How does Image Optimization function?

In simple words in simple terms, image optimization is achieved by using compression technologies such as "Lossy" and "Lossless" that helps reduce the total size of files without causing any loss in quality.

What is it to Optimize Images?

How to Save and Optimize Images for Web Performance?

The key to successful image optimization of web pages is to find the perfect ratio between the smallest size of the file and acceptable quality images.

Three factors that play a huge importance in the process of image optimization are:

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

By choosing the right combination of these three, you could reduce your images' size by up 80 percent.

Let's take a look at each one in more detail.

  1. Image File Format

For the majority of website owners, the three primary images formats that really count to consider are JPEG, PNG, and GIF. The right choice of format is essential to image optimization.

To make things easy You should choose JPEGs in the case of images or photographs that have a lot of colors. PNGs for simple images or when you require transparent images. You can also use GIF to create animated images.

For those who aren't aware of the distinction between each file type, the image format PNG is uncompressed , which means it is a higher quality image. The downside is that file sizes are much bigger.

However, JPEG is a compressed file format that reduces image quality in order to give a much smaller size file.

However, GIF only uses 256 colors together with lossless compression, which means it is the best option for animated images.

On WPBeginner, we use all three image formats , based on the kind of image.

2. Compression

The next thing is image compression that plays an essential role in image optimization.

There are many types and levels of compression available. Settings for every will differ based on the compression tool you employ.

The majority of image editors, including Adobe Photoshop, On1 Photo, GIMP, Affinity Photo and many others have built-in features to compress images.

You could also save your images in the normal way or use a web tool like TinyPNG or JPEG Mini for easier image compression.

While it's not the most user-friendly These two methods permit you to compress your images prior to uploading images to WordPress which is what we do with WPBeginner.

There are many well-known WordPress plugins, such as Optimole, EWWW Image Optimizer and many more that automatically compress images when you first upload them. Many beginners and even large corporations prefer to use these image optimization plugins because they are simple and quick.

We'll discuss more details about these WordPress plugins later in the article.

3. Image Dimensions

Normally, when you download a photograph from your smartphone or digital camera, it has a very high resolution and huge file dimensions (height and length).

Typically, these photos come with resolutions of 300 DPI and sizes ranging from 2000 pixels and higher. These photos of high quality are suitable for printing or desktop publishing. They are not appropriate for websites.

Reducing file dimensions to something less limiting can drastically reduce the size of an image. Resize images with an image editing program installed on your personal computer.

For example, we optimized the image with 1.8 Megabytes as its original file size, 300 DPI resolution, and dimensions of 4900x3200 pixels.

We opted for the Jpeg format to allow greater compression. We also changed the dimensions to 1200x795 inches, and it decreased the image file size to 103 KB. That's 94% less than the original file size.

Now that you know the three main factors involved in image optimization, let's take a take a look at various image optimization tools available to website owners.
