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. optimizará las imágenes subidas y creadas por cualquier plugin, y tiene integraciones especiales con muchos de los plugins más populares, detallados abajo.

¿Por qué usar EWWW Image Optimizer?

  1. Sin limitaciones de velocidad y sin limitaciones de tamaño de archivo. Gracias la Optimización automática en segundo plano y la optimización paralela opcional, elimina los retrasos en las subidas y vuelve a hacer lo que te gusta.
  2. Funcionamiento sencillo con optimización perfecta de píxeles utilizando herramientas líderes de la industria y el renderizado progresivo.
  3. Alto equilibrio, ya que te ofrecemos la mejor relación de compresión/calidad disponible con nuestras opciones con pérdida para archivos JPG, PNG y PDF.
  4. Dirección adaptable con opciones de conversión inteligente para obtener el formato de imagen más adecuado (JPG, PNG o GIF).
  5. Alojamiento gratuito El plugin principal es gratuito y siempre lo será. Además, si eliges la API, nunca pagarás por una imagen que no podamos comprimir, nunca se te facturará por un mes si no usas la API, y los créditos de prepago nunca caducan. Además, consigue la generación de imágenes WebP sin costes adicionales: cualquier JPG o PNG se puede convertir al formato de imagen de próxima generación de Google.
  6. Cobertura completa: no se dejan imágenes sin procesar, optimízalo todo en su sitio, más allá de la biblioteca multimedia de WordPress.
  7. La seguridad primero: todas las conexiones están protegidas con un cifrado SSL de alto nivel.
  8. Asistencia de viaje: el soporte de primer nivel está en nuestro ADN. Si bien los clientes con API tienen la máxima prioridad, respondemos cada pregunta de soporte con cuidado.
  9. Paquetes de repuesto: copias de seguridad gratuitas que almacenan las imágenes originales durante 30 días.

Las imágenes se pueden optimizar utilizando herramientas en tu propio servidor de forma gratuita (jpegtran, optipng, pngout, pngquant, gifsicle, cwebp), o pueden optimizarse a través de servidores especializados que utilizan las mejores herramientas disponibles en modo sin pérdida o con pérdida. Nuestra compresión con pérdida utiliza algoritmos únicos para obtener la máxima compresión sin perder la apariencia visual. Tus imágenes se pueden convertir al formato de archivo más adecuado utilizando ciertas opciones. Si utilizas el API de EWWW I.O. permitirás que el plugin funcione en cualquier plataforma de alojamiento, y también puede ser conveniente si no puedes o no deseas utilizar la función exec() en tu servidor, o si prefieres descargar las demandas de recursos de de la optimización.

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().

Automatic Resizing

With ExactDN support, images will be automatically resized to fit the page and device size. ExactDN also enables basic retina support and automatic lossless compression.

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

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.

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

Uploads to Amazon S3, Azure Storage, Cloudinary, and DreamSpeed CDN are optimized. All pull mode CDNs like Cloudflare, KeyCDN, MaxCDN, and Sucuri CloudProxy are also supported.

WPML Compatible

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

  • 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. Activa el plugin desde el menú ‘Plugins’ de WordPress.
  3. Ensure jpegtran, optipng, pngout and gifsicle are installed on your Linux server (basic installation instructions are below if they are not). You will receive a warning when you activate the plugin if they are not present. This message will go away once you have them installed.
  4. 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.
  5. If the automatic install did not work, find the appropriate binaries for your system in the ewww-image-optimizer plugin folder, copy them to wp-content/ewww/ and remove the OS “tag” (like -linux or -fbsd). No renaming is necessary on Windows, just copy the .exe files to the wp-content/ewww folder. IMPORTANT: Do not symlink or modify the binaries in any way, or they will not pass the security checks. If you transfer files via FTP, be sure to transfer in binary mode, not ascii or text.
  6. 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/
  7. Recommended Visit the settings page to enable/disable specific tools and turn on advanced optimization features.
  8. Done!

If these steps do not work, additional documentation is available at http://docs.ewww.io. If you need further assistance using the plugin, please visit our Support Page. The forums are community supported only.

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

Try this for starters: http://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): http://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 TinyJPG and JPEGmini 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: http://docs.ewww.io/article/12-jpq-quality-and-wordpress

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

If it doesn’t seem to work at all, check for javascript problems using the developer console in Firefox or Chrome. If it is not working just on some images, you may need to increase the setting max_execution_time in your php.ini file. There are also other timeouts with Apache, and possibly other limitations of your webhost. If you’ve tried everything else, the last thing to look for is large PNG files. In my tests on a shared hosting setup, “large” is anything over 300 KB. You can first try decreasing the PNG optimization level in the settings. If that doesn’t work, perhaps you ought to convert that PNG to JPG or set a max PNG optimization size. Screenshots are often done as PNG files, but that is a poor choice for anything with photographic elements.

What are the supported operating systems?

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

How are JPGs optimized?

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. Lossy optimization is done using the outstanding TinyJPG and JPEGmini utilities.

How are PNGs optimized?

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 on the settings page. Optipng is an automated derivative of pngcrush, which is another widely used png optimization utility. EWWW I.O. Cloud uses TinyPNG for 10% better lossy compression than standalone pngquant.

How are GIFs optimized?

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 these resources:
https://developers.google.com/speed/docs/insights/OptimizeImages
http://developer.yahoo.com/performance/rules.html#opt_images

Pngout, TinyJPG/TinyPNG, JPEGmini, and Pngquant were recommended by EWWW IO users. Pngout (usually) optimizes better than Optipng, and best when they are used together. TinyJPG is the best lossy compression tool that I have found for JPG images. Pngquant is an excellent lossy optimizer for PNGs, and is one of the tools used by TinyPNG.

Reseñas

10 star plugin!

Life saver! It’s the best WordPress optimization plugin I’ve used.

I was having serious trouble with the gallery plugin I was using, which generated thumbnails heavier than the original images. With EWWW I was able to target these thumbnails and optimize them, something other image optimizing plugins could not do.

With EWW I’m not getting ANY image optimization warnings from PageSpeed any more.

Many thanks.

Support service is great!

In spite of New Year holidays, thank you very much for your answer from support service with email.

I inquired Mr. Shane Bishop while feeling uneasiness to degrees of differences about “Conscientious and Kindness” between Japanese support service and another support service. But I could get the answer polite enough from your support service.
So, I could get a peace of mind.

The support service is equally as wonderful as this plugin is!

Thank you very much for your help.

ewww.io and ExactDN (CDN) is awesome

What can I say: My sites images are smaller, my site is faster and with the new ewww.io ExactDN (CDN) my site is way faster.

Here are my blog posts sowing the ewww.io image optimizer and Exact CDN from EWWW.

Optimize images automatically in WordPress
https://fearby.com/optimize-images-automatically-in-wordpress-with-ewww-image-optimizer-plugin/

Speeding up WordPress with the ewww.io ExactDN CDN and Image Compression Plugin
https://fearby.com/article/speeding-up-wordpress-with-the-ewww-io-exactdn-cdn-and-image-compression-plugin/

and my steps in using ewww.io in Speeding up WordPress https://fearby.com/article/improving-the-speed-of-wordpress/

Really slow

Ever since the up-date and new feature of incorporating a CDN, the speed to convert images from your blog is terrible slow. You have to wait like 3 minutes now for every image you upload in a wordpress post. Ugh. Thinking about dropping this plugin for a few months just until author works out this problem.

Perfect! Does what it promises, even on shared hosting.

I recently got comments about a larger gallery on my website that it has a quite bad test result on GTMetrix and the overall loading time was not very fast as well. Then I learned about “optimized images” and checked out different plugins.

EWWW Image Optimizer turned out to be the best for me – free version available, no special tools required (it even works, if only GD is available on shared hosts, even though results may be a bit better with ImageMagick etc.) and the results are impressive! Bulk compression of several thousand images (including thumbnails etc.) worked without any problem at all.

After using it on different sites (on my own server and also some friends shared hosts, whom I help with their WordPress sites) the total download size gallery previews was nearly reduced by 30-50% and the result at GTmetrix improved from “F” to “A” or “B” for PageSpeed :-).

So – yes, I can recommend it – good work!

One of the first plugins I install on every site. 5/5

I’ve been using free EWWW for several years on more than a dozen sites – it’s a set-and-forget plugin that works flawlessly. I have no idea why some people rate this so low – have a read of the 1-star reviews to see if you can understand why !?

A few days back, I received a PHP error message in my dashboard. The plugin author helped straight away over several emails, despite it being nothing to do with the plugin as it turned out to be a server config error on my side! Above and beyond 5/5 keep up the good work.

Support ? Read this. See here for an excellent technical review and comparison to SMUSH. Be sure to checkout the author’s other excellent plugin Imsanity for bulk image resize.
