How to Save and Optimize Images for Web Performance?

The most important factor in success in image optimization in order to optimize web-based performance, is to strike the perfect balance between lowest file size and acceptable image quality.

The three factors which play an integral role 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 most appropriate combination of the three you could reduce your image size by up to 80 percent.

Let's take a look at each of these in more details.

  1. Image File Format

Most website owners will agree that the three primary images file formats that actually have any significance can be described as JPEG, PNG, and GIF. The selection of the proper file type is crucial for image optimization.

To make things easy It is best to use JPEGs for photos or images that have a lot of colors. PNGs to create simple images, or for transparent images. You can also use GIF for animated images only.

For those who aren't sure of what is the difference between each kind, the PNG format is uncompressed which means it's a more high-quality image. The disadvantage is that it's file sizes are significantly larger.

On the other hand, JPEG is a compressed file format which slightly reduces image quality in order to provide a significantly smaller size file.

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

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

2. Compression

Another thing to consider is compression that plays an essential part on image optimization.

There are several types and levels of compression that are available. the settings of each differ based upon the image compression tool that you use.

Many image editing tools such as Adobe Photoshop, On1 Photo, GIMP, Affinity Photo and many others have built-in features to compress images.

You can also save pictures in normal format and then make use of a website tool like TinyPNG , or JPEG Mini for easier image compression.

Although it's a bit manual These two methods permit the compression of images prior to uploading them to WordPress, and this is the process we employ on WPBeginner.

There are also a variety of popular WordPress plugins, such as Optimole, EWWW Image Optimizer and many more that automatically compress images when you upload them for the first time. Many beginners and even large corporations choose to use these image optimization plugins since it's simple to use and is convenient.

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

3. Image Dimensions

Normally, when you download a photograph from your phone , or digital camera an extremely high resolution as well as big file dimensions (height and width).

Most often, these images have resolutions of 300 DPI and dimensions starting from 2000 pixels or more. These photos of high quality are suitable for printing or desktop publishing. They are not appropriate for websites.

Reducing file dimensions to something more manageable can significantly reduce the size of the image file. Simply resize images using an image editor software on your personal computer.

In this case, we optimized an image to have 1.8 MB original file size and 300 DPI resolution, and image dimensions of 4900x3200 pixels.

We decided to use the jpeg format for larger compression. The dimensions were changed to 1200x795 pixels, and it reduced the image's size to 103KB. That's 94% less than the original size.

If you're aware of the three most important aspects of image optimization Let's take a review the different image optimization software for webmasters.
