How to Save and Optimize Images for Web Performance?

The key to successful image optimization to improve web speed is finding the ideal balance between the smallest file size and acceptable image quality.

The three factors that play a crucial impact on optimization of images are: 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 select the most appropriate combination of all three, you can decrease your image's size by as much as 80 percent.

Let's look at each of them in more specifics.

  1. Image File Format

The majority of website owners believe that the only three image formats that really count to consider are JPEG, PNG, and GIF. The selection of the proper file type is crucial in image optimization.

To make things easy It is best to use JPEGs for photos and images with a variety of colors, PNGs for basic images or when you need transparent images, and GIF for animated images only.

For those who aren't sure of what the distinction is between each kind, the PNG format is uncompressed , which means it's a superior quality image. The drawback is that the file sizes are much bigger.

However, JPEG is a compressed format that can reduce image quality in order to provide a significantly smaller size file.

And GIF can only use 256 colors along with lossless compression which makes it the best option in animated image.

On WPBeginner we employ all three image formats , based on the type of image.

2. Compression

The next thing is image compression, which plays a major part when it comes to image optimization.

There are different kinds and levels of image compression that are available. What settings are used for each will differ depending on the compression tool you use.

The majority of image-editing tools like Adobe Photoshop, On1 Photo, GIMP, Affinity Photo and many others have built-in image compression capabilities.

You can also save images normally but then you can use a Web application like TinyPNG and JPEG Mini for easier image compression.

Though it's a little manual These two methods permit you to compress images prior to uploading the images to WordPress, and this is the process we employ on WPBeginner.

There are many other popular WordPress plugins such as Optimole, EWWW Image Optimizer and others that automatically compress images once you upload them. Many newbies, and even larger corporations prefer to use these images optimization plugins because it's easy and simple.

We will share more about these WordPress plugins in the next article.

3. Image Dimensions

Normally, when you download a photograph from your smartphone or digital camera, the image has an extremely high resolution as well as the dimensions of the file are large (height and wide).

The majority of these photos have the resolution of 300 DPI and sizes that range from 2000 pixels and up. These high-quality photos are well-suited to print or desktop publishing. They're not suitable for websites.

Making the file's dimensions less limiting can drastically reduce the size of images. You can easily alter the size of images using an image editor software on your personal computer.

We optimized, for instance, the image with 1.8 Megabytes as its original file size with a 300 DPI resolution, and dimensions of 4900x3200 pixels.

We opted for the Jpeg format to allow larger compression. The dimensions were changed to 1200x795 inches, and it reduced the image's size to 103KB. This is 94% smaller than the size of the original file.

Now that you know the three primary factors that affect image optimization we can take a review the different image optimization tools for owners of websites.
