How to compress images and PDF with the WordPress plugin
Install the Image and PDF Compression Plugin
Download the plugin from the WordPress plugin directory:
The plugin can be installed through FTP by uploading unzipped files in the wp-content/plugin folder or using the standard WordPress installer. Then activate the plugin.
Once the plugin is installed and activated you can register a free trial account or use and existing account, through the menu Settings > ImageRecycle. Note that once your account is created or connected, the API key will be saved automatically and you can start using the service.
Click on one of the button "Create a trial account" to register a new account.
If you already have an account, just login, your API will be filled automatically. Plus if you have some sub accounts registered on your ImageRecycle account, you can pick up one on a next screen.
Authenticate with your API key to apply media compression quota
After being logged in from the menu My account > API and quota (on ImageRecycle website) you can get or generate an API Key. For the main account the key is automatically generated.
Then copy-paste the API Key and API Secret in your WordPress plugin configuration.
Once your API key and secret is added, you'll get an account resume in the Settings > ImageRecycle plugin view.
Using sub-accounts to optimize media for your clients
Sub-account creation button with dedicated API key are right bellow. Subaccount number is not limited and each sub-account have a dedicated quota you can define (perfect for multiple clients websites). Once you use the sub-account API key, the image quota will be deducted from this sub-account quota.
Optimize existing & new images and PDF
With the WordPress plugin you have the possibility to bulk optimize all existing images or new images right after upload. To access to the plugin optimization interface click on: Media > ImageRecycle.
New images are automatically optimized on upload if you've set the plugin to optimize this file format.
You can optimize already existing images and PDF one by one or use the "Optimize all" button to apply a compression on several elements. You can also revert to original if needed during the backup storage time (1 month).
After optimization or during the restoration, images will be replaced on your server automatically.
The bulk optimization will run the process on all your content in background. It means that you can work with WordPress during this time and you'll get Emailed once it's done.
Now, all media will be placed in queue and you'll get an estimation of the time remaining.
Use filtering and sorting to find your media
The plugin includes some ways to find your media, the latest uploaded, the heaviest... You can use the top filtering tools to filter by status, file type or dates.
Or click on the column titles to order your media by File name, size, optimization status
Images auto resizing before optimization
You have option to activate an auto image resizing. It means that all the images stored on your server will have the max size specified in this option.
Select the server folders to optimize your WordPress media
In the global configuration you can select which folder you want to optimize. If you're using 3rd party plugins that store images or pdf in root folder you can force optimization for example. If you uncheck a folder, optimization won't be applied in the folder.
Image optimization quality and PDF compression activation
Quality options can be defined per content type. For example, if you want to disable PDF optimization to keep original quality for print, you can select No compression as PDF compression parameter.
Images optimization exclusion by weight
You have advanced exclusion parameter that let you exclude/include specified server folders from optimization.This parameter is very useful for third party plugins or themes that add their own folders. You can also define a range of file size for your optimization.
A good setup here avoid applying compression on unneeded images, ie. the content not displayed on public side of your WordPress website.
