How to Save and Optimize Images for Web Performance?

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

Three factors that play an important importance in picture optimization are:

  • Image file format (JPEG vs PNG vs GIF vs tiff )
  • Compression (Higher compression = smaller file size)
  • Image Dimensions (height and width)

By selecting the most suitable combination of these three, you can shrink your image's size by as much as 80 percent.

Let's look at each one in more details.

  1. Image File Format

For the majority of website owners, the only three images formats that really have any significance comprise JPEG, PNG, and GIF. The selection of the proper file type can be crucial to image optimization.

To keep things simple For simplicity, it is recommended to use JPEGs for photos and images that have a lot of colors. PNGs for straightforward images or for transparent images, and GIF for images that are animated only.

For those who aren't aware of what is the difference between each type, the format of PNG images is uncompressed which means it's an image of higher quality. image. The downside is that PNG file sizes are significantly larger.

However, JPEG is a compressed file format which slightly reduces image quality in order to deliver a substantially smaller file size.

However, GIF only supports 256 colors along with lossless compression which makes it the most appropriate choice when it comes to animated photos.

On WPBeginner, we use three different image formats based on the type of image.

2. Compression

The other thing is image compression that plays an essential part within image optimization.

There are many types and levels of compression available. The settings for each will differ based upon the image compressing tool you select.

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

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

While it's not the most user-friendly These two methods permit you to compress your images prior to uploading them to WordPress as well, which is what we do with WPBeginner.

There are many well-known WordPress plugins like Optimole, EWWW Image Optimizer and many more that automatically compress images when you first upload them. Many newbies, and even larger corporations are using these image optimization plugins because they are simple and efficient.

We'll provide more information about these WordPress plugins in the following article.

3. Image Dimensions

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

Most often, these images have the resolution of 300 DPI and sizes that range from 2000 pixels or more. These high-quality photos are well-suited for desktop or print printing. These images are not appropriate for use on websites.

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

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

The format we chose was jpeg for greater compression. We also changed the dimensions to 1200x795 inches, and it reduced the file size to 103 KB. That's 94% less than the original size.

Now that you know the three primary factors that affect image optimization We'll take a look at different images optimization techniques for website owners.

Best ImageOptimization Tools and Programs

As we have mentioned previously, most image editing software come featuring image optimization in addition to compression adjustments.

For developers, they have an API that converts images automatically. For novices, they offer the WordPress plugin that will accomplish the task (more on this in the future).

JPEG Mini

JPEGmini uses a lossless compression technique that significantly reduces the size of images but without affecting their perceptual quality. You can also compare the quality of the original image and the compressed image.

Calculators  perform calculations using the fundamental mathematical functions like subtraction, addition, division, and multiplication. Many can also do more complicated calculations, like usual trigonometric functions as well as inverse trigonometric ( see trigonometry). There are few inventions that have had as significant an influence on our lives as the handheld or pocket, electronic calculator . These calculators can be used to help save time and decrease the likelihood of making mistakes and are found wherever you need to be able to use numbers frequently, in offices, retail stores, banks and laboratories, in schools, as well as in private homes.

Additionally, modern calculators are more portable than most computers although some personal digital assistants (PDAs) are comparable in size to hand-held calculators. Since calculators are reduced to a minimum, the day will come when devices that are the size of credit cards might be able to perform the exact calculations that are currently used in large scientific calculators.
