6 Best WordPress Image Compression Plugins Compared & The Winner Is…

I remember a time when compressing images on this blog used to be free.

Thanks to the developer of the Smush.it plugin, we got very spoiled and became used to free image compression.

In the last few months, everything we knew about free image compression has changed. Now, most of the WordPress plugins which are available online offer a small quota of free compressions & then you have to pay.

So in this post, I thought it would be a good idea to look at all the existing image compression tools out there (free & paid).

Those who have a small or medium sized WordPress blog can use multiple WordPress plugins to optimize all of their existing/future uploads for free. It might be time-consuming, but I know that when you are starting out, money is more important than time.

For those who have a medium sized or a large blog, you may want to consider going for a paid option. This will help you load your blog faster & will keep your readers happy.

Here’s the formula:

  • Happy readers = Good blog = Better ranking = More money

That’s a good formula, but let’s get down to the real business. Here are some of the best image compression WordPress plugins.

(Like always, I will try to put as many important points as possible about these plugins to help you make an informed decision. Cool?)

Best Image Compression WordPress Plugins: Make Website Faster

Here we go…

1. ShortPixel

Shortpixel WordPress Image Optimization service

ShortPixel is a developer specifically for WordPress. They offer both free & paid accounts (like all the others). Though, there is one really cool part about this service which I’ll tell you about in a minute.

  • Supports JPG, PNG, GIF & PDF.
  • Restore original image anytime.
  • Compress all old uploads with a single click.

It’s easy to setup & the interface is very pleasant. You will see what I mean when you start doing bulk image compression with this plugin.

Tips on using:

Add the API Key from Settings > ShortPixel.

Head over to Media > Library > Bulk ShortPixel to optimize your old images.

Bulk Image Optimization Shortpixels

One cool thing about this plugin is you can deselect thumbnails from compression.

This ensures that your free quota is only used for the bigger sized images, which in most cases is the culprit for your slow loading pages.

Saved bandwidth using Image compression

This plugin is updated on a regular basis & has 20K+ active installs with a 4.7-star rating.

ShortPixel is an ideal solution for image & PDF compression in WordPress.

2. Imagify Image Optimizer

Imagify Image Compression

This plugin is from the developer of the WP-Rocket plugin.

It has all the essential features such as bulk compression and image resizing.

It offers 3 different levels of compression & depending upon your blog type, you should pick 1 of the 3:

  1. Normal, a lossless compression algorithm. The image quality won’t be altered at all.
  2. Aggressive, a lossy compression algorithm. Stronger compression with a tiny loss of quality which, most of the time, is not noticeable at all.
  3. Ultra, the strongest compression method using a lossy algorithm.
    • With the backup option, you can change your mind whenever you want by restoring your images to their original version or optimize them at another compression level.

In the coming days, they also plan on adding a feature to convert images into WebP format.

This plugin is also compatible with WooCommerce and NextGen Gallery.


  • Supports JPG, PNG & GIF.
  • Resize images on the fly.
  • Resize based on percentage.
  • Support for PrestaShop, Magento, Shopify, and Joomla coming soon.
  • Images above 5Mb will only be compressed with the paid account.

Free account:

  • 25 MB free every month.
  • Bonus 25MB at sign-up.

Paid account (10,000 images):

  • $4.99/month for 1 GB of data.

Imagify pricing


Ease of use:

Onboarding is pretty easy & like other plugins, you need to create a free account & get your API Key.

The plugin is easy to use & once you have configured the settings, you can start using it right away.

You can enable or disable the option to compress thumbnails.

Apart from compression, one thing that I enjoy the most about this plugin is the interface.

It’s sleek & feels like you are in a game.

Bulk Image Compression WordPress

Overall, this is a good plugin & since it’s from the same people as the WP-Rocket plugin, I believe it’s a good choice for anyone looking for reliability.

The only thing that you might want to consider before opting for this one is the price.

3. Optimus

Optimus WordPress image compression

This is another popular solution which I’m sure many of you will like. Optimus seems to be a great alternative for the Smush.it plugin as this will let you compress all images <100Kb for free.


  • Support JPEG, PNG.
  • Bulk compression.

Free account:

  • Unlimited compression of images < 100Kb.
  • Supports Progressive JPEG.

Paid account:

  • $19 one time fees for unlimited image compression.
  • Maximum file size 5MB.
  • Supports WebP conversion.

Optimus Settings

For the price, Optimus HQ is worth every penny.

But I would really like to see improvements in their bulk compression feature. If you stop the bulk compression in between & start the process later, it will start compressing all images again. It would be better if it could skip those images which have already been processed.

4. TinyPNG: Compress JPEG & PNG images

TinyPNG is a somewhat popular online service to compress images.


  • Automatic compression for new images.
  • Supports JPEG & PNG files only.
  • Bulk optimization.
  • Resize image feature.
  • Convert CMYK to RGB.
  • Single API can be used for multiple sites.
  • No file size limits.

Free account:

  • 500 images compressed each month.

Paid account (10,000 images):

  • 10,000 images costs $85.50 (One of the most expensive for heavy users).

TinyPNG WordPress API Compression

Using the plugin:

After activating the plugin go to Settings > Media.

Get your free API key from here, add it & configure any additional settings you want.

TinyPNG WordPress Plugin

Go to Media > Compress all images & start compressing all of your old images. You can also go to the media uploader & selectively compress individual images (which is a good idea to conserve your quota).

5. ImageRecycle

Optimize WordPress Images & PDF files

I talked about this one in an earlier post on online image compression tools.

While researching for this post, I got to know more about their WordPress plugin & I signed up for a free account.

One cool thing about this plugin is it lists down all the images in your theme folder. You can select individual ones or you can select all & compress those images. Preeeetty cool, huh?


  • Supports JPG, PNG, GIF & PDF files.
  • All plans support multiple websites.
  • Supports sub-accounts & you can define a quota for it (good for agencies).
  • Supports restoration of original files (images + PDF) for one month.
  • Compress all previous images in WordPress with one click or compress images selectively.

Free account:

  • 15-day trial.
  • 100 MB quota.

Paid account (10,000 images):

  • $30 for 10K images.
  • Valid for 1 year.

Imagerecycle Paid account

Ease of use:

The plugin is pretty easy to use & in most cases, it auto-detects your API if you are logged into their online portal from the same browser.

  • Note: It directly leads to the media uploader for compression which might not be good for users. The first screen after activating the API should be the plugin settings.

Anyway, you can access it by going to Settings > ImageRecycle.

When I was testing this plugin, I realized my blog slowed down a lot. This could have been for multiple reasons, so it should not stop you from trying it. But since it happened with me, I believe it’s good to at least let you know.

Imagerecycle WordPress plugin

Once you have setup the settings, go to Media > ImageRecycle to start compressing.

One thing which I really like about this plugin is you can sort images based on size, which is useful when you want to take care of really large images first.

Overall, their WordPress plugin is pretty solid & could be your next image optimization WordPress plugin.

6. Kraken

Kraken Image Optimizer

This is another paid plugin that is quite popular.

With 10K+ downloads & an overall rating of 4.7/5, it looks very promising.

Their web service lets you download & compress images from a web page by downloading all the images into a single zipped folder.


  • Supports JPG, PNG & GIF.
  • WP-CLI supported.
  • Keeps backup of original image in cloud storage.
  • Image resizing.
  • Preserve selective image EXIF data.

Free account:

  • 100 MB one-time testing only.
  • Maximum allowed size – 1MB.

Paid account (10,000 images):

  • $4.50/month (calculated relative to other services).

Kraken pricing

Ease of use:

The plugin is also straight-forward to configure like all the other image compression plugins on this list.

Here is what the settings page looks like:

Kraken io Image Compression WordPress

The option to preserve specific data like Copyright is pretty smart.

It would be good if other plugins also follow this trend.

One big thing missing from this plugin is bulk image optimization. So it’s not ideal for those who are looking to optimize existing images. You will need to manually compress them.

Here is how to configure this plugin:

(Since page speed is one of the factors for a better user-experience, and also a search engine ranking factor, we can expect similar plugins launching in the coming days. I will keep adding new WordPress image compression plugins as I discover them.)


I have compiled those services from above list that offer a free image compression quota every month. If you have a small or a starter blog, this should be enough to take care of your monthly need.

Services that offers free image compression quota every month:

Paid services based on features & pricing:

These are the paid services that I like based on features, user experience & pricing.

  1. Optimus
  2. Imagify
  3. Kraken
  4. ShortPixel
  5. ImageRecycle
  6. TinyPNG

In my opinion, TinyPNG hardly deserves to be on this list due to its high pricing & limited features.

Imagify is what I would recommend for a paid image compression service.

Again, I will keep adding new WordPress image compression plugins in the future.
