Winsite Image Optimizer will compress your images for optimal file-size while keeping its quality (pretty much) intact, using the ImageOptim API (and other processing engines coming up soon).
You can also process all of your old images retroactively using our dedicated tool, found under the Media section.
Currently-implemented Image Processing Services:
<ul>
<li><a href="https://imageoptim.com/api" rel="nofollow ugc">ImageOptim</a> (You’ll need to obtain an <a href="https://im2.io/register" rel="nofollow ugc">API key</a>)</li>
<li>Send your suggestions on our <a href="https://github.com/win-site/winsite-image-optimizer/issues" rel="nofollow ugc">GitHub issue tracker</a>.</li>
</ul>
Warning: This won’t work on localhost in some cases, since some services work in a way that they pull images in from your site. This is why you’ll need a public URL in order to make this work locally. 
You can use a service such as ngrok to achieve that, in conjunction with this filter:
<pre><code>add_filter( 'wsi_siteurl_override', function( $siteurl ) {
 return 'http://ae190611.ngrok.io/path-to-wp-installation/';
} );
</code></pre>
We’d love to recieve contributions / suggestions from you on our <a href="https://github.com/win-site/winsite-image-optimizer/" rel="nofollow ugc">GitHub project</a>.

Winsite Image Optimizer

Better optimization it's so important for websites. This useful plugin work out of the box with minimum attention and maximum optimization.



Work like a charm!

I have been looking for a reliable image compression tool for WordPress for a long time.. Finally found this one that actually does what it should and does it great. Big shout out to the developers!!!



Awesome !

I can't recommend this plugin as it changed lots of file names and duplicated images.

With some regex I managed to get rid of some of its damage, but with large sites this would have been a nightmare

I would say avoid this plugin to be safe, there are better plugins out there for image compressions

Changed all image file names + weird redirects

The plugin worked good and I've been using it for two years. Some of it's functions are basic and it does rename images, which has been a nuisance for me. I had to use another plugin - Media file rename to remove wsi-imageoptim- prefix from filenames (Google uses image filenames for indexing). But there is a saying: you don't look in teeth a horse which was given to you for free. Therefore three stars.
