WordPress Plugins
Are there wordpress image compression plugins? Yes tons of them, but most of them have limitations and confusing pricing structures. We can only recommend 1 wordpress plugin for image compression.
Imsanity
The reason we recommend this plugin is because it doesn’t have any limitations and is 100% free. We use this plugin on most of our client websites. One of the best tools is the Bulk-resize feature. This feature is great when you need to bulk compress a bunch of existing images on a website.
This plugin will also automatically resize images on upload. This works great if a client is uploading large images, it will resize them to a defined width or height from your Imsanity Settings.
Another great feature with Imsanity is the ability to control or disable the default WordPress JPG image compression.
Below is more information on this default WordPress functionality.

How to Stop WordPress From Compressing Images
You might not be aware of this, but WordPress is compressing all your images uploaded through the media library by default. Don’t worry, most people have no idea that WordPress has been doing this for years. But you might have noticed your images look a little different and don’t have matching file sizes when you upload them through media library.
By default WordPress is compressing your images to 82% quality. This means you might be running a double compression on your images and getting bad results. We highly recommend disabling this option if you plan to optimize your images manually or automatically.
If you don’t want to use another plugin to disable this WordPress function, the easiest thing to do is to add the following code to your function.php theme file:
add_filter(‘jpeg_quality’, function($arg){return 100;});
The ‘return’ value of 100 ensures that WordPress will keep the original quality of the image.

When developing a website, it’s important to compress your images manually as you develop each page. Yes, this will require 1 additional step in your workflow, but it’s now a best practice to include this into your workflow because it will save you time in the long term.
There’s some great online tools like TinyJPG that will help compress your images, these services normally don’t allow you to make advanced changes to their compression settings.
Good news! There’s a great new open source online tool that Google has just released. It’s called Squoosh, we took this tool for a spin when it was released and we are now using it in our workflow for compressing our images while we are developing our websites.
Squoosh uses several “best-in-class codecs” for compressing your images in your browser.
We created a video on how to use Squoosh:
As you can see Squoosh is a great free tool! We think the real time preview is the coolest feature.
