How to Save and Optimize Images for Web Performance?

The key to success in optimization of images for optimization that is optimized for performance on websites is to find the best balance between the smallest file size and acceptable quality images.

The three things which play a major role in images 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 the three, you can reduce the image's size by as much as 80 percent.

Let's examine each of them in greater detail.

  1. Image File Format

Most website owners will agree that the only three images formats that really require attention include JPEG, PNG, and GIF. Picking the right type of file plays an important role in image optimization.

To keep things simple In order to keep things simple, use JPEGs when you want to use images or photos that have a lot of colors. PNGs for straightforward images or when you require transparent images. You can also use GIF for animated images only.

For those who don't know what is the difference between each type, PNG image format is uncompressed which means it's a better quality image. The drawback is that the file sizes are considerably larger.

On the other hand, JPEG is a compressed format, which reduces the quality of images to give a much smaller size file.

While GIF is limited to 256 colors along with lossless compression which means it is the best choice of animated graphics.

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

2. Compression

The following thing to consider is image compression that plays an essential role for image optimization.

There are different kinds and levels of image compression that are available. These settings will differ based upon the image compression tool you choose to use.

The majority of image editing software like Adobe Photoshop, On1 Photo, GIMP, Affinity Photo and others include built-in features for image compression.

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

Although it's manual but these two techniques allow the compression of images prior to uploading images to WordPress, and this is what we do with WPBeginner.

There are also a variety of popular WordPress plugins like Optimole, EWWW Image Optimizer, and others that can automatically compress images after you first upload them. Many novices and even huge corporations use these image optimization plugins due to their ease of use and simple.

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 an extremely high resolution as well as the dimensions of the file are large (height and wide).

Most often, these images have typically a resolution of around 300 DPI and sizes starting at 2000 pixels and up. These high-quality photos are well-suited to print or desktop publishing. They are not suitable for use on websites.

Sizing down the dimensions of files to something more reasonable can significantly decrease the size of your images. It is easy to resize images by using an image editor software on your personal computer.

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

We decided to go with the Jpeg format because of more compression. We changed the dimensions of 1200x795 pixels. it reduced the image's size to 103 KB. This is 94% smaller than the original size.

Now that you've learned the three essential elements of image optimization, let's take a take a look at various images optimization software for webmasters.
