descripción

EWWW Image Optimizer aumentará la velocidad de tus páginas mediante la optimización de imágenes. El aumento de la velocidad de las páginas puede conseguir mejores puestos en los motores de búsqueda y mejorar las tasas de conversión (aumento de ventas y suscripciones). También te ahorrará espacio de almacenamiento y ancho de banda. EWWW Image Optimizer no solo optimiza automáticamente las imágenes nuevas que subas, sino que también puede optimizar todas las imágenes subidas previamente y, opcionalmente, convertirlas al mejor formato de archivo. Puedes elegir la compresión perfecta de píxeles u opciones de alta compresión sin pérdidas visuales de calidad.

EWWW I.O. will optimize images uploaded and created by any plugin, and features special integrations with many popular plugins, detailed below.

¿Por qué usar 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.

Si necesitas una versión de este plugin solo para API, consulta EWWW Image Optimizer Cloud. Es mucho más compacto ya que no contiene archivos binarios ni menciones de la función exec().

Todo automático

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.

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.

Imágenes WebP

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.

Soporte CDN

WP Offload Media es el plugin oficialmente compatible (y recomendado) para cargas en Amazon S3 y Digital Ocean Spaces. También admitimos los complementos Azure Storage y Cloudinary. Todos los CDN en modo pull como Cloudflare, KeyCDN, MaxCDN y Sucuri CloudProxy funcionan automáticamente, pero requerirán que purgue el caché después de una optimización masiva.

Compatible con WPML

Tested regularly to ensure compatibility with multilingual sites. Learn more at https://wpml.org/plugin/ewww-image-optimizer/

Capturas

  • Página de ajustes del plugin.
  • Additional optimize column added to media listing. You can see your savings, manually optimize individual images, and restore originals (converted only).
  • Bulk optimization page. You can optimize all your images at once and resume a previous bulk optimization. This is very useful for existing blogs that have lots of images.

Instalación

  1. Upload the “ewww-image-optimizer” plugin to your /wp-content/plugins/ directory.
  2. Active el plugin a través del menú ‘Plugins’ en WordPress
  3. The plugin will attempt to install jpegtran, optipng, and gifsicle automatically for you. This requires that the wp-content folder is writable by the user running the web server.
  4. If the binaries don’t run locally, you can sign up for the EWWW IO cloud service to run them via our optimization servers: https://ewww.io/plans/
  5. Recommended Visit the settings page to enable/disable specific tools and turn on advanced optimization features.
  6. ¡Listo!

If these steps do not work, additional documentation is available at https://docs.ewww.io/article/6-the-plugin-says-i-m-missing-something. If you need further assistance using the plugin, please visit our Support Page.

Preguntas frecuentes

Google Pagespeed says my images need compressing or resizing, but I already optimized all my images. What do I do?

Try this for starters: https://docs.ewww.io/article/5-pagespeed-says-my-images-need-more-work

The plugin complains that I’m missing something, what do I do?

This article will walk you through installing the required tools (and the alternatives if installation does not work): https://docs.ewww.io/article/6-the-plugin-says-i-m-missing-something

Does the plugin replace existing images?

Yes, but only if the optimized version is smaller. The plugin should NEVER create a larger image.

Can I resize my images with this plugin?

Yes, you can, set it up on the Resize tab.

Can I lower the compression setting for JPGs to save more space?

The lossy JPG optimization using the API will determine the ideal quality setting and give you the best results, but you can also adjust the default quality for conversion and resizing. More information: https://docs.ewww.io/article/12-jpq-quality-and-wordpress

The bulk optimizer doesn’t seem to be working, what can I do?

See https://docs.ewww.io/article/39-bulk-optimizer-failure for full troubleshooting instructions.

¿Cuáles son los sistemas operativos soportados?

I’ve tested it on Windows (with Apache), Linux, Mac OSX, FreeBSD 9, and Solaris (v10). The cloud API will work on any OS.

¿Cómo se optimizan los JPG?

Lossless optimization is done with the command jpegtran -copy all -optimize -progressive -outfile optimized-file original-file. Optionally, the -copy switch gets the ‘none’ parameter if you choose to strip metadata from your JPGs on the options page.

¿Cómo se optimizan los PNG?

There are three parts (and all are optional). First, using the command pngquant original-file, then using the commands pngout-static -s2 original-file and optipng -o2 original-file. You can adjust the optimization levels for both tools using the Overrides. Optipng is an automated derivative of pngcrush, which is another widely used png optimization utility.

¿Cómo se optimizan los GIFs?

Using the command gifsicle -b -O3 –careful original file. This is particularly useful for animated GIFs, and can also streamline your color palette. That said, if your GIF is not animated, you should strongly consider converting it to a PNG. PNG files are almost always smaller, they just don’t do animations. The following command would do this for you on a Linux system with imagemagick: convert somefile.gif somefile.png

I want to know more about image optimization, and why you chose these options/tools.

That’s not a question, but since I made it up, I’ll answer it. See this resource:

Reseñas

27 de febrero de 2020
Every other "free" image optimization plugin I have tried to use turns out to not be so free when you actually try to convert your images. They all want you to process your images on their server so they can charge you for that privilege. Or they hide some essential feature in the "premium" tier to make you pay through the nose, after roping you in with the promise of free image conversion. Or they limit the amount of images that you can process for free to a ridiculously low number. Not so with EWWW Image Optimizer. While they do offer a subscription-based option which is required for some additional, non-essential features, this plugin is capable of doing the whole enchilada on your own server and at absolutely no cost. You don't have to sign up for any external accounts, and there are no limitations on quantity of images it will process on your own server. If you are just looking to compress all of your images while retaining their quality, and all without paying a cent, this is the plugin you are looking for. I have used it on dozens of sites with excellent results every single time.

it's very simple to use and make my site much faster :). I recommend this plugin for everyone who wants to deal with optimization
