Why Optimize Images

Google tells you that you need to opmize images. Why?

According to a study by Microsoft, the average human attention span has dropped from 12 seconds to 7 seconds. More shocking though, is the fact that research from Jampp found that the average attention span decreases by a massive 88 percent each year.

What does this mean for you as blogger or if you run an ecommerce store?

In a nutshell, it means if your website loads slowly people will lose simply move onto to another site.

A slow website then means you potentially lose potential customers before it even loads.

According to case study research involving Amazon, Google, and other larger sites, a 1 second delay in page load time can led to 7% loss in conversions, 11% fewer page views, and huge drop in customer satisfaction, 16%.

How To Check Your Speed and Images

Many people just arting out don’t realise how important website speed is.

Often they think there website is ok and don’t test it. Because browsers hold a cached copy, they don’t experience it like a new person visting the site for the first time.

However, a normal user who is visiting your website for the first time may not have the same experience.

In fact,because where the site is hosted matters, people in different Countries will have totally different load times.

So test your website using tools like Pingdom.

Different Types of Images

optimize images jpg and png

There are two main file types you’ll want to optimize for the web: png and jpg.


JPGs (also known as JPEGs) are the most popular file type for images on the web, because they are generally smaller than png files. JPGs are ideal for photographs, or images with color, shadows, gradients, or patterns. JPGs have a huge color pallet and make these type of images look great.

Broadly most people save jpgs in either high, mid or low quality. High quality delivers the full impact of the image but has a much bigger file size. Low quality images start to become pixelated and look more grainy. So imost cases you want to choose a mid to low point for use on the web.

Obviously the size of the image in pixels matters. We will discuss this in a moment.


The main difference between PNGs and JPEG’s is that PNG files can be transaprent.

PNGs are the another commmon file format used on websites.

PNG-24 provides a much higher quality image, however the size of an image file becomes large.

This is where good lossless optimization tools come in.

What To Use and When
Use PNGs for logos, icons and featured images because they are high quality, and offer transparency.

Use jpgs for most other images on your site.


Optimizing Images The Right Way

How To Get The Optimum Image Compression.

47% of users coming to your website expect your webpage to load in under 2 seconds Furthermore, 40% will leave a site if a page that takes more than 3s to load. For this reason, it’s vital that your images are small and so load quickly.

There are two things you can do to properly optimize your images:

Use The Right Dimensions

First of all, save the right size image to you website. If you have a blog then the theme usual will have default dimensions for your blog featured images. As an example that might be 800px by 400px. So, you just need to resize images to fit that size and not use bigger images.

If it is for a blog banner then look up the width of your page. There is a simple chrome extension you can use to measure sizes called Page Ruler. For instance, you can use Page Ruler to measure sidebar widgets to get the right size images in your sidebars.

Save The Right Quality

Lossless compression is the ideal. So what you need to consider os the best way to do this. My top recommendation is to save a jpg file to around 30% of original. For png files you need to use a compression software. So one of the online tools or a tool on your Mac or PC.

There are two ways of optimizing your images prior to uploading:

  1. Using online tools that allow you to upload either single images or a set of images (bulk processing).
  2. Using tools for your PC or Mac that optimize them either as single images or bulk.
