It can optimize the images that you have already uploaded, convert your images automatically to the file format that will produce the smallest image size (make sure you read the WARNINGS), and optionally apply lossy compression to achieve huge savings for PNG and JPG images. **Why use EWWW Image Optimizer?** 1. **Your pages will load faster.** Smaller image sizes means faster page loads. This will make your visitors happy, and can increase revenue. 1. **Faster backups.** Smaller image sizes also means faster backups. 1. **Less bandwidth usage.** Optimizing your images can save you hundreds of KB per image, which means significantly less bandwidth usage. 1. **Super fast.** 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. You can optimize hundreds of images in just a few minutes. PNG files take the longest, but you can adjust the settings for your situation. 1. **Best JPG optimization.** With TinyJPG integration, nothing else comes close (requires an API subscription). 1. **Best PNG optimization.** You can use pngout, optipng, and pngquant in conjunction. And if that isn't enough, try the lossy PNG option powered by TinyPNG. 1. **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. 1. **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. 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](http://jpegclub.org/jpegtran/), [TinyJPG](http://www.tinyjpg.com), [JPEGmini](http://www.jpegmini.com), [optipng](http://optipng.sourceforge.net/), [pngout](http://advsys.net/ken/utils.htm), [pngquant](http://pngquant.org/), [TinyPNG](http://www.tinypng.com), and [gifsicle](http://www.lcdf.org/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, GD or 'convert' (ImageMagick). 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 cloud use only, see [EWWW Image Optimizer Cloud](https://wordpress.org/plugins/ewww-image-optimizer-cloud/). It is much more compact as it does not contain any binaries or any mention of the exec() function. = Support = If you need assistance using the plugin, please visit our [Support Page](https://ewww.io/contact-us/). The forums are community supported only. The EWWW Image Optimizer is developed at https://github.com/nosilver4u/ewww-image-optimizer = Bulk Optimize = There are two functions on the Bulk Optimize page. One is to optimize all images in the Media Library. The Scan and Optimize is for everything else. Officially supported galleries (GRAND FlaGallery and NextGEN) have their own Bulk Optimize pages. = 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 additionally choose to 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, post your question in the support forums. = Optimize Everything Else = Site admins can specify any folder within their wordpress folder to be optimized. The 'Scan and Optimize' option 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. = 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. = 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. = Translations = Huge thanks to all our translators: Bulgarian translation by Ivan Arnaudov Dutch translation by Ludo Rubben French translation by Bruno Tritsch, Nicolas Juen, Philippe Dupuit, Jean-Baptiste Gourdin, Dominique Goethals, Mickaël Chapusot, and Guillaume Thibord German translation by Christian Herrmann and Ralf Platschi Italian translation by Umberto Moroni, Alexander Gevak and Fabrizio Balestrieri Polish translation by Grzegorz Janoszka Portuguese (Brazil) translation by Pedro Marcelo de Sá Alves and Celso Azevedo Portuguese (Portugal) translation by Celso Azevedo Romanian translation by Iosif Kadar of MediasInfo.ro Russian translation by Elvis of turkenichev.ru, Roman Sobol, and Vitaliy Ralle Spanish translation by Manuel Ballesta Ruiz and Adrián López Galera Swedish translation by Alexander Widén Turkish translation by sfatih Ukrainian translation by Roman Sobol Full contributors list is at https://translate.wordpress.org/projects/wp-plugins/ewww-image-optimizer/contributors If you would like to help translate this plugin (new or existing translations), you can do so here: https://translate.wordpress.org/projects/wp-plugins/ewww-image-optimizer To receive updates when new strings are available for translation, you can signup here: https://ewww.io/register/ == Installation == 1. Upload the 'ewww-image-optimizer' plugin to your '/wp-content/plugins/' directory. 1. Activate the plugin through the 'Plugins' menu in WordPress. 1. 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. 1. 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. 1. 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. 1. 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/ 1. *Recommended* Visit the settings page to enable/disable specific tools and turn on advanced optimization features. 1. Done! If these steps do not work, more detailed instructions are available below the video tutorials. If you need further assistance using the plugin, please visit our [Support Page](https://ewww.io/contact-us/). The forums are community supported only. At the bottom of this page, you will find a list of known working webhosts. If you have any contributions or corrections to these lists, please contact me via the form at https://ewww.io/contact-us/ EWWW IO - Getting Started [youtube https://www.youtube.com/watch?v=bwn53mhFdTs] EWWW IO - Advanced Settings [youtube https://www.youtube.com/watch?v=kifGIs5Lx2U] EWWW IO - Converting Images [youtube https://www.youtube.com/watch?v=xAGtdv3vrYg] EWWW IO - WebP [youtube https://www.youtube.com/watch?v=OeYJgTy3D94] EWWW IO - Cloud API Walkthrough [youtube https://www.youtube.com/watch?v=U78FFkM582E] Using EWWW IO: [youtube https://www.youtube.com/watch?v=uELM25v-qgU] = Installing pngout = Pngout is not enabled by default because it is resource intensive. Optipng is the preferred PNG optimizer if you have resource (CPU) constraints. Pngout is also not open-source for those who care about such things, but the command-line version is free. 1. Go to the settings page. 1. Uncheck the option to disable pngout and Save your settings. 1. Click the Automatic link in the Plugin Status area to install pngout for your server, and the plugin will download the pngout archive, unpack it, and install the appropriate version for your server. 1. Adjust the pngout level according to your needs. Level 0 gives the best results, but can take up to a minute or more on a single image. To manually install pngout: 1. Click the Manual link in the Plugin Status. 1. Download the version of pngout that matches your webserver (NOT your desktop/laptop). Always use the -static downloads for Linux and FreeBSD. If you don't know if you have a linux server, or Mac, or whether it is 32-bit vs 64-bit, ask your webhost, or turn on debugging and post the debug information in the forums with your request for assistance. 1. If you have Windows on your personal computer, you may need to install 7-zip or something similar to extract the .tar.gz files. Linux and Mac OS X systems should have built-in support for gzipped files. 1. For Linux and FreeBSD pngout downloads, you will see an i686 folder and x86_64. The first is for 32-bit the latter is for 64-bit. Upload the pngout-static file (pngout for Mac, pngout.exe for Windows) to the wp-content/ewww/ folder on your web server. 1. Make sure the permissions are set correctly. It is recommended to use 755 or rwxr-xr-x, which is read, write, execute for the owner, read/execute for the group, and read/execute for everyone else. 1. If pngout still is not working, you can download older versions, but do not go further back than the 20130221 release: http://static.jonof.id.au/dl/kenutils/ = Installing (Compiling) other tools = https://ewww.io/2014/12/06/the-plugin-says-im-missing-something/ = Webhosts = In general, these lists only apply to shared hosting services.

What do I do? = Try this for starters: https://ewww.io/2014/12/05/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://ewww.io/2014/12/06/the-plugin-says-im-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 Advanced tab. = Can I lower the compression setting for JPGs to save more space? = The lossy optimization using the EWWW IO Cloud service will determine the ideal quality setting and save even more space. You cannot manually set the quality with this plugin, but Imsanity (and many others) will do that if you really want to. But you should REALLY try EWWW IO Cloud first. = 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 (8 and 9), and Solaris (v10). The cloud service will run 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: http://developer.yahoo.com/performance/rules.html#opt_images https://developers.google.com/speed/docs/best-practices/payload#CompressImages https://developers.google.com/speed/docs/insights/OptimizeImages 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. == Screenshots == 1. Plugin settings page. 2. Additional optimize column added to media listing. You can see your savings, manually optimize individual images, and restore originals (converted only). 3. 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. == Changelog == * feature requests are sticky at the top of the support forums, vote for the ones you like: https://wordpress.org/support/plugin/ewww-image-optimizer * If you would like to help translate this plugin in your language, get started here: https://translate.wordpress.org/projects/wp-plugins/ewww-image-optimizer/ = 3.1.2 = * added: ability to disable background optimization via ewww_image_optimizer_background_optimization filter * changed: scan and optimize rewritten to store images in batches, with auto-retry for very large sites * changed: folders to optimize validator will attempt to fix relative paths and urls * changed: conversion operations are not run in background, override with ewww_image_optimizer_defer_conversion filter * changed: reverted Alt WebP support for lazy load, as it does not work consistently * changed: cache query results for excessive reoptimization up to an hour * fixed: ensure disabled resizes are not optimized during Enable Media Replace uploader * fixed: images were not optimized after editing with Post Thumbnail Editor * fixed: bulk operation handles attachment ID as a string instead of an integer * fixed: bulk optimizing a single image displays no results * fixed: bulk optimizing images with corrupted metadata does not result in a repair operation * fixed: image scanner skips optimized metaslider images even if they have changed * fixed: scan and optimize includes file types that are disabled = 3.1.1 = * fixed: exec() notice surpressed when it should not be = 3.1.0 = * added: warning when excessive re-optimizations have been detected * added: Alt WebP supports lazy loading in Hueman theme * added: Alt WebP supports Lazy Load plugin and Cherry Lazy modifications * added: Alt WebP supports BJ Lazy Load plugin * added: Alt WebP supports Retina Lazysizes * added: ability to defer resizing of uploaded image using ewww_image_optimizer_defer_resizing filter, "other" dimensions will apply regardless of upload method * changed: wp_image_editor integration does not use background optimization, reverting to inline processing, holler if you want it back * changed: all scripts have proper version numbers to avoid caching issues * changed: inline webp script moved to head element to work better with lazy loading * changed: optimized Alt WebP code for smaller size = 3.0.2 = * fixed: fatal error running empty() on a constant in PHP less than 5.5 = 3.0.0 = * fixed: resizes not checked for existence before calling parallel/async optimization, causing the process to stall * fixed: background optimization disabled when settings are saved * fixed: regression in db upgrade function throws warning on plugin upgrade * fixed: alt webp breaks Slider Revolution's lazyload when dummy.png.webp exists * fixed: background optimization for nextcellent was incomplete * fixed: notices under Manage Gallery for nextcellent when tool constants were not defined * changed: one-click actions in Media Library don't require reload, now possible to optimize several images at the same time * changed: API quota check no longer requires a verification on every attempt * changed: webp settings moved to separate tab * added: forced webp mode, to generate webp for every image, regardless of final filesize * added: in forced webp mode, must specify allowed url patterns for rewriting == Upgrade Notice == = 2.9.0 = * changed: JPG quality setting applies to conversion AND image editing (but not regular optimization), so that you can override the WP default of 82 (it is NOT recommended to increase the quality) * added: parallel optimization for Media uploads (original and resizes are done concurrently), turn off under Advanced if it affects site performance = 2.8.4 = * security fix: remote command execution, please update immediately = 2.8.1 = * KeyCDN added support for WebP images generated by EWWW I.O. into the Cache Enabler plugin.
