Images are the most important factor behind website load time as they are good for explaining things quickly and can also be used as a content enhancer.

However, having lots of images in your content can slow down the loading speed of your web page considerably. A slow loading website will make you lose your customers.

So, it becomes very critical to optimize images on your website to make sure that your website loads fast for your visitors, and you can achieve higher search engine rankings.

Today I am going to tell some of the fantastic WordPress plugins that you can use to optimize images on your website and to enhance the overall loading speed of your website.

1. ShortPixel -

ShortPixel plugin is simple to use which comes with a clean interface and useful features. You need to subscribe to ShortPixel to get the API Key and get the plugin going.

Upon subscription, you receive 100 free credits/month. While it isn't as many as those offered by TinyPNG they should be enough for the average WP blogger. Also, this plugin only counts the images they succeeded optimizing by at least 5%. Otherwise, no credits are charged.

What I felt is missing in the plugin - an option to keep EXIF data in images. Some (photographers mainly) could find this feature very useful.


The plugin also offers a backup and restore solution for the optimized images.

shortpixel-2Plans start at 4.99$/month, and one-time packages are also available. You can optimize 10,000 images with $9.99 which is a good bargain especially if you have large images. We recommend you to give it a try.

2. Compress JPEG & PNG -

What I like about TinyPNG is that they have the option to optimize only certain image sizes, they offer the option to resize the original image (it can lead to great savings), and they have a generous free monthly plan (500 images/month for free).

They didn't offer any backup option, the optimization results are in KB/MB (it is rather confusing), and there is only the option to optimize the images as lossy.


While testing their plugin I could notice blurry sections on some pictures. While they didn't look awful, it wasn't nice for the trained eye either.

TinyPNG has a generous monthly plan of 500 images and also the option to pay exactly what you need. So if you require optimizing only 3500 images, then you only pay for that.The cost for optimizing 10,000 images is $85 which is rather high.
