EWWW Image Optimizer

説明

EWWW Image Optimizer は画像を最適化することでページのロード速度を向上させます。ロード速度を向上させることで検索結果のランキングで上位に表示されたり、売上が向上したりします。またサーバーのストレージと転送量を下げることも出来ます。EWWW I.O. の自動圧縮が機能していると、新しくアップロードした画像や既にアップロードしてある画像も適切なファイルフォーマットで圧縮します。画素数重視の圧縮か高い圧縮 (視覚的に同一のイメージになります) にするかを選択することが出来ます。

EWWW I.O. はアップロードされた画像やプラグインの画像を最適化し、人気のプラグインとの連携機能も備えています。詳細は以下です。

EWWW Image Optimizer を使う理由

  1. 速度制限なし & ファイルサイズ制限なし。バックグラウンドでの自動最適化と並行最適化を使ってアップロードの遅延を解消し、他の好きなことに戻りましょう。
  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. Additionally, if you choose the API, you never pay for an image we can’t compress, you are never billed for a month you do not use the API, and pre-paid credits never expire. Plus, get WebP image generation at no extra cost: any JPG or PNG can be converted to Google’s next-generation image format.
  6. Comprehensive Coverage: no image gets left behind, optimize everything on your site, beyond just the WordPress Media Library.
  7. 安全第一: すべての通信は最高レベルの SSL 接続で暗号化されています。
  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.

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.

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 compression.

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 画像

One-click WebP with ExactDN and JS WebP Rewriting. 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.

CDN をサポート

WP Offload Media is the officially supported (and recommended) plugin for uploads to Amazon S3 and Digital Ocean Spaces. We also support the Azure Storage and Cloudinary plugins. All pull mode CDNs like Cloudflare, KeyCDN, MaxCDN, and Sucuri CloudProxy work automatically, but will require you to purge the cache after a bulk optimization.

WPML Compatible

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

スクリーンショット

  • Plugin settings page.
  • 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.

インストール

  1. Upload the “ewww-image-optimizer” plugin to your /wp-content/plugins/ directory.
  2. 「プラグイン」メニューからプラグインを有効化します。
  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. 完了しました。

FAQ

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?

はい、ただし、最適化されたバージョンが小さい場合に限ります。 プラグインは決してより大きい画像を作成することはないでしょう。

Can I resize my images with this plugin?

リサイズタブより設定できます。

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.

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.

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 using the Overrides. Optipng is an automated derivative of pngcrush, which is another widely used png optimization utility.

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

評価

Super expensive

The plugin does what it claims, but it's highly expensive if you have many images. I don't recommend on sites with a lot of images. It gets costly.

Avoid

Minimal speed gains. Unable to delete. Support non-existent. This plugin has been nothing but a pain.

You won’t regret this purchase

Just an awesome module which is easy to use and configure. This module (with the ExactDN service) boosted my Google PageSpeed score by around 15%. I encountered a slight problem, I emailed support and Shane Bishop (support analyst) worked tirelessly until my problem was fixed. Amazing product and after sales support, you won't regret this purchase.

Great plugin

Easy and comprehensive point and click settings to configure compression and webp rewriting for supporting browsers. Also has WP-CLI option for developers – particularly useful when you need to run optimisations on a large set of preexisting or regenerated images. The cost per image over the free amount is very affordable.

Developer abuses image sizes

I'm unhappy with the solution, it does not offer proper inclusion for mass optimization and you always have to optimize the images you don't need. E.g. you only want to optimize the homepage images, and there is no way to select them. Also, there is no way to select only original images, even if you deselect all thumbnails it still finds some 3-4 other sizes which you cannot exclude from mass optimization. Per image pricing is too greedy for that, considering you are using your own server resources. Plugin has very bad UX
