How does ShortPixel Works?

The procedure of ShortPixel differs according to how you’re going to use ShortPixel for compression.

Basically, there is two way to use ShortPixel for compressing images, PDFs, and animated GIFs.

  • 1
    WordPress Plugin
  • 2
    Online Compressor

I will briefly talk about how to use each method to optimize your images without compromising on quality.

How to Use ShortPixel WordPress Plugin

If you have a WordPress blog, using ShortPixel is pretty much easier. Once you installed ShortPixel WordPress plugin on your WordPress blog, it will automatically optimize images such as JPG, JPEG, PNG and animated GIF files and eBooks, guides and tutorial PDF files automatically no matter how you upload them to your WordPress site.

Here’s how to work with ShortPixel WordPress plugin.

  • 1
    Login to your WordPress admin by using your admin username and password.
  • 2
    Navigate to Plugins >> Add New >> Search “ShortPixel”

  • 3
    Install ShortPixel plugin and Activate it.
  • 4
    Create your free ShortPixel account by clicking the button below and grab your API key.
  • 5
    Copy and paste your ShortPixel API key to Settings in ShortPixel. Save your Changes.
enter shorpixel api key wordpress

Enter Your ShortPixel API Key

Now you have successfully integrated ShortPixel with your WordPress blog.

Your API key is the fundamental requirement to running ShortPixel successfully on your blog. Once you’ve optimized a couple of images and PDF files on your blog, you can see the details of them in your ShortPixel account’s Analytics pages.

So, it all makes sense to protect your ShortPixel API key to save ShortPixel credits and collect accurate results for optimized content.

As you’ve integrated ShortPixel with your WordPress blog, now you can optimize images in WordPress blog in three different ways.

  • 1
    Optimize Images Automatically

When you upload a new image to a post in WordPress editor, ShortPixel will optimize them automatically. You should be known that When you upload an image to WordPress, it creates 6 different variations for situations like image thumbnails. You can learn about WordPress image sizes and qualities over here.

Therefore, you should be aware that if you uploaded 10 images per post, then it will automatically create 60 image variations, so it will cost 60 ShortPixel credits, if and only if the compression ratio is or higher 5%. Yes, If your images aren’t optimized above five percent ratio, it won't cost ShortPixel credits.

    Optimize Images in Bulk

What if your blog has already hundreds of images installed? How would you optimize them without removing existing images?

Luckily for you, ShortPixel could do this time-saving activity for you easily. In fact, ShortPixel could optimize existing images in your media library and replace older or unoptimized ones automatically or have older ones as a copy and replace them with new, optimized images. I would say this is a totally helpful feature as I know some of you have 1000’s of unoptimized images in your blogs.

    Optimize Images upload via FTP

If you’re a web developer and using FTP to upload files to your WordPress blog, there’s nothing to worry about optimizing images because ShortPixel does it for you no matter how you upload images to WordPress.

You could work on your blog in another tab while ShortPixel optimizing images for you because of it no way causes any harm to your blog process.

How to use ShortPixel Online Compression Tool?

Not all people use WordPress. Some of you may be using other blogging platforms such as Google’s Blogger and Yahoo’s Tumblr. As a blogger, you should be really careful about your web pages sizes. Because it matters a lot than the content itself! 🙂

If you are building a custom website (ex: for lead capturing, sales pages, agency landing page) or an e-commerce store using Woocommerce or Shopify, or a generic blog using Squarespace and Magento, then you should be wanting a way to optimize images online.

ShortPixel Free Image Compression tool makes optimizing images not only easier but also faster and efficient.

Here are a few reasons why ShortPixel online image compressor is best on the Internet (I was gonna say in the market, Phew!).

  • Bulk Image Optimizer

You can upload up to 50 images (JPEG, PNG) and animated GIFs at once. If you look at other competitive image compressor tools, you will notice that most of them limit it to below 50 amount, mostly 10 or 20. And you could download multiple files at once. ShortPixel will zip your images into one folder and let you download it faster.

  • No Upload file size

If you need only one reason why you should use ShortPixel above any other online image optimization tool, be it how much size of each object it allows uploading. If you’re a photographer or a photoblogger, your images may be 10MB, 20MB or even 30+ MB in file size.

ShortPixel doesn’t care about upload file size. It’s all doing is reducing image sizes while optimizing images for its best performance.

  • Optimize animated GIF files

To be honest, I have been using about a dozen of online image compression tools prior to ShortPixel. Not any of those have the ability to optimize animated GIFs. if you know animated images or GIFs normally have much larger file size compared to non-animated ones. Therefore, ShortPixel Online Image Compressor is an excellent tool for optimizing all types of images.

  • Choose Compression level

ShortPixel allows you to select the compression level while uploading images. Basically, there are three levels - Lossy, Glossy, and Lossless.

However, you couldn’t select a pre-file size or an output file dimension with ShortPixel. These compression levels give you the control to optimize images accordingly. Check below compression level graph to understand the uses of each part.

ShortPixel PDF Compressor Tool

PDF or Portable Document Files is a global standard file format which runs on all operating systems including mobile OS. That’s why you see reports, white papers, eBooks and online guides are in .pdf format. 

If you’re offering PDF files as “Content Upgrades” on your blog to collect more leads, then optimizing them would not only save monthly bandwidth but also improve user experience too. It doesn't affect highly, but it still does.

So, you could optimize PDF files online to reduce file size reasonably. ShortPixel Online PDF compressor allows you to upload up to 50 files at once. Therefore, it won’t take much time for you to optimize multiple PDF documents online with PDF Compressor.

ShortPixel Features

JPEG, PNG, WebP and GIF Image Compression

ShortPixel supports all major image types no matter how much or how you upload them. Here’s how I use them for my blog and other marketing campaigns.

  • JPEG

Also known as JPG. It’s the shortened name for Joint Picture Experts Group. I use this format basically for colorful images without white color background. When compressed it won’t save image quality. Best for post thumbnails featured image etc.

  • PNG

PNG stands for Portable Network Graphics. I regularly this image file format because it saves image quality at very best when compressed. Best use is for screenshots, images with white background.

  • WEBP

A new image format that provides superior lossless and lossy compression for images on the web. WebP image format is initially released on ‎30 September 2010 and developed by Google. According to Google Developers, WebP lossless images are 26% smaller in size compared to PNGs. Use ShortPixel image compressor to optimize WebP images furthermore.

  • GIF

Graphics Interchange Format or GIF image type have different standards, particularly 87a and 89a, developed in 1987 and 1989 respectively. The higher the bit format (basic GIF format starts from 8 bit, which is similar to 256 variations (2^8)), it supports more colors.

ShortPixel supports for most GIF standards, so you could clearly reduce GIF size, so which means reduced bandwidth and increased page loading speed for your websites.

Developer API

If you’ve built a custom tool or software for clients, you could integrate ShortPixel to your software.

ShortPixel is a SaaS (Software-as-a-service) app. Therefore, it runs on cloud and you could expect high uptime guarantee (ShortPixel runs on Amazon AWS). As the wide-variety of services, it offers different ways to serve people to optimize visual content.

With developer API, you could run custom applications, connect multiple tools and importantly build tools that could optimize offline images for your own purposes!

  • Reducer API - Shrink an image based on the URL of the image. The image should be available online to be shrunk via API.
  • Post-Reducer API - Shrink an image which is not available online. You can call it from any programming language via POST HTTP call. Easiest POST request might be might through Java.

Apart from Developer API, you could use ShortPixel technology to build tools that optimize images through…

Unlimited Websites

The best advantage I see of ShortPixel is that the Limitless. You could upload images with any file size and now you could use it on unlimited websites. ShortPixel pricing is also unbelievably cheaper than most.

So, if you have multiple websites (I suppose you have more than one), ShortPixel is the best bet for you now. Because it doesn’t limit websites that you could integrate. 

Compare Original vs Derivative

As marketers, we tend to do tests to find the optimal variation to grow our campaigns. One fascinating feature of ShortPixel that is most helpful is the comparison of original image versus derived image.

It allows you to see how effective each compression level for your project is.

Sub Accounts

If you run an agency or you are offering SEO services for clients, then this is a good news for you.

You can create sub-account under your personal account and limit its resources. For example, if you have two clients who have subscribed to two different plans, you could offer them different sub-accounts such as 10,000 monthly credit for the first customer and 25,000 monthly credit for the second customer.

Optimization report

ShortPixel tracks usage automatically for your account. The details are limited to previous 40 days only and pretty basic. However, it’s the most you want to know as more advanced details doesn’t help your business, but your happiness. I would say it could be enhanced a bit more, but, the developer team has expressed that they are going to be.

Free 100 Credits per month

It’s totally free to create an account in ShortPixel. A free ShortPixel account receives 100 credits in every month for free.

Even you buy a one-time credit package, the free credits will be used before purchased credits. That’s a really good news for bloggers who run the business on a budget.

ShortPixel Referral Program​​​​

ShortPixel has a tempting referral program which allows free account holders to increase their monthly credit size for free.

Once any person signed up to ShortPixel through your referral link and optimized 50 new images that have not been optimized before, you (referrer) and the person will receive 100 free image credits per month for free for lifetime!

The maximum referral credit you could earn is 1,000. It is far enough if you run a small-sized blog.


 

Pro Tip

Share your referral link with friends in social networks, so you could easily get 10 people to sign up through your referral link.

Is ShortPixel for Whom?

Without a strategy, you don’t know what you are doing.

Summing-up

Google has officially announced explicitly a few years ago that they are using web page loading speed to rank web pages in Google SERP.

Amazon has found that every one second delay of loading web pages could cost them around $1.6 billion in sales!

At the end of 2016, the number of mobile internet users surpassed the number of desktop users. According to Google's new industry benchmarks for mobile page speed, mobile visitors don’t wait more than three seconds if your website fails to load on first.

Page speed is a direct cause for conversions, website's total performance, the stability of your business and overall revenue.

As we know, one major culprit for slow loading web pages is large-sized visual content.

You can easily reduce the size of web pages by simply compressing images. There are quite a few online image compressor tools online out there.

However, not all of them are powerful enough to compress your images as you want. Some tools are lack of support for image formats and some have certain limits such as file size allowed to upload.

ShortPixel would be your first and foremost shot if you have used it a few times.

It has a free plan which gives 100 credits per month and you can easily increase the free credit by 1,000 by referring your friends to ShortPixel. If you have a blog or a business which needs much more than 1,000 credits per month, there are fair one-time and monthly plans.

I personally have a ShortPixel account that is subscribed to Short plan. Have you used ShortPixel before? So, what are your thoughts about this compressor tool?
