Uno de los fundamentales
By , for WP 4.0.1

Es un plugin fundamental para mi, lo instalo en cada nueva web que creo con wordpress, permite optimizar el rendimiento de nuestros sitios al no sobrecargar de pesadas imagenes nuestro contenido.
Lo recomiendo a todo el que haga uso de imagenes por mas minima cantidad que estas sean.

Use to work great but not anymore
By , for WP 4.0

Use to work; been using it for a few years then it started not allowing me to upload more than one image at a time . . . thought bad connection . . . overloaded server . . . no big.
But it continued to the point of not even being able to create a post because I could not upload any image without trying it a bunch of times.
The other day . . . I wasted almost an entire day (8 hours) just trying all the troubleshooting things I found on the web and forums and nothing worked.
Then I came across a post about "Yahoo" handed the program off to WPMUdev and they thought it was going to be so . . . much better now.

Well . . . it's not so much better; it completely sucks.

I understand . . . it's free . . . but I don't think a lot of people understand what it is doing . . . it is processing data "NOT" on my server but theirs . . . that means resources . . . and how much resources can anyone devote to something that is FREE . . . at some point there is going to be a bottle neck.

Looking for a new solution now

UPDATE-Had to uninstall-All good Now
By , for WP 3.9.2

I had hastily posted below without giving this plugin, or its creators the benefit of the doubt. My bad. I've since gone back and reinstalled and successfully used this to help lower some of my overhead from images.

Rating updated :)


hung while doing bulk run of only 112 images. Ran again then killed my site. Had to disable plugin via FTP. Reading through a bunch of the support forums didn't prove much help.

Great Plugin!
By , for WP 4.0

Saves me around 5 - 10% from each image.

In combination with the Imsanity plugin this is a must have!

Really good stuff
By , for WP 4.0

I have been using it for few hours, works great with wordpress 4.0. I believe that this will impact the efficiency of my site and I will be looking forward for future releases.

Some cool stuff that I would love to see in the future are bulk smush all images from the site, I have about 278 pages and I can only go one by one, I guess most of the new users would agree on this one with me :) Or perhaps be able to use the gallery view rather than the list view but thats wp limitation.

thanks for the awesome plugin, was reluctant to use kraken io

Achingly slow
By , for WP 4.2

The plugin works, but it is achingly slow. Waiting for the results can take up to one minute. Makes it practically unusable.

UPDATE April 26th, 2015: the plugins works like a charm now that it runs on the WPMU infrastructure and does not rely on the (apparently VERY slow) Yahoo servers anymore. Compressing single images takes just a second now for me, whereas I used to wait for a whole MINUTE before.

Right now, the plugin does strip IPTC metadata that I need on my site, which is why I'm not actively using it. Once that problem is resolved, I will reactivate it and adjust my rating and review.

Great Work
By , for WP 3.9.2

Optimises new and existing images. Never had problems.

FYI the images have to be under 1MB to be optimised.

Good Pluging
By , for WP 3.9

The plugin and all of its features worked just fine on my site.
it's well-executed and lacked any of the kludginess you often see with WP plugins.
