Image Optimization – Image Processing to Optimize Website

Image Optimization

Image optimization is the process of compressing images and setting display options for optimal use on the Internet. When putting images on the Internet, file size is an important factor to consider; you want a file size that is small enough to allow a reasonable download time but large enough to maintain satisfactory colors and detail. Therefore, three main graphic file formats are used on the Web: GIF, JPEG, and PNG.
When putting images on the web, you have to think about file size. This size should be small enough for the file to download quickly but still retain the desired colors and details.

Three Main Graphic File Formats are used on the Web: GIF, JPEG, and PNG. You can use the following Methods to Optimize Images in these Formats:

If you want to precisely optimize an image for use in web authoring applications such as Adobe Dreamweaver, you can use the Save For Web command. In the Save for Web dialog box, you can preview the image in different formats and with various optimization settings. You can also define transparency and animation settings.

To perform basic optimization, you can use the Save As command. Depending on the file format, you can specify Image quality, background transparencies or halos, color display, and download method.
Images are one of the elements that most weigh down the loading of a web page. Hence, we must be careful in processing them before uploading them.

Immediacy is one of the advantages of the Internet. We can get everything instantly just by asking. A piece of news, a piece of information, a video, a web page.

Today’s websites must deal with several factors. First of all, they are increasingly complex but at the same time, they must be opened in seconds regardless of the device and the quality of the user’s connection.

How to Optimize Images for the Net and Better Performance?

Image Optimization – The main goal of formatting your images is to find a balance between smaller file sizes and acceptable quality. There is more than one way to execute almost all of these optimizations. One of the most popular ways is to simply zip them before uploading them to WordPress. Typically this can be done using a tool like Adobe Photoshop or Affinity Photo. Some of these tasks can also be done using plugins, which we will talk about below.

The two main things to consider are the file set-up and the type of compression they use. Choosing the right combination of file format and compression type can reduce image size by as much as 5 times. You’ll have to research each image or file format to see which works best.
