ShortPixel Review: Pros & Cons Of Using It (June 2024)

ShortPixel Review

No one likes slow-loading websites. When it comes to WordPress speed optimization, high-quality unoptimized Images are one of the biggest drains on page load time. Studies show that Website speed is crucial for SEO and overall site revenue. 

Even just a one-second delay in website loading time will Reduce page views by 11%, Decrease customer satisfaction by 16%, and Reduce conversions by 7%. An unoptimized image will still drag down your page loading time even if you use premium CDN and cache plugins like WP Rocket or FlyingPress. That’s why we need to use an Image Optimization plugin. 

There are quite a few image optimization plugins available on the WordPress repository. In this article, we share ShortPixel Review from our own experiences to find out if the ShortPixel Image Optimizer plugin is the right choice for you or not.

We’ll take a deep look into the inner workings of the ShortPixel Image Optimizer plugin, examine the features it offers, real-world performance test, look into the pricing, and finish up by giving you our opinion on whether or not it’s worth the investment.

ShortPixel Review 2024

ShortPixel Image Optimizer is an image optimization plugin with over 7,258,234+ downloads, 300,000+ active installs, and over 550+ 5-star ratings on the WordPress repository. 

I’m very picky about my WordPress theme and plugin choice for my website. Back in 2020, I decided to give ShortPixel Image Optimizer a try, and let me say; it’s by far the best Image Optimization plugin I’ve found in the last couple of years.


ShortPixel has different types of image compression, original image file backup, EXIF data erase, image resizer, etc. With ShortPixel, you can convert any image format to .webp or .avif format ( .webp format is the next-gen image format developed by Google that is much smaller and faster than PNGs or JPGs image formats).

ShortPixel is free to use, and with their free version, you get to optimize 100 images/month; with the premium version, you can optimize an unlimited number of images. 

That’s why in this article, I will cover it in the premium version of ShortPixel Image Optimizer because it’s worth every penny. I’ll go into that more below, but let’s first look at the ShortPixel features, pricing, and my website performance. So, you can decide if it is worth using it or not.

ShortPixel Features

Uploading full-resolution unoptimized images onto your WordPress website hurts your website performance. Significantly, if you use shared web hosting plans, unoptimized images will instantly slow down your website’s total load time and increase TTFB (first time to byte).

After using ShortPixel, you would be surprised to see your site’s compressed images without quality degradation and overall website performance.

Here’s a list of ShortPixel features you need to know:

  • NextGen Image Format Support.
  • Automatic Backup of your original images.
  • Batch image optimization.
  • ShortPixel removes the EXIF tag from images automatically.
  • Cloudflare Integration for better performance.
  • Automatic Image Resizer for larger size images.
  • Different Image compression levels: Loosy, Glossy, and lossless.
  • Automatic Wp retina image optimization.
  • 24/7 customer support.
  • Unlimited website usage with a single API key.
  • Compatible with WPML, watermarking, and NextGEN Gallery plugins.
  • No file size limit.
  • Works with WooCommerce sites.
  • Automatically convert .png to .jpg
  • Convert any image format to .webp or .avif format.
  • Automatic PDF compression, & many more.

Now, let’s take a look at the ShortPixel image compression types.

ShortPixel Image Compression & Optimization

Compression is the easiest way to make your image files smaller by removing data. Image compression is a way to decrease your website’s total size and HTTP requests, and it makes your website faster than ever.

ShortPixel offers three main types of image compression: lossy, glossy, and lossless. 

  1. Lossy Compression (Recommend): Lossy compression permanently removes some data from the original image file, resulting in a significantly reduced overall image file size. Lossy compression also degrades your image quality. However, you can’t distinguish between the original and the lossy compressed photo.
  2. Glossy Compression: Glossy Compression allows you to maintain a balance between decreasing file sizes and optimal quality of images. Glossy compression reduces image file size not as much as lossy compression and can’t preserve Image quality as high as lossless compression. This image compression option is only available on ShortPixel.
  3. Lossless Compression: Unlike Lossy compression, Lossless compression won’t reduce image quality. This compression only removes additional, non-essential EXIF data and does not compromise image quality.

Which Image Compression is Best For You?

Well, It depends on your website needs. 

With lossy compression, you end up with the highest image compression possible, but it will decrease the quality of your images (most of the time, you won’t notice it). I recommend using Lossy compression if you run an e-commerce site, blog, or portfolio site.  

And with lossless compression, you get high-quality images with low image compression. As a result, you end up with a high image file size. If you run Photography showcase sites, I suggest you go with lossless or Glossy compression.

If you’re curious, I use lossy compression on all of my sites because this is an easy win for performance and overall on-page SEO. Note: The lossy compression process is irreversible, meaning all image file information will be removed permanently (Don’t worry, ShortPixel keeps a backup of all your original image files).

ShortPixel Pricing in 2024

ShortPixel has both free & premium plans. With the ShortPixel free plan, you get 100 free credits/per month. (PS: Credit implies a number of images). With the ShortPixel premium plan, you can optimize from 100 images to an unlimited number of images per month. They offer two types of premium plans: unlimited subscription and one-time subscription.

ShortPixel Unlimited Plan
ShortPixel unlimited pricing

ShortPixel unlimited plan starts at $9.99/month or $99.90/year. As the name suggests, with this plan you can optimize an unlimited number of images. Along with usage ShortPixel also offers 500GB CDN traffic/month for faster image loading time.

ShortPixel One-time Plan
ShortPixel One-time Plan

If you need to optimize a large number of images but do not feel the need to invest in a monthly or yearly subscription, ShortPixel offers one-time payment plans. ShortPixel one-time plans start at $19.99 to $99.

ShortPixel’s $19.99 plan lets you optimize 30k images. However, after some negotiation with the ShortPixel team, our website visitor will get an extra 50% image credits bonus.

Note: ShortPixel’s one-time plan doesn’t offer CDN services. However, your credits you’ll never expire with a one-time plan. ShortPixel’s one-time plan is more than enough for small business owners and bloggers (I’m also using this plan). You can easily add more images to your account if you exhaust all your images. 

DEAL ALERT: With our unique ShortPixel coupon code, you get an extra 50% credit with all premium plans. If you want a ShortPixel yearly subscription, you’ll also get two months free.

ShortPixel Performance

I always test performance when installing a new theme or a speed optimization plugin. I prefer to use Kinsta or CloudWays hosting with the GeneratePress theme & WP Rocket cache plugin to test my website performance. Here’s the result of my website performance before and after using ShortPixel:

ShortPixel Performance

As you can see, After installing and optimizing all of my website images, ShortPixel can reduce website loading time and reduce overall page size and HTTP requests.

ShortPixel premium allows you to transfer any image format .webp format. So, when you test your website performance on Google PageSpeed Insights, you will not see the “Serve images in next-gen formats” error. It’ll help you to pass new Core Web Vitals results.

ShortPixel General Settings

ShortPixel general settings are pretty straightforward. As you can see here you’ve to select your image compression type, backup, Image EXIF, etc.

  • SmartCrop: No. ShortPixel uses AI to generate thumbnails. It’s completely up to you whether you want to use AI-generated thumbnails on your blog posts.
  • Backup: Yes, enable this option. In the future, if you want to restore the optimized files to the originals or re-optimize the images using a different compression type this option is a lifesaver.
  • Remove EXIF: Yes, enable this option. ShortPixel automatically removes image meta tag information.

  • Optimize Retina images: Yes. If you don’t know what retina images are, it allows the screen to show more detail and improves the viewing experience.
  • Optimize other thumbnails: No. it’s up to you, enable it if you have too many image thumbnails.
  • Convert PNG images to JPEG: No. I don’t use this option because I already convert all types of image formats to WebP format.
