It’s no question that the speed of your website is one of the most important factors. It attributes to the overall success of your website. The faster it loads, the lower your bounce rate will be. Also, speed is an SEO ranking factor. Also, your visitors will just plain be much happier if your site loads quickly. One way to reduce load times is to compress images. With that said, let’s take a look at the best WordPress image compression plugins available. Looking for a list of the best WordPress plugins for any website? See this post.

Compress JPEG & PNG images

Compress JPEG & PNG images

Basically, it uploads your images to TinyPNG or TinyJPG and figures out the best compression option for your website. Here is a list of all of the features of this plugin:

  • Optimize individual images already in your media library.
  • Easy bulk optimization of your existing media library.
  • Resize large original images by setting a maximum width and/or height.

imagify WordPress image compression plugins


I use Imagify for all of my sites. It’s free for up to a certain amount of data, but after you exceeed that, you’ll need a paid plan. However, it makes image compression a snap, and I have seen some of the best image compression from this service. I have seen size savings up to 80 and 90%. That’s just incredible. You determine the settings, and it’s great for when you already have a site built, and you need a plugin that will run through a massive website on autopilot.

It has 3 modes: Normal, Aggressive and Ultra. Normal is completely lossless in quality. Aggressive compresses your images further, with only slight quality loss, which is usually not noticeable. Ultra sacrifices some quality for maximum compression.

WP Smush image compression

WP Smush

Built by WPMU Dev, this plugin does a good job of compressing images. It works like Imagify, but is part of the WPMU Dev suite of plugins. The main features of WP Smush are:

  • Optimize your images using advanced lossless compression techniques.
  • Set maximum width and height and large images will automatically scale before being added to your media library
  • Process JPEG, GIF and PNG image files.
  • Optimize any image in any directory.
  • Asynchronously auto-smush your attachments for super fast compression on upload.
  • Manually smush your attachments individually in the media library, or in bulk 50 attachments at a time.
  • Smush all standard web-sized images 1MB or smaller.
  • Smush images with no slowdown using WPMU DEV’s fast, reliable Smush API.
  • Global and individual settings for Multisite
  • View advanced compression stats per-attachment and library totals.

And if you upgrade to the PRO version, you can gain more compression and you can even smush images up to a whopping 32MB in size!

One Standout Feature of WP Smush

You can compress any image in any directory. In addition to smushing your media uploads, you may want to compress the images stored in other folders. Smush now lets you compress any image in any directory so that you can optimize all the images on your site – including NextGEN images and the images in EVERY WordPress plugin and theme package!

So which WordPress Image Compression Plugin is the best?

Each plugin has its pros and cons. I looked around for a long time before deciding using Imagify. It makes the whole process quick and easy. All I do is upload the plugin to one of my websites, click a couple of buttons to adjust the settings, and then I let it run wide open. After a while, if I do this on an existing site, all of my images, past and present, are optimized to my liking, with nearly 0% visible loss in quality. It really depends on what you are using it for. If you have a lot of PDFs or animated GIFs, ShortPixel may be the choice for you. If you want even the images in themes and plugins to be optimized, you’d pick WP Smush.
