Resmush.it image optimizerThis WordPress image optimizer provides you with great features to help you improve your site speed while keeping your images crisp and clear.

It utilizes their reSmush API to help you optimize your images and determine what level of optimization you want for your uploads. On the other hand, however, it doesn’t offer varying compression levels, and images are also limited to 5MB in file size.

EWWW image Optimizer

EWWW image optimizer

This image optimizer is pretty great for your WordPress blog. Right after you install it, it’ll automatically optimize any images, as long as they’re in JPG, PNG or GIF.

If you want to optimizes previous images (say, from your Media Library), it also comes with a function to help you do that.

The optimization here happens locally, meaning everything is taking place on your own servers by default. This cuts down on the loading and processing speed. However, if you don’t have the appropriate permissions, you will have some difficulties setting the whole thing up.


Smush image optimizer

This WordPress plugin is one of the bigger names in image optimization.

Here, you’ll get the standard optimization happening as soon as you activate the plugin, with the app running quietly in the background.

This plugin has a lot of features – depending on what you pay for. They have both free and premium options, and obviously the premium features are the best.

For example, you have the option to do bulk image optimization, but if you’re on their free plan, you are limited to 50 files at a time.

The plugin uses lossless optimization, but if you have the pro plan, you have the “Super-Smush” feature that can optimize each image multiple times with lossy compression.

Tiny PNG

What sets Tiny PNG apart from the rest of the plugins on this list is that they use only lossy compression methods, meaning you’ll get a huge reduction in file size while your images are kept at mostly the same quality.

Because of that, there aren’t a lot of configuration options in their Settings. You can still choose the image sizes, max resolutions, and so on, however.

It’s a good option when looking for the best WordPress image optimizer.


Imagify image optimizer

Last, but not least, we have the Imagify WordPress image optimizer.

Even though it’s free, it still presents you with a wide range of options you can configure. You can begin with the optimization intensity – Normal, Aggressive (the recommended setting) and Ultra. Normal may not compress enough, while Ultra can end up blurring and decoloring your images.

All you need to do is get their API key and optimize your images: individually or in bulk.
