Image Optimization for WordPress

I am often asked which image optimization system I recommend with WordPress. There are many available now and it is important to me that they are fully compatible with WP/LR Sync and WP Retina 2x. Here is a list of them. If you have any problem or anything to say about those optimizers, please let a comment.

Avoid using S3 with WordPress. It was not mean to be used with S3, and even if there are plugins are allow you to do that, it is basically a hack. You will encounter too many issues with too many plugins.

1. Serve your content through a CDN

The best CDN for me is currently CDN77. It’s super fast, the system is very neat and easy to install. I am currently using it for my website Haikyo, with a custom cdn subdomain.

Another good option is the famous MaxCDN. If you are looking for a free alternative, with less performance, then have a look at CloudFlare. If on the contrary, you are looking for the best performance possible, you have a technical team and load of cash, then you might be interested in Fastly. None of those solutions require you to alter your WordPress install.

2. Optimize your Images

Here is a list of plugins that optimize images in WordPress.

1. EWWW Image Optimizer

Works with WP Retina 2x and WP/LR Sync.

The developer is super friendly and enthusiastic, he really does his best for his clients and compatibility with other plugins. The plugin works very well. You can pick a plan here: Plans for EWWW Image Optimizer. The only downside is that the UI looks a bit clunky and it might not super easy to use for the average user.

2. ShortPixel

Works with WP Retina 2x and WP/LR Sync.

The developers worked with me on the compatibility very nicely. I used this plugin and it also worked perfectly for me. It’s simpler than EWWW but has fewer options and no free alternative.

3. SmushIt

Should works with WP Retina 2x and WP/LR Sync.

They contacted me to work on the compatibility in the past, so it should still work. The plugin is really simple, works well. I feel like it reset the optimized status of the images from time to time. Much simpler than EWWW, quite similar to ShortPixel actually.

4. Imagify

Waiting for more testing…

I recommend you to use WPEngine or SiteGround. They are both excellent hosting services and work perfectly with all my plugins.
