How to Save and Optimize Images for Web Performance?

The most important factor in successful image optimization on the web is to find the perfect balance between the most compact file size and acceptable quality of the image.

Three things that play a huge influence on images 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 can reduce your image's dimensions by up to 80%.

Let's examine each of them in greater specifics.

  1. Image File Format

For the majority of webmasters, the only three image formats that truly should be considered include JPEG, PNG, and GIF. Picking the right type of file is crucial for image optimization.

To simplify things, you want to use JPEGs when you want to use images or photos with lots of colors. PNGs for basic images or when you require transparent images, and GIF to only use animated images.

For those who don't know the differences between each file type, the image format PNG is not compressed, which means that it's an image of higher quality. image. The downside is that file sizes are much larger.

However, JPEG is a compressed file format , which can slightly diminish the image quality to make it much smaller file size.

In contrast, GIF only supports 256 colors along with lossless compression which makes it the best option for animated images.

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

2. Compression

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

There are a variety of types and levels of image compression that are available. The settings for each depend on the image compression tool you choose to use.

A majority of image editing tools, such as Adobe Photoshop, On1 Photo, GIMP, Affinity Photo and others include built-in features to compress images.

You are also able to save images and then use a web application like TinyPNG and JPEG Mini for easier image compression.

Though it's a little manual These two methods permit users to compress images before uploading them to WordPress, and this is what we do on WPBeginner.

There are also many popular WordPress plugins like Optimole, EWWW Image Optimizer and others that automatically compress images once you upload them. A lot of novices and even big companies choose to utilize these image optimization plugins since it's simple and simple.

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

3. Image Dimensions

Normally, when you transfer a photo from your phone or a digital camera, it comes with an extremely high resolution and enormous file dimensions (height as well as width).

In general, these photos have an average resolution of 300 DPI and sizes ranging from 2000 pixels and more. High-quality images are ideal for desktop or print printing. They are not suitable for use on websites.

A reduction in file dimensions to something less limiting can drastically reduce the size of the file. You can easily resize images with the software for editing images on your personal computer.

As an example, we have optimized an image to have 1.8 MB original file size With a 300 DPI resolution, and dimensions of 4900x3200 pixels.

We opted for the Jpeg format to allow more compression. We changed the dimensions to 1200x795 pixels. In addition, it reduced the image file size to 103KB. That's 94% less than the size of the original file.

Once you've mastered the three essential elements of image optimization, let's take a look at different images optimization tools for owners of websites.
