Good but slow.
By , for WP 4.6

This plugin is very good. It optimized my png files that I thought already make it small lol. I really love that it make wepb image for even smaller. The down side is it is very slow especially if your site generate many image size. You can't choose which image size to optimized. I spent 12 hours for 1500+ images that quite long. I love the pricing. You an buy it at $19 sometime and use it for unlimited images. No more charge. Many plugin charge per image or size but this plugin is unlimited! Thank you so much.

Everything fine

Above all: Optimize your images BEFORE you upload them. This plugin did nothing for me, other than taking some alibi bytes off. Sorry but nope.

Hey there, nice Work !

automatically small images

It work well, but does not collect all the images from the archive folders.
Plugin selects only images uploaded WP library, but small images that were created automatically by template, does not optimized.

Can't get better than WebP + Lossless compression
By , for WP 4.5.1

I have become a huge fan of WebP as of late. It is a very underutilized feature that more website owners should be using. I have decreased all of my image sizes by over 20% with WebP, and that is on top of what I was already getting with the lossless compression. Love knowing my images are as small as possible to ensure fast load times.

nice and reliable plugin

Easy to install and use. Ideal as a scalable tool.

Good plugin but..

there is no option for lossy compression, so the filesizes really hardly become smaller.

Other plugins offer a choice between lossy and lossless. EWWW for example even offers lossless, as well as 2 different ways of lossy compressing images (jpegmini and tinyjpg) and the results are very good (jpegmini resulting in bigger files but high quality, tinyjpg resulting in smaller sizes and slightly lower quality) with filesizes much smaller than Optimus.

My point is: you should also add a lossy option, then the plugin will be much more complete and will deserve 5 stars.

UPDATE: since you added Webp - now 5 stars!

Stop looking around and just download this already!

There are very few plugins that just simple work, without any issues at all. This is one of them. I knew I needed to do something to optimize the images on my site, but I kept putting the task off because I thought it would be too time-intensive. Little did I know, Optimius would take care of everything in a few simple clicks. I installed the plugin, and let Optimus scan and compress my images, without losing ANY of the image quality. It worked like a charm! I highly recommend you invest in this simple plugin. Your site visitors (and search engines) will appreciate it.

If you want to sqeeze your images...

...look out for Optimus. I´ve installed the premium-version "Optimus HQ" (good deal for 29 EUR / year), with the free version you´re a little bit limited. If you don´t want to pay anything, that´s not the plugin of your choice.

It also generates webp-images and let (since today...) also re-generate webp-images for already optimized pictures. And squeezes all the rubbish out of your images.
