How to Save and Optimize Images for Web Performance?

The key to success in picture optimization in order to optimize web-based performance, is finding the ideal equilibrium between the lowest file size and acceptable image quality.

The three factors which play an integral influence on the process of image 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 all three, you can reduce the image size by up to 80 percent.

Let's examine each of them in greater specifics.

1. Image File Format

For most website owners, the three primary image file formats that need to be considered to consider are JPEG, PNG, and GIF. The choice of the correct file format is crucial to image optimization.

To make things easy To keep things simple, you should use JPEGs for photos and images with lots of colors, PNGs for images that are simple or when you need transparent images, and GIF for images with animation only.

If you don't know the difference between each file kind, the PNG format is not compressed, which means that it's an image of higher quality. image. The downside is that file dimensions are larger.

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

And GIF only uses 256 colors along with lossless compression which means it is the best option of animated graphics.

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

2. Compression

The following thing to consider is image compression, which plays an important part in image optimization.

There are various types and levels of compression that are available. What settings are used for each will depend on the image compression tool you choose to use.

Most image editing tools like Adobe Photoshop, On1 Photo, GIMP, Affinity Photo and more come with built-in compression tools for images.

You may also save images by default using a web application like TinyPNG and JPEG Mini for easier image compression.

While it's not the most user-friendly These two methods permit you to compress images prior to uploading the images to WordPress that's the process we employ on WPBeginner.

There are many other popular WordPress plugins like Optimole, EWWW Image Optimizer and many more that automatically compress images after you upload them. Many beginners and even large companies choose to utilize these image optimization plugins due to their ease of use and quick.

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

3. Image Dimensions

Normally, the moment you import a picture from your phone or digital camera, it comes with an extremely high resolution and huge file dimensions (height as well as width).

The majority of these photos have typically a resolution of around 300 DPI with dimensions starting from 2000 pixels and even more. High-quality images are ideal for printing or desktop publishing. These images are not appropriate for websites.

The reduction of file sizes to something sensible can drastically decrease image file size. You can easily resize images using an image editor software on your computer.

In this case, we optimized our photo to 1.8 1 MB of file size and 300 DPI resolution, and image dimensions of 4900x3200 pixels.

We chose jpeg format for more compression. We changed the dimensions to 1200x795 pixel, and it reduced the file size to 103 KB. That's 94% less than the original file size.

Once you've mastered the three main factors involved in image optimization we can take a look at different images optimization tools available to website owners.
