Optimize images in WordPress like a pro

Here is a first blog post in a series, it’s about how to optimize images. I’m a member of several forums on Facebook and it seems like a lot of people have problems knowing how to optimize a WordPress site. So here are a few things that will speed up your WordPress site. If you follow my pieces of advice and your site’s performance¬†doesn’t improve by at least 40-50%, then I promise to eat my hat (just kidding, I don’t even own a hat)! But three relative simple advices can make a HUGE performance improvement. ūüôā

This is part one of the blog post series about how to optimize WordPress. Part two and three will be released in a few days and will cover CDN¬†(follow this link and you’ll see the CDN provider I use and will write about, as a bonus you’ll get $10 in credit for free just by signing up). Finally, part three will be about cache. I will let you know which plugin that is the fastest of all I’ve tried. And the best of all, it’s free!

Why optimize WordPress?

Well, because if you don’t you will probably have a pretty slow site. And to attract visitors and to be able to rank high on Google (and other search engines) your site needs to be fast. A lot of people use slow themes, install way too many plugins, use a bad host and so on. But even if you do that there are things you can do to improve the performance of your site. In this blog post, I will give you three pointers that’s easy to implement, even if you’re not too technical. If you find something unclear or hard, write a comment and I’ll try to help you.

Step 1: Optimize images

If you have a site with images that are several megabytes large, of course, your site will be slow! So it’s crucial to optimize your images. Quite recently I found my new favorite plugin for WordPress to optimize images. It’s called ShortPixel¬†and right now (if you hurry up) you can get a Lifetime account for only $25. Yeah, you read that right. Here’s a link to the deal! But I can’t promise that the deal is live when you read this. It’s still available now, 4th of December.

What is ShortPixel?

Source: ShortPixel

The best thing and I agree with them, is that ShortPixel really optimizes images and make them smaller without making them look ugly/pixelated. It’s like magic for your images. You simply install their plugin, do some settings and never have to think about it again. The best part is that the optimization is taking place on their servers, so even if you use a slow host, all the heavy-lifting is done by them reducing the size of your images. The first time you install the plugin, I recommend that you let¬†ShortPixel¬†do a bulk optimization of all your images. It will take a while but it’s worth it! After that, the optimization will take place as soon as you upload a new image.

ShortPixel makes it easy to optimize images

So, how much will ShortPixel help you?

That totally depends on how many images you have on your site. The more images you have the more important it is. But let’s take a look at my site as an example. I thought I had optimized my images pretty good, but ShortPixel proved me wrong. So, after ShortPixel¬†done it’s magic this is the statistics:

ShortPixel Statistics

As you see, ShortPixel was able to save over 68% of disk space. Think how much faster your site will be if your images are 68% smaller in size (disk size that is).


You might wonder what settings I used. First I tried to use¬†Lossy, but the compression on my beautiful cow image on the start page¬†got a little too compressed for my taste. But when I used¬†Lossy I think the average compression was nearly 80%, which is quite amazing. If it wasn’t for my large cow image I would have used¬†Lossy. Instead, I use the medium compression option,¬†Glossy. There’s also a third option called¬†Loseless.

Some more great features with ShortPixel

ShortPixel¬†supports the new image format WebP format. WebP can save up to 25% when comparing with PNG. If you don’t know what WebP is, read this great blog post¬†written by the creators of ShortPixel.

Another thing you can choose to activate in the settings is to let ShortPixel convert PNG to JPEG if it’s possible to maintain the quality and make the image smaller. You find this setting under the advanced tab.

The last feature I’m going to mention is that ShortPixel is even capable of optimizing PDF files.

For a full list of all the features, I suggest you visit their website. ShortPixel also has a very good blog that you should follow.
