What is Image Optimization? (Optimized vs Unoptimized Images)

Image optimization is the process of saving and delivering images in the smallest files without reducing the quality of the image overall.

While it may sound like a complex process but it's actually fairly simple today. You can use any of the many image optimization tools and plugins to automate the compression of images by up to 80% without any noticeable reduction in image quality.

Here's an example of an optimized and unoptimized image

You can observe, if optimized properly the same image could be 75 percent smaller than its original size without any quality loss.

How does Image Optimization work?

In simple terms images optimization uses compression technology like "Lossy" and "Lossless" that help reduce the overall size of the file, without noticeable loss of quality.

What is it to optimize Images?

If you've ever received an order to optimize your photos through your WordPress hosting team or the speed test tool that's all it means is that you need to reduce the file size of your images by optimizing them for web.

Why is Image Optimization Important? What are the Benefits of Image Optimization?

There are many advantages of optimizing your photos, below are the top ones to be aware of:

  • Speedier website loading
  • Improvements in SEO rankings
  • A higher overall conversion rate for sales and leads
  • Storage and bandwidth are reduced (which can reduce hosting and CDN cost)
  • Faster website backups (also reduces cost of backup storage)

Beyond video, pictures are the next largest item on a web page. According to HTTP archive pictures account for around 21% of the weight of a page's total.

Since we know fast websites are more popular in search engines (SEO) and experience better conversion rates in terms of image optimization is something that every business website must perform should they wish to make a mark online.

According to the findings of a Strangeloop study, even a one-second delay in loading a website will cost you 7% in sales. It also results in 11% less pageviews, as well as a 16% drop in satisfaction among customers.

If that's not enough reasons to speed up the loading time of your site You should be aware that search engines such as Google provide preferential SEO treatment to faster-loading websites.

How to Save and Optimize Images for Web Performance?

The key to successful photo optimization to improve web speed is finding the right ratio between the smallest size of the file and acceptable quality of the image.

The three factors which play an integral importance in Image optimization are:

  • Image file format (JPEG vs PNG vs GIF vs tiff )
  • Compression (Higher compression = smaller file size)
  • Image Dimensions (height and width)

If you choose the best combination of all three, you can shrink your image's dimensions by up to 80 percent.

Let's examine each of them in greater detail.

  1. Image File Format

For the majority of website owners, the three primary image formats that really count comprise JPEG, PNG, and GIF. Choosing the right file type is crucial to image optimization.

To simplify things It is best to use JPEGs for images or photos with lots of colors. PNGs for basic images or when you require transparent images. You can also use GIF for images that are animated only.

For those that don't know the difference between each type, the image format PNG is not compressed which means it's a much higher-quality image. However, the downside is that file sizes are much bigger.

However, JPEG is a compressed file format that slightly decreases the quality of images to create a significantly smaller size file.

However, GIF uses only 256 colors in addition to lossless compression. This makes it the ideal choice when it comes to animated photos.

On WPBeginner, we use three different image formats based on the type of image.

2. Compression

Another thing to consider is compression that plays an essential role within image optimization.

There are a variety of types and levels of image compression available. Settings for every depend on the image compression tool you use.

A majority of image editing tools, such as Adobe Photoshop, On1 Photo, GIMP, Affinity Photo and many more have built-in compression tools for images.

You can also save images as normal and then use a web application like TinyPNG and JPEG Mini for easier image compression.

Although it's manual but these two techniques allow the compression of images prior to uploading the images to WordPress as well, which is what we do on WPBeginner.

There are also a variety of popular WordPress plugins, such as Optimole, EWWW Image Optimizer and others that automatically compress images after they are uploaded for the first time. A lot of beginners and even large corporations are using these image optimization plugins due to the fact that it is simple and easy.

We'll explain more about these WordPress plugins in the coming article.

3. Image Dimensions

Normally, when you import a picture from your phone or a digital camera, the image has an extremely high resolution and large file dimensions (height as well as width).

Most often, these images have typically a resolution of around 300 DPI and dimensions starting from 2000 pixels up to. These high-quality photographs are great for print or desktop publishing. They're not suitable for use on websites.

Reducing file dimensions to something more reasonable can significantly decrease the size of an image. You can easily resize images by using the image editing software installed on your personal computer.

As an example, we have optimized the photo using 1.8 Megabytes in size as the original file size and 300 DPI resolution, and dimensions of 4900x3200 pixels.

We decided to use the jpeg format for better compression. We also altered the dimensions to 1200x795 inches, and it reduced the file size to 103KB. That's 94% less than the original size.

Now that you've learned the three most important aspects of image optimization, let's take a review the different image optimization tools available to website owners.
