How to Save and Optimize Images for Web Performance?

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

Three things which play a major part 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 choose the best combination of these three, you can shrink your image size by up to 80%.

Let's examine each one in more specifics.

  1. Image File Format

For most webmasters, the only three image formats that truly require attention is JPEG, PNG, and GIF. The right choice of format is crucial in image optimization.

To simplify things You should choose JPEGs for photos and images with lots of colors. PNGs for basic images or when you require transparent images. You can also use GIF for animated images only.

For those that don't know the difference between each file kind, the PNG format is uncompressed , which means it is a higher quality image. The disadvantage is that it's file sizes are much larger.

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

However, GIF is limited to 256 colors and lossless compression. That is why it is the ideal option to use animated pictures.

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 on image optimization.

There are various types and levels of image compression that are available. the settings of each will differ based on the compression tool that you use.

The majority of image editing software like Adobe Photoshop, On1 Photo, GIMP, Affinity Photo and others are equipped with built-in compression tools for images.

You are also able to save images using a web tool like TinyPNG or JPEG Mini for easier image compression.

Although it's manual These two methods permit you to compress images prior uploading images to WordPress this is what we do with WPBeginner.

There are also several popular WordPress plugins like Optimole, EWWW Image Optimizer and many more that automatically compress images after you first upload them. A lot of newbies and large companies prefer using these images optimization plugins due to their ease of use and easy.

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

3. Image Dimensions

Normally when you import a photo from your phone , or digital camera, the image has a very high resolution and large file dimensions (height and width).

Most often, these images have typically a resolution of around 300 DPI with dimensions starting from 2000 pixels or more. These photos of high quality are suitable to print or desktop publishing. These images are not appropriate for use on websites.

Making the file's dimensions more reasonable can significantly decrease the size of the image file. You can simply resize images by using the image editing software installed on your computer.

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

We chose jpeg format for larger compression. The dimensions were changed of 1200x795 pixels. it reduced the file size to 103 KB. That's 94% less than the size of the original file.

Once you've mastered the three essential elements of image optimization now let's have a look at the various images optimization techniques for website owners.
